“should i have air duct cleaning -air duct cleaning methods”

Steve is the person telling the truth here about AC duct cleaning and AC filter cleaning and changing. Many of the other comments come from uninformed homeowners and those who want to get people to hire AC contractors and pay hundreds of dollars for useless services.
Go ahead and look inside your system where you change your air filter. A buildup of dust and debris means it is time to clean the system. According to the HVAC Inspection, Maintenance, and Restoration Association (NADCA), a six-room house can collect as much as 40 pounds of dust, pet dander, and chemicals in its air ducts each year! This dirty air is recycled over and over again throughout your home, five to seven times a day. How does this affect your home? Here’s a list of common problems in homes with dirty air vents that haven’t been cleaned in five or more years:
Sears Air Duct Cleaning follows the duct-cleaning guidelines established by the National Air Duct Cleaners Association (NADCA) guidelines. The technician covers the floor and install corner gardens to prevent damage to your home, attaches a powerful vacuum to the main duct, and then uses specialized tools to knock the dust loose so the vacuum can collect it. Before leaving, the air-duct cleaning technician answers any questions you might have and makes sure you’re satisfied with the work.
He proceeded to clean each heat register by removing the grille and blasting it with an air pressure hose toward the duct opening thinking that the dust would magically be sucked inside. In one room this caused a ceiling smoke detector to go off because the excess dust fooled it into thinking there was smoke. I put my hand in front of a register he wasn’t working on and could hardly feel a suction. Although we discussed how I open and close damper doors, I realized later that he never checked, opened or adjusted them during the cleaning. He could have closed all but the one he was working on in order to increase suction results. His next step was to blast air into the duct and then attach a “squid-like” device that slapped around inside the duct as far as he could reach. This is important! In a newer house, ducts have long straight runs from the furnace. In older houses like mine they can turn and twist. In fact, the duct have a problem with runs straight up from the basement inside a wall and turns 90 degrees into a soffit for three feet then into two 90 degree turns to get into the floor joist area for another two feet and finally a 90 degree turn up to the second floor register. When he cleaned this one he could only get three feet into the register with the hose or squid because of the turns. That was the case with most. Hardly what could be described as a decent cleaning.
as you say it is not required to be done as niether are you required to put wax on a new car paint job as is already sealed. yet almost everyone when washing their cars chooses to add more wax or just wax the car.
You’d be surprised how many HVAC companies don’t even have websites. How accountable can we think they are, when a phone number can be changed at the drop of a hat? I’m not hiring one without a website. Never again.
If the one noticeable spot is where the wall [or ceiling or floor] is white…….first…..take a pair of needle nose pliers and bend each louver of the register to a straight outward position [as they all come brand new with a slant to each side]….so the register is shooting all supply air straight outward. If its a round register [in ceiling]…..no help there. You also should always burn soy or beeswax candles.
I’ve read a lot of replies on here and I’m sorry for people’s bad experiences with companies who shouldn’t be cleaning ducts. The only problem I have with the post on Angie’s list is the pricing is a bit low for companies like mine to make a profit. I have owned a NADCA (National Air Duct Cleaners Association) Certified duct cleaning company since 1999. We do residential, hospitals, factories, and commercial buildings. We send a NADCA certified ASCS (Air Systems Cleaning Specialist) and VSMR (Ventilation System Mold Remediators) specialist to every job we do, including residential jobs. It cost us a lot to keep our certifications up, we have to go to classes each year for this. Our prices are higher than the prices Angie’s List stated, but its like the saying goes, you get what you pay for. A home that is 1500 sq ft would take 2 technicians about 4 hours to do the work because most the homes in the area I cover have crawl spaces, and they have to crawl under the house to clean the ductwork. This is 8 total work hours for this job, plus the cost of travel time and gas to get to the jobsite. The cost of the job would be $750. A larger home would be more depending on the size of the house. That is a bit higher than Angie’s list stated, but this covers everything with no hidden cost. And to send 2 qualified people to a job site its going to cost more than 1 guy going in with a shop vac type system and telling the home owner that he doesn’t need to go under the house or in the attic to clean the duct work. We get a lot of jobs going behind these type duct cleaners to fix what they messed up then the home owner is stuck paying 2 companies. One last thing, make sure the person is NADCA certified, and not just say certified. Some of the companies who make shop vac type systems will teach a day and a half class and then give the person a certification saying they can operate that duct machine. This is NOT the same as NADCA certification. NADCA is the only certification recognized by the EPA for cleaning HVAC Duct. Good luck and have a great day.

“youtube air duct cleaning +air duct cleaning business”

Air Duct Cleaning is one of the healthiest HVAC maintenance decisions you can make. Overtime, the walls of your furnace and air conditioning system become laden with particles of dust, allergens, and other debris. Some of these contaminants may cause allergic reactions others significantly decrease the efficiency of your heating or cooling system.
At Air Quality Systems, we use the “total source removal” method of cleaning—the only method recognized by the National Air Duct Cleaners Association. Our state-of-the-art equipment has been specifically designed for ductwork cleaning. You can feel confident that you’ll breathe nothing but clear air after we’ve cleaned your ducts.
The cooling coils the air comes into contact with appear to need UV-C lights on them in humid climates. That’s the biggest thing. If the ducts have never been cleaned, then getting that done goes without saying. But those coils need to be cleaned, disinfected, and then UV-C light(s) installed to prevent mold & bacteria build-up in the future on them. That appears to be chiefly responsible for the dirty laundry and/or sour milk smell coming from forced-air AC systems in humid regions.
Ok what you said is true but in most cases ducts are in a duct flex format, and knowing that the dust in people’s flex duct is just surface dust, any real debris that are in the duct itself will result in very little to no air flow which will keep your unit from performing properly, but if it is true allergy reasons then replacing your duct system is better for overall better air quality, plus if you do pay attention to the warranty on flexible duct is that it only has a 10 year warranty and typically only lasts for 20 years so do your research before having a duct cleaning, and to add one more thing if your duct work is completely metal and you can’t see visible insulation then your duct on the inside has insulation inside of it, if you replace that with duct work that is clean metal on the inside and wrapped with insulation on the outside then it will further reduce the air bourne fiberglass and dust.
We moved to a house built in 1965 from a 1915 house with a dirt basement. Against what I anticipated, the 1965 house was much dustier. It was like felt on top of everything. I cleaned and cleaned and it did become less dusty over time. We then found out a cat lady with over 2 dozen cats lived in the house in the past. We then had to get our furnace replaced and I was able to look down some of the duct work, the dirt and debris was 3-5 inches deep. Additionally, the basement ducts were entirely plugged with debris including dirt, seeds, ants, toys, etc. I had already removed what I could from those. We had our ducts cleaned last year, and the dust in the house is greatly reduced. Also have lost the runny nose I got after moving here. There are duct cleaning con artists out there, but ours did a good job.
As early as February of 1990, Duct & Vent Cleaning of America, Inc. joined NADCA, the HVAC Inspection, Cleaning and Restoration Association. In fact, we were the first company to be allowed membership that used portable hepa vacuums in the cleaning process. Today there are many methods to clean ductwork and each job needs to be handled differently in the approach to achieving the desired results.
Before you choose any duct cleaning service provider, interview as many service providers as you can. Ensure that the service provider is certified by the National Air Duct Cleaners Association or NADCA. Make sure that they hold a good standing in the Better Business Bureau and have all the necessary certifications and license. Be clear about their terms of service. Make sure they have the right equipment to do the job. It is best to go for a company that has been tried and tested successfully by any of your acquaintances or opt for a service provider that has been in the business for quite some time.
I hope that those customers you have with breathing problems don’t follow your advice too closely. You are doing them a disservice. Dirt in your ducts does not always stay there, depending on what the contaminants are. I bet you tell your customers not to worry about mold either- just to kill it with bleach. Educate yourself before opening your mouth- You may kill someone someday with your opinion.
Cleaning your ducts will also keep your home cleaner! As dust and debris, makes its way through your system, it ends up blowing at you through your supply air vents. A clean home is a happy home, and less time dusting leaves more time for leisure.
Portables powered by fans are rated by “clean-air delivery rate” (CADR), which measures both air movement and gunk-trapping effectiveness. It’s important to buy a filter that’s big enough. Manufacturers recommend that the CADR be at least two-thirds the room’s area in square feet — so a 15-by-20-foot room (300 square feet) would need a filter with a CADR rating of 200. (The calculation assumes 8-foot ceilings.)

Every time you replace your air conditioner, I would also consider replacing your ductwork as well.  Ductwork has insulation and other components that deteriorate over time and should be replaced regularly just like your HVAC system.  Furthermore, the joint seals between duct segments will also deteriorate over time so keep this in mind.
I’m having my duct work cleaned this Saturday. Have a coupon for $49 through Amazon. Job normally $249. Had my basement remodeled about 18 months ago. The contractors were very thorough at blocking the vents, as far as I can tell. The offer is for HVAC and dryer vent cleaning. My house is 11 years old. I figured, $49 is not much. I appreciate your tips on not getting talked into any additional service, not to use solvents to clean, the certification information and before and after pictures. Very useful and I’ll be sure that all I spend is the $49 for the voucher.
Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space. It is important to keep in mind that dirty air ducts are only one of many possible sources of particles that are present in homes. Pollutants that enter the home both from outdoors and indoor activities such as cooking, cleaning, smoking, or just moving around can cause greater exposure to contaminants than dirty air ducts. Moreover, there is no evidence that a light amount of household dust or other particulate matter in air ducts poses any risk to your health.

He noticed a big push to replace systems instead of maintain them. This is how Bee’s Air Duct Cleaning was born. Bee and the rest of us at Bee’s air duct cleaning believe in taking care of the furnace and air conditioner you have, so it runs as efficiently as possible and last a long long time.
Even though there is no evidence to support the claim that duct cleaning benefits your health, there is also no evidence that it harms your health if done properly.  So if you have just had your ducts cleaned, don’t fret about it.  It wasn’t a bad investment in your health and overall it definitely helped more than it hurt.

The time for the service given to me was between 12 and 6PM. The technician’s arrived at 10AM, and also I didn’t receive any prior notification that they are arriving early. That was a major inconvenience, although the technicians were very understanding and courteous. Somebody in the administration surely goofed up. Not expected from SEARS!
9. Replace furnace filter. Buying a better filter will definitely cut down on the dust in your home. But the better the filter, the more often you should change it; a dirty filter restricts the airflow to the fan, which results in the blower motor running hotter and reducing its lifespan. How often you should change your filter depends on your home, your pets, and your location.
SERVPRO Franchise Professionals routinely inspect the heating, ventilation and air conditioning unit (HVAC).  Keeping them clean can extend the life of the equipment. This can in turn save you money and give you cleaner air to breathe.
I am NADCA Certified Air Systems Cleaning Specialist. Over the years I have learned on simple answer to this questions: there air duct cleaners and there are pretenders. There will be no benefit at all if you use on the very cheap pretender because they will not really clean anything. On the other hand if you call a qualified air duct cleaner with a NADCA Certification you will, like 99% of my customers, report improvement with your respiratory problems, you will see less dust and the job will pay for itself with energy savings and repair prevention.
The fogger is placed in the air conditioner’s intake with the system’s fan running to sanitize the entire system and to inhibit the future microbiological growth by utilizing a natural disinfectant that is harmless to occupants.
I had my a/c and furnace serviced and cleaned as well as my ducts cleaned and everything went smoothly and for a reasonable price. Evelyn was excellent at keeping me updated on the progress of the work since I wasn’t able to be there in person. Great customer service and speed of scheduling.
Tom Bergendahl of Wakefield, Massachusetts, wishes he’d hired a reputable service to clean his air ducts instead of a local company that has since gone out of business. “Duct cleaning is a fragile operation, and if you don’t do it right, you can damage the system,” he says. “They completely wrecked the motor.”

We are a hvac company that provide air duct cleaning service are minimum charge $400 to do a proper air duct cleaning with 2 techs avg 3-6 hours that includes sanitizing. I get phone calls all day about the $99 your not going to get much of a cleaning for that price it for them to get there foot in the door and up sell that the only way for them to stay in business. Just from my 15 years of duct cleaning customers who contact our air duct cleaning specialists often start the conversation with this question and it can be a hard one to answer. Conditions in every building vary and depending on several factors, it may be time to have your residential, commercial, or industrial space inspected and cleaned. Some of these factors can include:
After the air duct cleaning service was complete, one of the men gave me a video inspection through one of the vents, and it was amazingly clean. The duct cleaning service took approximately 2 hours and they left no mess. Since the service, I have noticed very little dust inside my house.

A proper home air duct cleaning costs anywhere from $400-$1,000, depending on the size of the system to be cleaned, the type of services offered, the regional climate and the level of use the ventilation system gets, the type of materials inside the ductwork and the amount of contaminants (dust, mold, etc.). A 1,400-square-foot home with only one system of ducts will usually be at the lower end of the scale, while a 3,500-square-foot home with multiple heating/cooling systems is at the upper end of the price range.
I’ve been scammed too. I paid the living social special and they came out and did a sucky job and said we had mold so I paid $330 for it and my neighbor said I shouldn’t have because it is hard to get mold out here were we live. They used a shop vac and a bottle spray which probably had clorox. $330 down the drain for free.
You should be aware that although a substance may look like mold, a positive determination of whether it is mold or not can be made only by an expert and may require laboratory analysis for final confirmation. For about $50, some microbiology laboratories can tell you whether a sample sent to them on a clear strip of sticky household tape is mold or simply a substance that resembles it.

I bought a Supply Vent Cleaning + Furnace Inspection service with GreenHeat service back through Amazon deal in Nov and used it before it expires. Cost 50$ for that deal. 2 guys came did the vent cleaning very quick and after inspecting the furnace, talked me into doing a deep cleaning for the blower. After 20% discount, price was 375, so I bargained down to 320$. They took the blower out, cleaned throughly (it was very dirty). Also sanitized and vacuum the rest of the furnace. I am satisfied with their service.
The dust, pollen, dander, sawdust, mold spores and other lightweight particles that float in your home’s air eventually circulate through your heating and cooling system. Your furnace filter traps some of this airborne debris—if you replace your filter when it’s dirty—but some settles in the ductwork. That accumulated dirt is available to move back into the airflow and blow into your rooms. Your furniture and floors get dusty sooner, but worse, your home’s air quality can deteriorate. If you have respiratory problems, you might find it more difficult to breath. If you suffer from seasonal allergies, you can be exposed to pollen all year long. Dirty ducts also make your heating and cooling system less efficient. The filter clogs faster, so the system has to work harder to move air—and you can end up with a higher energy bills. Also, particles of dirt wear on the components in your HVAC system, which can shorten its life.
As an authorized Trane® dealer, we offer high-efficiency heating and cooling systems that both save you money and ensure your comfort. This also means you are sure to find the best deals on industry leading energy efficient central air & furnace models! We also provide sales, service, and installation of furnaces and air conditioners from a wide array of other manufacturers including Carrier, Payne, Goodman, and many more! To help maintain your equipment’s efficiency, extend its life, and keep your heating/cooling bill to a minimum, call Chicagoland’s premier HVAC partner. We also offer annual service contracts.
Avoid Sealants and Sprays: Both the EPA and the NADCA recommend against the use of sprayed sealants or other potentially harmful chemicals inside air ducts. Biocides and anti-microbial treatments are also iffy, since the chemicals may cause more harm than good to your health. No chemicals are currently registered with the EPA for use inside ductwork.
If you do have children or spouses who suffer from allergies or reactions to the air turning on, it might be an indication there is something in there making them react. They should speak with their doctors and then get a heating and cooling contractor out if it is recommended that airborne pathogens are the cause of their reaction.

Excessive Dust: Excess dust and debris built up in the ductwork could cause your home to become dustier. Ask your contractor to use a camera to check inside the ductwork for this problem and show you the evidence before they begin to clean.
Gas-phase air filters remove gases and odors by using a material called a sorbent, such as activated carbon, which adsorbs the pollutants. These filters are typically intended to remove one or more gaseous pollutants from the airstream that passes through them. Because gas-phase filters are specific to one or a limited number of gaseous pollutants, they will not reduce concentrations of pollutants for which they were not designed. Some air cleaning devices with gas-phase filters may remove a portion of the gaseous pollutants and some of the related hazards, at least on a temporary basis. However, none are expected to remove all of the gaseous pollutants present in the air of a typical home.
Trane® prides themselves on their product reliability. Most manufacturers use the same parts available to everyone. However, Trane® uses their innovations to design, build & rebuild some of their own parts.
Development of mold and mildew. Air ducts that are exposed to moisture, such as most in the Dallas area, can grow dangerous mold and mildew; that build-up can subject you and your family to airborne toxins if it’s not treated properly.
I replaced all the ducts but the trunks in my 1969 home when I replaced the horizontal furnace under the house with a gas pack. I got advice from a friend who was an HVAC contractor. I was surprised to find the trunks and other ducts very clean. I replaced the individual runs with flex primarily for the insulation. I wrapped the trunks with insulation also.
The EPA recommends having the air ducts cleaned only as needed[3] — that is, when there is substantial visible mold growth inside, if the ducts are infested with rodents or insects, or if they’re clogged with excessive amounts of debris.
Verify Results: You should be offered a complete visual inspection of the HVAC system and ductwork, either in person or by remote camera. Make sure every single duct is clean, and insist on an inspection of the inside of the HVAC unit, before paying for the service.
1. Cover supply registers. Start by covering up your supply air registers (openings that supply heated air to the rooms) with paper towels. You do this to keep dislodged dust from drifting into the rooms as you work. Simply lift the register, wrap the paper towel over the top of it, and replace it.
Quality and price should come hand in hand, a too-good-to-be-true price for an efficient air duct cleaning will not give you the quality that you wanted. To make sure you are getting your money’s worth, check reviews of air duct cleaning companies, certifications from industry since this work requires continuous learning due to new techniques and research breakthrough from time to time. My mom is located in Arizona and they trust J&M Restoration air duct cleaning company, they have an A+ BBB rating, they used EPA approved sanitizing agents, their technicians are NADCA certified, and the company is certified by the Institute of Inspection, cleaning and Restoration. Make sure to shop around and get written estimates first.
http://davewirth.blogspot.com/2014/01… There are several video’s on youtube of companies that clean air heating vents, but there are none that show how you can clean them yourself. This is a video i made when i decided to try and clean my air ducts by myself. I used a shop vac and a leaf blower to do the entire job.
Having evaporator and condenser coils cleaned could cost between $100 and $400. If your coils can be accessed in-place, you’ll be looking at a lower service cost. If your technician needs to remove the them first, the cost should be around $400. Having the evaporator and condenser coils cleaned can have a significant impact on the efficiency of your system. If your coils are excessively dirty, they won’t be able to do their job and your system will have to work harder. Keeping up with the hygiene of these components can save you money in both the short and long-term. For example, replacing evaporator coils can cost anywhere from $650 to $1200.
After a scheduled inspection, the technician recommended a deep duct clean, including disassembly of the motor/blower and heat exchanger. The next day, two guys called me to let me know they were on their way (early!). They wore shoe-booties while in the house and used a pump the size of a large fridge. They told me exactly what they were doing and in what order. They removed the ceiling registers and cleaned them. Afterward, they even vacuumed the areas around the registers to get fallen paint/dust. I have a new baby coming and while I initially thought $700 was high, I found that for a 3000+sq ft house and two 5-ton units it was a great deal.
20 yrs ago I bought the house I am in and a Central H/A was installed at that time. At the beginning of ea season I have the unit serviced. Every yr since I have owned the house I have had to have freon added and been told that I must have a freon leak. Fast forward to this yr when I hired a new company to do the service. They went up into the attic as part of their overall servicing. Nobody else has ever done that. He came down showing me pics on his camera phone of ducts that were not even connected to anything and in my estimation have probably been laying there for 20 yrs. Of course he fixed this. I have not needed freon this year either. I have been complaining to friends about the huge amount of dust and how I can’t keep up with the cleaning away of it for a long time. Now it makes so much sense.To me it is like that duct work was just up there laying around and every time my unit was blowing, all the insulation, debris, dust and whatever else over the years was just randomly filling up those ducts. What now that they are re-connected? Will it be better? Or am I someone that needs to have my ducts cleaned? I am so confused after reading all these comments. Can one of you experts tell me what you would do before I spend a bunch of money that I don’t really have? Thank you for any input you can provide. Also, feel free to respond to email address [email protected]
As a person with severe mold allergies, I live in a the South where the climate naturally breeds molds.We noticed a difference when we had our ducts cleaned.The company used a vacumn type system and covered all of our vents with plastic that was held up by the suction. We had no damage, no leaking dust/dirt back into the house and it took several hours. I think if you use a reputable company it makes the world of difference. Now we use better air filters and also have a UV light to prevent mold growth on ours system.We ‘d do it again when the time comes. From your car’s air filter to your dryer…anything works more efficiently when it is not filthy dirty.That’s just common sense.
Pulling large volumes of air toward the truck, we now feed our soft rubber, high pressure air scrubbing tools down each of the vent lines forcing all of the contaminants into the trunk line where its extracted into the truck.  This removes dirt, dust, pollen, chemical residue and pet dander that has collected over the years.
Yes, ducts can look terribly dusty. However, that dust will not become aerosolized during the normal operation of your furnace. There is an easy way to test this. Rent a particle counter and test the air flowing out of your registers before and after cleaning. You will not see any improvement in the air quality or any reduction in the airborne dust level. Think of it this way. Duct cleaning companies tell you that you need to clean your ducts when you can see a layer of dust in your ducts. Yet that very layer of dust is proof that duct cleaning is unnecessary, because that dust proves that the air movement in your furnace is not fast enough to re-aerosolize the dust.

A house breathes just like you an I.For example every time your clothes dryer comes on it automatically creates a negative pressure inside the home.So if air goes out of the living area it has be replaced…..now look above the ceiling fan ….you see the cover…underneath that is a hole straight to your attic….Now the stuff on your ceiling fan you call dust…call it insulation,rat fecies or anything else that is in your attic that could be pulled in your due to a negative pressure.

I recently had my air ducts cleaned after never having done it since I’ve lived in my home for 20 years. Mine and my children’s level of discomfort due to dust and allergens seems to have decreased significantly since we used Aircare Services in southern MA.
You cannot control where drywall dust goes in a new home. It will stick to walls, cupboards, etc. It is definitely a good idea to have it done on a new home purchase as the builders don’t do it. Then you should be good to go. Be sure to clean all surfaces in the home first.
The fact is if they are dirty why not clean them. As for the Dr’s comment about if it is not disrupted it is fine. As a pet owner sometimes un disrupted pet hair will sit in the corner of a room or under a counter un disrupted but I still clean it when I notice it. Just because you cant see it doesn’t mean you should leave it there to collect more and more. The people that don’t want there air ducts clean either simply cant afford it but would like it done. OR! the crowd that are to cheap.. You should Clean all portions of your house.
These guys know what they are doing and do it right. The team Kent sent out did a very thorough job and were very polite and professional. We can already tell the difference. Kent came by to inspect the work and even threw in cleaning our short dryer vent. Let me say that the guys took down and scrubbed every vent, some with mold (not black mold). Kent gave us some great tips to extend the time between cleanings and was not pushing for unnecessary services or too frequent follow on cleaning. I will gladly call them in 5 years to re-clean our ducting, vents, fan, motor, and coil.
This was only for cleaning the dryer vent, but I would hire them next time I need ducts and other items. Very professional, polite, and timely. They were even early for the appointment. Very satisfied with the job done.
Air Duct Cleaning companies supposed to come up with the packages and clear explanation what and how they going to do the job. Method described below by Steve Marshall called “Push and Pull” and it is one of the most effective ways to remove dust and debris from the “length of your house”. 
If you have someone who smokes indoors, cleaning your ductwork is not the answer.  Your ductwork itself is non-porous and will not retain odors.  It is actually the dust in your ductwork that is retaining the odor, so using a quality air filter will again solve this problem before it begins.
Duct & Vent Cleaning of America, Inc. was founded in April of 1989 by Ron Eckman, and was soon joined full time by his cousin Michael Vinick in West Springfield, MA. The company began as a result of Ron recognizing the importance of duct cleaning and that it was an important emerging market. Very soon, Ron turned over control of the company to Michael who has been running the company ever since.
What if you just moved into a new house but the air conditioner is not due for a replacement?  This is the only circumstance in which I would consider having your ducts cleaned.  I would also recommend that the cleaner you choose be an HVAC contractor as well so they can check your ductwork for leaks.
Both Dalton and James were professional and extraordinarily respectful. Dalton took the time to explain a few tips around caring for my HVAC system, which was very much appreciated. I need a little time to determine whether the cleaning meets my expectations, as I “live” with it, I will understand those results. I can’t speak highly enough of Dalton and James. Thank you.
At Mr. Duct, we understand that the decision to service the HVAC system may be a new and confusing process for many home and business owners. It may even seem that every air duct cleaning company has their own special money-making gimmick, further complicating the research and comparison process for you.

“reliable air duct cleaning -air duct cleaning benefits”

In reading through all this about duct cleaning, THE ONE preventative measure people need to realize is that a poorly installed HVAC system that is not sealed and air tight to ensure that ALL indoor air passes through a GOOD air filtration system IS THE best means of ensuring your ducts remain clean. Duct cleaning does not now and will NEVER improve an HVAC systems efficiency. Proper maintenance and installation are the key just as improper installation practices allow for dust infiltration into the duct system. I am a state licensed contractor in Texas, and unless people have their hvac system sealed and/or properly installed, duct cleaning is an absolute waste of money. My duct system is 12 years old as is as clean today as the day I installed the system with ductwork. SO before ANYONE jumps on the bandwagon of duct cleaning, get with your hvac professional FIRST.

“Honesty is everything with these people. They checked all the vents connected to my dryers and said I didn’t need any cleaning of the ducts since they were all clean. Two other companies gave me price per vent without looking at the job. The gutter maintence earned my future business through honesty”
In the last several years, a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities. Other research indicates that people spend approximately 90 percent of their time indoors. Thus, for many people, the risks to health may be greater due to exposure to air pollution indoors than outdoors. – Environmental Protection Agency.

Ultimately, the decision to clean air ducts comes down to a homeowner’s own judgment. “Look at your filter and see if it’s dirty,” Vinick says. “Take a look inside the return grills and supply ductwork and you’ll be able to tell if you have debris buildup.”
NADCA recommends at a minimum that an owner, principal, or key employee of a company become a certified ASCS. This individual must be a fulltime employee, be directly responsible for project management and should oversee all air duct cleaning projects. There is no limit to the number of company representatives who can become certified.

I live in Port Orange, FL. I purchased a double wide mobile home and was saddened to learn that the previous owners were HEAVY smokers! They did a good job “hiding” the smoke smell the day we viewed this place. I did not have a home inspection done unfortunately. My question is: can duct cleaning remove the smoke smell from this place. The ceilings have been treated with Kilz and paint. I personally scrubbed down every wall, floor or surface. I also purchased a ODORFREE OZONE machine. It seemed to remove the odor for a short period of time but my friends are again complaining about the “smoke” odor in my home. The Ozone machine was $400 and I’m terribly upset that it didn’t clean the air as was promised.
The air duct system in your home is used to distribute conditioned air throughout the house. In a typical house, however, some portion of the air moving through the duct system is lost due to leaks, holes, and poorly connected ducts. This lowers efficiency, increases energy costs and makes it more difficult to keep the house comfortable.
If you think duct cleaning might be a good idea for your home, but you are not sure, talk to a professional. The company that services your heating and cooling system may be a good source of advice. You may also want to contact professional duct cleaning service providers and ask them about the services they provide. Remember, they are trying to sell you a service, so ask questions and insist on complete and knowledgeable answers.
Ok what you said is true but in most cases ducts are in a duct flex format, and knowing that the dust in people’s flex duct is just surface dust, any real debris that are in the duct itself will result in very little to no air flow which will keep your unit from performing properly, but if it is true allergy reasons then replacing your duct system is better for overall better air quality, plus if you do pay attention to the warranty on flexible duct is that it only has a 10 year warranty and typically only lasts for 20 years so do your research before having a duct cleaning, and to add one more thing if your duct work is completely metal and you can’t see visible insulation then your duct on the inside has insulation inside of it, if you replace that with duct work that is clean metal on the inside and wrapped with insulation on the outside then it will further reduce the air bourne fiberglass and dust.

Air pollutants are 4 to 7 times higher INDOORS than outdoors! We spend 80-90% of our time inside, increasing the risk for allergies, asthma, breathing problems and lung damage, especially in the young and elderly.
Typically, air filters are either built into the heating and cooling system (whole-house filters) or are freestanding units that can be placed in individual rooms (portable filters with self-contained fans).
This is really well written & helpful. Just to make sure: so to clean your return register, you don’t need to shut the power off? I wouldn’t think so either, mine looks like yours, just a space under the hvac cabinet, no electric element seen. Thanks.
Cesar and Dennis were very professional in my home and did well with the job. They kept me in the loop the entire process by showing pictures of the vents and explaining everything. I feel bad they had a long day since my home was the last job of the day so I gave them a pop for the road! Good job!
It’s simple: over time as air is processed by the handlers and blown through the ducts, they will accumulate build-up. This happens anywhere, from a pristine office to less pristine industrial buildings. This buildup can lead to clogged HVAC vents, decrease the efficiency of the system, and even strain or damage the main unit, since it has to work harder to pump air through a dirty, clogged up system. This is a situation where spending a little now to keep your duct system clean can save a lot later.
Don’t Get Fooled: Keep in mind that intake ducts (room ducts that return air to the heating/cooling unit) are likely to be dirtier than supply ducts (which deliver conditioned air from the HVAC unit), since they often don’t have filters. Make sure any “before-and-after” photos are of the supply ducts, where it’s most important that the air is clean.
If someone in your family suffers from asthma or allergies, then again it is important to use a high-quality air filter and replace your ducting with a new, clean system.  My wife suffers from asthma, so I want to emphasize that I am honestly not trying to push unnecessary work on you.  Besides, what are the chances that you are even in our service area of Santa Clarita or Southern California?  If someone in your family suffers from Asthma or severe allergies, I’d replace your air conditioner and your ductwork, use a high quality air filter, and follow the additional advice in this article: How to Reduce Asthma Symptoms and How Your Air Conditioner Can Help.
lo everyone. I read your Experience. I can say, with good reason since i m an authorized technician of air duck cleaning, that Angie is absolutely right. in order to do a proper cleaning of the ducts serve the means and the proper time. usually for a normal house with a single system the amount payable is between 350 and 550 dollars and the time goes by dirt inside but always not less than 2 hours to clean everything. I regard cupon I can tell you that some are valid and offer the right price for the performance. I also read mold in ducts, before we tell the customer that there is mold perform a test that is analyzed in the laboratory and only after 3 days, with the result of the analysis of paper, inform risk and if the customer is okay proceed with the sanitation of the duct with certified products of the highest quality, just think that the product that we use costs 55 dollars a gallon. but I’m not here to make me adverts, I feel sorry for people who have had bad experiences, I personally love my job and I try to always do it in a proper manner.
Well, I had the cleaning done. The handler is definitely much quieter. It was explained to me that with the coils clean, the condensation will be able to sweat off instead of sticking to the dust and dirt, therefore the humidity (lots of humidity in florida) will be removed better. I feel as if it was worth it, but, I will definitely change that filter every weeks or so from now on. I don’t want to pay that cost again.
I did the $49.00 Groupon they just left. Basiclly all they did was stick a shop vac type hose into the vent supply and one return. I also had the dryer done. the person in charge pointed to the main return inside my humidifier and said it needed cleaning. I explained that I was in facility maintaince and would deal with it myself. After that they finished the vac and didn’t try any other sales pitch. I should have read the reviews before I bought this wast of money and time.
The EPA says that indoor air is often many times more polluted than outdoor air. Many of these contaminants get stuck or even grow in the ductwork, possibly getting re-circulated into the air you breathe. According to the EPA, “Contaminated central air handling systems can become breeding grounds for mold, mildew and other sources of biological contaminants and can then distribute these contaminants through the home.”
Imagine being absolutely certain that you were providing yourself, your family and the guests in your home with clean and high-quality indoor air each and every day. Using innovative techniques and state-of-the-art technologies, including brushing, air compression and vacuuming, the skilled technicians at Modernistic guarantee to leave you with a clean and better functioning air duct system.
If you’ve ever noticed black lines on the edges of your carpet, then your floors are not all that needs cleaning. This is called carbon filtration, which is a good sign that it’s time to clean your air ducts. Over time, dust and grime collect in your ductwork. When your heating and cooling system blows air through your vents, this dirt comes out with it, often gathering on fibers in your carpet and upholstery. A true whole-home cleaning includes your ductwork, which means cleaner air.
Our air duct sealing service is designed to locate and seal all of the holes and gaps in your air ducts that have formed over the years. This helps prevent dirt, dust, debris and ambient air from entering your system and decreasing its energy efficiency.
I’m having my duct work cleaned this Saturday. Have a coupon for $49 through Amazon. Job normally $249. Had my basement remodeled about 18 months ago. The contractors were very thorough at blocking the vents, as far as I can tell. The offer is for HVAC and dryer vent cleaning. My house is 11 years old. I figured, $49 is not much. I appreciate your tips on not getting talked into any additional service, not to use solvents to clean, the certification information and before and after pictures. Very useful and I’ll be sure that all I spend is the $49 for the voucher.

Jeremy – I allow all comments. Particularly ones like this because it gives me the opportunity to educate people. First off, if you really read the article, I clearly state this is a pretty good way to go if you don’t have the money for professionals. I’m guessing you’re a duct cleaner and don’t want me showing people a nice alternative that will save them money and improve their air quality far more than doing nothing. My articles are not aimed to help or hurt anyone’s business…only to help people who can’t afford such services to do the best they can to help themselves enjoy these luxuries when it’s within their ability to do so. I stand by every word in this article. With over 20 years in HVAC from loading trucks to currently running large commercial projects and everything in between, I think the professionals are already on it. Thanks for reading…or kind of anyway.

“air duct cleaning business _is air duct cleaning worth it”

I am very satisfied with the service I received the other day. The tech was great, polite and it seems like he knew what he is doing. I came across Dallas Air Duct Cleaning online and I a, glad I did. They cleaned my air ducts and did a very good job. I really recommend them and will use them in the future. Thank you
Sneeze. Cough. Wheeze. That’s what the home of an allergy sufferer sounds like around the clock. In Dallas, where allergens are prevalent nearly all year, it’s usually advisable to have routine air duct cleanings. People who have lung conditions and breathing difficulties, including asthma, can benefit from frequent cleanings because they help to prevent the spread of contaminants.
Well, if it’s just a piece, I’d throw it away. It’s likely a scrap piece that’s been in there longer than you may have realized and in your cleaning, worked it’s way to visibility. Unfortunately, much debris found in duct is from construction and people using the duct as a dustpan. If you don’t see any parts missing or holes in the ducting, then just toss it and know that they’re that much cleaner.
Vacuum the condenser fins with a soft-bristle brush attachment. The metal fins are delicate; avoid bending them. Clear away weeds, grass and other debris that block airflow through the coil. You often have to unscrew a protective metal case and lift it off to get at the condenser fins.
Open the blower compartment (with the power turned off) and lubricate any accessible ports on the blower motor with electric motor oil. Many newer blowers don’t have ports, or if they do, they’re inaccessible. Vacuum up any dust that has collected in the compartment.

Hi I clean air ducts cleaning in Wichita,KS and it’s true you get what you paid for… and I’m sorry I have to pay for my own gas, if my vehicle breaks down, I have to pay for it… I’m sorry I only get paid comission, I do have to eat, sleep, wash my clothes, but if you buy a coupon and you just wanna do the basic, that’s fine. Like the old saying goes “time is money!!” It’s the sad truth. But of you do spend some extra money believe me I will do my very best to make sure your happy. Every single thing I have read are negative what about the positive, I am a person that takes GREAT PRIDE in what do.
Violet Shrop – Thank you and no. You don’t want the power off while cleaning registers…you want the fan running. Now once you get to the furnace itself, at the end and you’re ready to change the filter and wrap up…yes. Turn off the power.
**Do they clean the Air Handler Unit or Furnace? The most important part of your HVAC system is the Air Handler Unit. Will the company you call clean the air handler unit? (Blower, coils, insulation, drainpan)?
Helpful information. Thanks. I wanted to add, I cut a good length from an old garden hose,inserted inside my vacuum hose and duct taped it. It extended the reach further in a tight space. Pulled out a gruesome amount of dog hair. Thanks again.
While you consider having your air ducts cleaned, it is a good idea to take a look at your dryer vent. If your dryer vent is clogged, you could be losing energy efficiency. Worse yet, you could be increasing the risk of a house fire. Having your dryer vent professionally cared for costs about $130 on average, and could save you a bit of money and a lot of headaches in the future. For more information on the benefits and cost of having your dryer vent cleaned, take a look at our comprehensive cost guide.
And if you have flex duct and/or fiberglass ductboard in your home- the last thing you want is a big brush or anything abrasive running through it. Even high-pressure air can erode ductboard so I wouldn’t clean it with anything. If it becomes contaminated, get rid of it and install real ductwork. If your ductwork is accessible in the basement – the best thing to do is take it down and manually clean it if it’s full of junk. It’s not going to cost a nickel more to do that than to pay $500-1000 for a ‘duct cleaning machine” AKA big blower and vacuum – to do the job.

I am reading theses emails from home owners and HVAC Duct Cleaning Companies. My Advice is Simple. In NC where I live and work, the air duct cleaning Industry is unregulated. There are less then honest companies selling their services every day – even on Angie’s List! I know – I own and operate a HVAC restoration company and see the scams every day!
Indoor air pollution is a hot topic these days and like every new industry, everyone is trying to get their piece of the pie.  Air duct cleaning is just one part of a broader industry aimed at increasing indoor air quality and promoting good health.  Duct cleaning is a service provided by some companies who utilize vacuums, brushes and chemical cleaning compounds to scrub the inside of your air conditioning ducts and HVAC coils, including supply and return air ducts, heat exchangers and evaporator coils.  The claim is that this will increase the health of you and your family by decreasing the number of contaminants in your air.  If we are being completely objective, however, I think it is important to point out at this point that according to the CDC, there is no evidence that duct cleaning increases your health.  More from the CDC can be found under: CDC – Air Duct Cleaning.

Each one of our technicians is trained to be a specialist in air duct cleaning and dryer vent cleaning business. We’re devoted to our customers and an excellent customer service is extremely important to us.
He proceeded to clean each heat register by removing the grille and blasting it with an air pressure hose toward the duct opening thinking that the dust would magically be sucked inside. In one room this caused a ceiling smoke detector to go off because the excess dust fooled it into thinking there was smoke. I put my hand in front of a register he wasn’t working on and could hardly feel a suction. Although we discussed how I open and close damper doors, I realized later that he never checked, opened or adjusted them during the cleaning. He could have closed all but the one he was working on in order to increase suction results. His next step was to blast air into the duct and then attach a “squid-like” device that slapped around inside the duct as far as he could reach. This is important! In a newer house, ducts have long straight runs from the furnace. In older houses like mine they can turn and twist. In fact, the duct we have a problem with runs straight up from the basement inside a wall and turns 90 degrees into a soffit for three feet then into two 90 degree turns to get into the floor joist area for another two feet and finally a 90 degree turn up to the second floor register. When he cleaned this one he could only get three feet into the register with the hose or squid because of the turns. That was the case with most. Hardly what could be described as a decent cleaning.
Portable ion units are similar to whole-house electronic filters in that they both put an electrical charge on particles. In a whole-house system, the particles of dust and pollen are charged as they pass through the unit, then captured on an oppositely charged collector plate. Portable ion filters, which operate without fans, send streams of negative ions directly into the air. Charged airborne particles are then attracted to a collection rod in the unit (which needs occasional cleaning), or with some models allowed to land on surfaces in the house (where dusting removes them from the room).

As a by-product of the ionization process, these types of units may produce trace amounts of ozone, a lung irritant. (Ion air filters should not be confused with ozone generators, a different type of air filter that relies on ozone to clean the air and is not recommended by the EPA or the American Lung Association.) Ion filters are considered safe if they release less than 50 parts per billion of ozone, the government’s threshold. But even smaller amounts could bother people with asthma or other breathing disorders. If you’re considering a whole-house or portable electronic filter, check the product specifications to make sure it does not exceed safe levels for ozone emission.
As is customary with credentialing practices, NADCA worked with independent test development experts and industry professional Subject Matter Experts (SMEs) engaged in the practice of HVAC system cleaning to perform a job analysis for the ASCS certification. The job analysis ensures the credential reflects the most current practices in the industry and properly reflects the knowledge, skills and abilities required for cleaning and restoring HVAC systems.
#3 The ONLY time Duct cleaning is needed is when the home had a fire, Bad roof leak on to FIBERGLASS ductwork or house sat vacant for many years with out the air running. And its better to replace than to do “abrasive” duct cleaning. If the duct cleaning has a rotating brush it will remove part of the glue that is holding the Fiberglass in the ducts together, PERIOD no matter how much the say it don’t because the brush is soft.
Find out whether your ducts are made of sheet metal, flex duct, or constructed of fiber glass duct board or lined with fiber glass since the methods of cleaning vary depending on duct type. Remember, a combination of these elements may be present.
Our professionals are IICRC trained and certified by the American Drying Institute. We utilize truck-mounted duct cleaning equipment that dislodges dirt and other debris. Then we use a high powered vacuum with sixteen 10-foot bags that take up the entire back end and allow for maximum airflow at all times.

I will have to wait and see if the the duct cleaning does make a difference. I would also prefer if the contact person would explain in detail all the possibilities of what extra expenses or extra work might be recommended. I trusted the technicians’ knoledge, but did not know if all that was recommended was truly necessary.
Get several estimates, and be sure you understand the specific work covered by each company’s quote. Ask about the service providers’ training and experience. If disinfectant spraying is recommended, ask for a clear explanation of the pros and cons of this treatment in your particular circumstances. Request and check references, and ask if the service provider holds any relevant state licenses. See if there are any complaints with the Better Business Bureau[9] .
If you have someone who smokes indoors, cleaning your ductwork is not the answer.  Your ductwork itself is non-porous and will not retain odors.  It is actually the dust in your ductwork that is retaining the odor, so using a quality air filter will again solve this problem before it begins.
We hired Mr.Duct to clean our dryer vent. Ivan, our technician, was prompt, courteous, and performed a thorough cleaning of our dryer system. I will recommend Mr.Duct to anyone and use them again ourselves!
What if you just moved into a new house but the air conditioner is not due for a replacement?  This is the only circumstance in which I would consider having your ducts cleaned.  I would also recommend that the cleaner you choose be an HVAC contractor as well so they can check your ductwork for leaks.
If no one in your household suffers from allergies or unexplained symptoms or illnesses and if, after a visual inspection of the inside of the ducts, you see no indication that your air ducts are contaminated with large deposits of dust or mold (no musty odor or visible mold growth), having your air ducts cleaned is probably unnecessary. It is normal for the return registers to get dusty as dust-laden air is pulled through the grate. This does not indicate that your air ducts are contaminated with heavy deposits of dust or debris; the registers can be easily vacuumed or removed and cleaned.
Interesting. Giuliano Cuete and Carlo Olcese have the exact same post about pretenders and being NADCA certified, word for word. So how do you become NADCA certified? And does that mean you are not a scam artist or a “blow and do” ripoff? hmmm, interesting. The EPA says that under normal conditions, a properly maintained system should NEVER need it’s ducts cleaned.
My best advice has always been that a proper duct cleaning is a valuable investment when moving into a home (new or old), after major renovations and if the ducts have never been cleaned before. It is unlikely that there will be increased air flow, as finding major blockage is unusual, but this will eliminate this as a possible concern if there are air flow concerns. It is also true that the “dust” that is cleared out will most likely never have been distributed through the house unless there has been some work done on the ducts. What is cleared out will be pet hair, toys, clothes, construction material, and biological material (small carcasses and/or feces). Once a proper cleaning is done a follow-up is rarely necessary, but up to the home owners discression.
2. If air quality is so important and duct cleaniliness is so uncertain, why not adopt doubling filtering; that is, in addition to the existing main furnace filter, add a filter at each air outlet. I understand replacing so many filters would be a burden, but air outlets can be designed for easy filter replacement. The builders and home design engineers should bear responsibility to provide good and low maintenance homes, rather than prioritizing on fancy or costly featuers for homes.
Professional cleaning involves getting the dust and debris outside, so they use outdoor ventilation equipment. It is so important that homeowners make sure the professional contractor is using good equipment then, as they could otherwise spread the spores into the home and further agitate sensitive family members. In the case of mold, a cleaner will only be able to tell you it is there, followed by needing an additional mold professional to come out and test or remove the mold. Air duct cleaning industries do not require state licensing, so make sure to check for a company with references.

If you have a forced-air furnace, you’ve already got a rudimentary air-filtration system: That matted-fiberglass filter that should be changed once a month. “You can’t change it often enough,” says This Old House plumbing and heating expert Richard Trethewey. When it clogs with dust, it stops working and overworks the furnace. In fact, those filters are designed to protect your furnace from large particles of dust, and while they might keep surfaces in your house a bit cleaner, they won’t block the microscopic particles that are most irritating to lung tissue. Pleated filters, which pack more material in the same amount of space, cost a few bucks more and do a slightly better job. By far the best pleated filters are electrostatically charged to attract allergens like pollen and pet dander. They cost around $15 and should be changed every two to three months.
I spent a lot of time reading all these posts and frankly I can’t believe the way some people think. 1. If there is dust and dirt of any kind in my HVAC system I want it out, the mentality that it can stay there and it’s fine is fulish as the system turns on and off microscopic particulates will move in and out of your living space and you will definitely breath them in. The air quality of your home or office will only be as clean as the system that produces it. We don’t not clean things simply because we can’t see them, it’s what we can’t see that can do the most harm. Dust will build up in a system fairly quickly and will get damp at times allowing mold to grow and mold releases spores without any movement as part of its defense meconisam so don’t tell me that when your system turns on it won’t blow the spores out into the living spaces of your home. A build up of dust will cause failures to your system over time, equipment that works harder to do its job will run hotter with more strain and this will lead to brake downs and until then the system will run less efficient then it should. The system was engineered to move a certain volume of air through a specific duct size, when that duct size starts to become narowed down with dust build up your system has to work harder to move that air this is why you will end up with a loss of efficiency and eventually breakdowns or failures. have seen systems develop a significant amount of dust build up in as little as two years, just look at how fast the filter gets clogged up and it isn’t all that hard to believe. As for all the scams that are out there they hurt the industry because people can’t decipher between them and the legitimate companies, BBB is helpful. Recommendations from HVAC contractors will be a good resource and a good company will provide a written estimate with a complete brake down of what they are going to do and why, most of which is comen sence once they explain it to you, then if you spend about 5 minutes watching them once they are set up you can see they are doing what they said they would do and let’s get real would you do a job that should take approx 3 hours per system for $29/$39/59 or something close to that, if you think you are going to get a good job from a comp that has to make money at that price you shouldn’t be mad at anyone but your self for trying to get quality work at a scam price. If it’s done right it will be very beneficial and depending on the size of your system and where you are in the world it’s going to cost you approx $300 to $600 per system large and or older systems may cost even more. Remember a quality job isn’t wasting money but a lousy job is, even if it’s only $29. I’d rather spend $600 on a quality job then $29 on a lousy job!! Good luck..
I was with you until you said avoid steaming cleaning or moisture, there is no way you can remove mold or any other type of biological without moisture. The best way to do this is in fact with a steamer using a commercial disinfectant and a non reactive odor remover so your home smells refreshed and not like a hospital . This is directly contradictory to your article.
When you hire someone to put up wallpaper or build a fence, it’s easy to see whether it’s a good job. But with services like air duct cleaning, there’s much more risk of fraud because the homeowner can’t easily check the work. A disreputable company may not have the proper equipment to do a quality air duct cleaning job, may overcharge you, may leave the ducts dirty or filled with debris and may even do costly damage to your home’s HVAC system. Some companies entice you with very low offers, such as $59 for a whole-house cleaning, then pile on extra charges. 
If you do have children or spouses who suffer from allergies or reactions to the air turning on, it might be an indication there is something in there making them react. They should speak with their doctors and then get a heating and cooling contractor out if it is recommended that airborne pathogens are the cause of their reaction.
My father started in the business of home comfort back in 1968, an I around 1986. We still don’t have a duct cleaning machine. I am sure there are always applications for all tools in this industry. However I missed where anyone talked about where dust even comes from……….We do not have these little dust machines sitting in a corner puffing out little clouds of dust….soooo where does it come from?
I know it has to have a new concentric venting system installed, I believe it needs new plenums ( mine are rusty but both of these require extra work , so someHVAC persons are saying I do not need either!! RED FLAG THERE. Also, it will need a new drain using PVCP ?? Piping run maybe two, depending on where my evep coil drain is conected (here in TN they use to run them in with the septic lines, now they cannot be run through that way), Lastly I am not where or what these things do beides hold water but I was told It needs a filter rack and new filter base safety pan. THATSSS it that is all I know about this stuff aside from the fact that nothing up there is to code thus far LOL. !!
I just had my Air ducts “cleaned”. The person who came to my house works for an air duct cleaning company who uses a professional vacuum. He said the company would charge me about $900 but he can do it aside on his own and charge me half of that. However, when he came over the house, he brought the rotary brush along with his domestic vacuum cleaner that it’s hose was about 5 feet long, I ask him that the wasnt strong enough to pull dust out, and he said, it’s similar to what companies use. I was in doubt and he didnt cover the vents so im thinking all dust must have come out from every air vents. Could this vacuum have taking the debris out of the air ducts? Or how can I myself find out if the inside of the air ducts have been cleaned and no debris is sitting there? I have dust all over my house.

I have lived in Calgary for quite some time now. When I first moved here I couldn’t stand the humidity levels. Its like a desert come winter. When I first moved into my new home, the house inspector insisted I have my furnace and ducts cleaned. I was very sceptical about duct cleaning to begin with. The company I hired came on time and were very respectable from the start. Before mentioning anything they asked me what my concerns were and what issues I was having. They were more concerned about addressing my issues then bringing anything non related up. I ended up going with this company and getting a humidifier installed a couple days later after the cleaning. Its been almost 4 years now that I have been here. The humidifier is working great and the difference is incredible. They took me around explained step by step what they were doing and the reasons they were doing it. With all those other companies out there, I am glad I found them at this site.
Hello, I read your comment and I know it was two years ago but I hope you see my message. I am trying to figure out what to do as I was told that there is some cat odor in the finished basement. I think with the air conditioning running that it may carry odor. The litter boxes are always kept clean. I wonder if odor can be trapped in the ducts, if Air Duct Cleaning could help, but it is quite expensive plus I’m concerned that it may not help. Please elaborate as to why you think it doesn’t work that well. Do you have any other advise? Did you work in the field of Air Duct Cleaning? Thanks so much!

Permit the application of biocides in your ducts only if necessary to control mold growth and only after assuring yourself that the product will be applied strictly according to label directions. As a precaution, you and your pets should leave the premises during application.
After the air duct cleaning service was complete, one of the men gave me a video inspection through one of the vents, and it was amazingly clean. The duct cleaning service took approximately 2 hours and they left no mess. Since the service, I have noticed very little dust inside my house.

“why do air duct cleaning -best air duct cleaning method”

I am an HVAC contractor. I have seen ducts so filthy that I did not want to breath the household air. Most systems are clean. An inspection cannot hurt. As a disclaimer I also own a duct cleaning machine.
For example, the evidence is weak that air cleaning devices are effective in reducing asthma symptoms associated with small particles that remain in the air, such as those from some airborne cat dander and dust mite allergens. Larger particles, which may contain allergens, settle rapidly before they can be removed by filtration, so effective allergen control measures require washing sheets weekly, frequent vacuuming of carpets and furniture, and dusting and cleaning of hard surfaces.
If you follow the above four steps, then you will never need to clean your AC ducting.  But what about the conditions recommended by the NADCA for the use of a duct cleaning company?  I’ll spare you my typical, cynical rant about the role that lobbyists play in swaying such organizations, and get to the list.  Let’s take a look at each:
I had someone out to clean my ducts last weekend. He took a blue bag up in my attic. He came back down in just a few minutes and said I had mold and he even showed me a picture of something saying it was mold but I couldn’t really tell. I refused his service to take care of the mold. He went back up in the attic for a little while and then came down. I never heard any sounds that he was actually up there doing anything. How do I know if he actually cleaned the air ducts?
5. Dirt and dust spread quicker in a home with dirty ducts. No matter how diligent you may dust and clean your home, fine particulate contaminates, including dangerous allergens, quickly flow from room to room to cover tables, smart phones, and children’s toys.
I agree, if you replace (or wash depending on type) your air filters regularly AND vaccum, then you probably don’t need the ducts or air coils cleaned. However, if you purchase a pre-owned home, and the previous owners did not regularly change the air filter or vaccum the home, then duct cleaning is worth the expense especially if you are sensitive to allergens. Especially if the previous owners had pets.
The EPA says that indoor air is often many times more polluted than outdoor air. Many of these contaminants get stuck or even grow in the ductwork, possibly getting re-circulated into the air you breathe. According to the EPA, “Contaminated central air handling systems can become breeding grounds for mold, mildew and other sources of biological contaminants and can then distribute these contaminants through the home.”
Bee’s Air Duct Cleaning is an air duct cleaning company. We are not carpet cleaners, who do air duct cleanings, or an HVAC company that offers air duct cleaning.

All of our technicians are family, as well as fully certified HVAC technicians dedicated to cleaning and maintaining your HVAC system. All of our trucks are outfitted with gas powered, truck mounted equipment with the power that is necessary for most commercial and residential jobs, as well as portable units that allow us to clean mobile homes, condos and buildings where access may be an issue. We will always have the right equipment for your job. The best tech’s combined with the best equipment, makes a Bee’s Air Duct Cleaning the Best Air Duct Cleaning!
7.         All supply vents are air-washed (at 180 psi) mechanically brushed, depending on the duct construction type and contamination. These tools are all remote-reaching, much like a plumber’s snake, and are ½” in diameter. Their use results in all contamination inside the vent and its duct work being moved into the main trunk duct line (the larger ductwork) where the vacuum is connected. Although the vacuum power is substantial, no harm is done to your duct system. Once this individual vent is finished, we apply duct mask and move to the next vent opening. Unless your system provides limited access, we do not vacuum up from each vent, as it is impossible to put a smaller diameter vacuum hose down a branch line and correctly clean through any vent opening. This is, however, something you can do with your store-bought HEPA-filtered vacuum cleaner.
The above information is informative, but did the data include the average size of the houses to go with the cost? It is hard to prove over pricing when you don’t have all the facts. Thanks for the information…I did learn something.
Please record the sales pitch you receive and post it up here. I’ve heard such stories about the coupon deals (either not showing up or hard selling upgrades), it would be great to hear how it goes for you.

“why is air duct cleaning important top quality air duct cleaning”

If you do what you can of the items above, you will have made a significant dent in the dust in your environment, and you will have done the best you can, short of calling a professional air duct cleaning company.
lo everyone. I read your Experience. I can say, with good reason since i m an authorized technician of air duck cleaning, that Angie is absolutely right. in order to do a proper cleaning of the ducts serve the means and the proper time. usually for a normal house with a single system the amount payable is between 350 and 550 dollars and the time goes by dirt inside but always not less than 2 hours to clean everything. I regard cupon I can tell you some are valid and offer the right price for the performance. I also read mold in ducts, before we tell the customer that there is mold perform a test that is analyzed in the laboratory and only after 3 days, with the result of the analysis of paper, inform risk and if the customer is okay proceed with the sanitation of the duct with certified products of the highest quality, just think that the product that we use costs 55 dollars a gallon. but I’m not here to make me adverts, I feel sorry for people who have had bad experiences, I personally love my job and I try to always do it in a proper manner.
Your cleaning service should involve all aspects of your duct work to maximize energy efficiency and air quality. This includes attending to the heat exchanger, blower, drain pan, plenum and coils as well. In the process, your service provider may find that you’re facing larger issues than debris and build-up. The professional may recommend having your furnace repaired if they notice, for example, damage to your heat exchanger or blower motor. Generally, a furnace repair costs between $130 and $500. They may also find that an A/C coil needs to be replaced rather than cleaned and would then recommend A/C repair.
9.         Once all vents are cleaned, we clean the main trunk ducts. We start at the far end of the trunk duct, away from the vacuum. Typically, all trunk ducts are mechanically brushed, air-whipped, and air-washed. The brushing and cleaning method is dictated by the construction of your duct system. Every home is different, so different tools are used to accommodate this. All the agitated material is caught in the air stream of the vacuum and sent down the line. If your main trunk duct is accessible, we typically install duct access every 15 to 20 feet to make sure we are removing EVERYTHING from the duct system.
Al and I just wanted to take a minute to say that John and Frank were great! Very professional and very personable. Because of these two gentlemen I will only use your company for any duct needs. I hope your company knows that the two of them is what gives …
No matter how thorough or efficient the air-duct cleaning process, it cannot possibly remove contaminants at a microscopic level. In some cases, customers may wish to have Oxine applied to the air ducts to complete the process. Oxine is an EPA-registered disinfectant and sanitizer that is effective against a wide range of bacteria, fungi, and viruses, and is recommended for its low toxicity. The technician applies Oxine to the air ducts with a fogger. Once the Oxine has been applied, the effects against harmful microorganisms last for up to two years.
New galvanized access panels or covers are installed over the openings created for the vacuum hose and sealed with aluminum tape if needed. Complete system test for running condition and complete work area clean up.
Once cleaning is complete and all components have been replaced, Cyclone Air Systems will not leave your home or office until it is absolutely certain that both the cooling and heating processes are operating properly.
Bee’s Air Duct Cleaning Denver could also be called an HVAC system cleaning.  Every one of our duct cleanings includes cleaning every part of your system that air passes through; the trunk, all supply and return vents and your furnace. This is a big difference between Bee’s and “the other guys.” The furnace is the central and most expensive element in your HVAC system. When the furnace is clean, it runs more efficiently saving you money on your monthly utility bills and it last longer which saves you from having to prematurely replace the furnace. When you call for a quote, furnace cleaning will be included in the price of your air duct cleaning. We also offer furnace and a/c maintenance services. with your duct cleaning, however, it is worthwhile to note that warranties on your furnace and a/c may be affected if you do not use the HVAC company that installed your system to provide routine maintenance.
Tyler – Yes. If the breaker to the furnace is off, you should be safe under normal circumstances. A simple voltage detector is always nice to have though to be sure. You just touch it to anything and if there is voltage, it will blink and/or beep. Only costs like $20 and is useful for many things. Thanks for reading.
As a homeowner and an owner of rental property I can tell you that the air ducts sometimes need to be cleaned. If you have had pets or anyone smoking in your home (even a visitor) for any length of time, having the ducts cleaned is really good idea. I had a tenant who did not smoke, but got married to a smoker more than year after moving in. When I realized someone was smoking I had them move out, but the smell was awful. I had the ducts cleaned and sanitized (it was a bit extra). The ducts were shiny like new afterwards. I left the windows open for a few days and we cleaned the place super clean and then replaced the carpets. The duct cleaning was worth every penny because the house looked, smelled, and felt new afterward. I plan to have my own house ducts cleaned again this year as we have two cats. We had them cleaned about 12 years ago and they found building materials in the ducts! If you move into a house that has never had them cleaned, it is good to do it. If you have allergies, clean the ducts to see if it helps. You never know what is in your ducts if you have never had them cleaned.
3-Put them all in the bathtub in warm water. Add a few drops of dish soap to the water and let the bubbles build up. The dish soap will help cut in grease and grime that has built up on the vents. Let the vents soak for about 10 minutes.
Specifically, do dryer vents (4″ round) need cleaning after 18 years? If a 4″ elbow equals 5′ of vent length, I have the equivalent length of 32′ from dryer to exterior outlet. I know lint can be a fire hazard.
Using our custom-built, high-powered vacuum trucks, we run a variety of high-pressure air tools through each duct, including brush systems and power whips. We utilize a high-powered vacuum system and a much larger vacuum hose that is 8 to 10 inches in diameter, pulling 12,000 cubic feet per minute.
Now it’s time to move inside. On the inside blower/furnace unit, find the evaporator coil door. You may need to remove some foil duct tape and take out a few screws or bolts. Inside, use a soft brush to dust off the coil, then spray the coil with commercially available no-rinse coil cleaner (available at home improvement stores). The spray will foam up and then drip into the drain pan. Clean out the drain pan with soap, hot water, and a little bleach. Then, pour a cup of 50% bleach/50% water down the drain. To keep the drain clear longer-term, place a commercially available drain pan tablet in the pan. This will inhibit future algae growth.
Inside your HVAC system, fine dust collects on air duct surfaces, vents, motors, and coils. Flakes of dead skin, hair, and pet dander catch onto the dust, and before too long this process creates a dense, mat-like environment where bacteria, mould, dust mites, and allergens can flourish. Air filters remove most of these from the air stream, but not for all parts of the HVAC system. That’s why it’s important to periodically check the condition of your air ducts to see if they could use air duct cleaning services
Get several estimates, and be sure you understand the specific work covered by each company’s quote. Ask about the service providers’ training and experience. If disinfectant spraying is recommended, ask for a clear explanation of the pros and cons of this treatment in your particular circumstances. Request and check references, and ask if the service provider holds any relevant state licenses. See if there are any complaints with the Better Business Bureau[9] .
Over time, algae and mold can build up and potentially plug the drain, so if the drain is either not flowing or flowing very slowly, it will need to be unplugged. A plugged drain can either cause damage by flooding onto the floor or, if the system is equipped with a drain float, cause the system to stop cooling in order to avoid flooding.
Chemical biocides are regulated by EPA under Federal pesticide law. A product must be registered by EPA for a specific use before it can be legally used for that purpose. The specific use(s) must appear on the pesticide (e.g., biocide) label, along with other important information. It is a violation of federal law to use a pesticide product in any manner inconsistent with the label directions.

“air duct cleaning reviews best air duct cleaning company”

Good article, but it fails to point out that leaky return-side ducts could be drawing dust and allergens into the duct system from the enclosed spaces in which they run, e.g. between walls, below floors, attic. So duct cleaning may only be a temporary solution. The homeowner can get a home energy audit — free in many states — to determine if they have significant duct leakage. An Aeroseal dealer may be able to effectively seal up the duct system without needing to tear into walls etc to get to the ducts.
This is very helpful…I appreciate the step by step information as well as the pictures. I will pass this along to my son-in-law as I think this is something he will use soon. As a matter of fact, he will probably use it at my house!!! Great job…congrats on the hub of the day too….
You have covered all necessary points on your blog. Dirty ducts blow dust, lint and other debris into every room of your home but sometimes you have to call professional for all duct cleaning services.
Ask potential air duct cleaning companies to provide you with a written checklist of exactly what they will do, and if you hire them, ask them to verify each task as they complete it. Qualified air duct cleaners will follow strict standards set by the National Air Duct Cleaners Association and should be happy to show you their credentials.
We hired Mr.Duct to clean our dryer vent. Ivan, our technician, was prompt, courteous, and performed a thorough cleaning of our dryer system. I will recommend Mr.Duct to anyone and use them again ourselves!
I would like to add that a lot of the dust is from your home and mostly found in your return vents and return ducting because as it pulls the air into the ducting from your house, along with the dust and moisture, some of it will gravitate towards the bottom of the ducting due to
Cleaning the air ducts in your home increases air flow within the system, helping to improve the efficiency of the HVAC system by distributing air throughout the house more quickly and with less effort. Regular cleaning of the air ducts also minimizes dust and debris entering the furnace, thereby helping to prevent clogging of the unit. ​
Because of the multitude of HVAC configurations and various scenarios that present themselves during an air duct cleaning service, technician experience can play a key role in the quality of service delivered. An experienced tech can gauge the quality of the previous duct cleaning work, appropriately assess the level of cleaning needed, and successfully troubleshoot difficult jobs.
4-7 Hour Process: When you have your duct cleaning performed by Four Seasons, a two man crew will come out to your home fully equipped to perform a thorough air duct cleaning. Where other less scrupulous companies may spend an hour or two cleaning your ducts, Four Seasons will spend at least 4-7 hours meticulously cleaning every section of your ducts.
While your furnace filter is designed to trap this particulate matter and prevent it from entering your air ducts, often particles still get through. The amount of particles your HVAC filter traps coincides with the quality of air in your home: the lower the quality of air, the more particles your filter will trap, and the more particles are likely to get through the filter. If these particles are allowed to build up, your HVAC system can become less efficient, having to operate longer to heat or cool your home. An inefficient HVAC system can result in inconsistent heating or cooling, higher utility costs, and expensive HVAC unit repairs (for instance, an A-coil or blower motor) if the problem is left unchecked. Air duct cleaning from Sears, which focuses on the dirt in your air ducts, can also boost the efficiency of a dirty HVAC system, cleaning out the particulate matter that can hinder HVAC effectiveness.
Sounds like your first hvac company was ripping you off. Ask your new company to go to your coil and see if there is a leak. If there isn’t the last company was just lining their pockets. If you have had ducts unhooked for a long time I would recommend duct cleaning, trust me I’m not a fan of duct cleaning myself. I have done hvac for 20 yrs. in GA. When I just bought a home built in 1996, we had all the ducts replaced immediately.
I have severe allergies and a son with asthma, we both were suffering with breathing issues after we moved into an older home in CNY. I called around and got a couple estimates for Air Duct Cleaning and went with Home Enhancement Solutions. Very courteous and professional, they cleaned every nook and corner of the duct work, all the vents and covers, the furnace and blower. They even showed me some of the stuff they pulled out, gross… but we are both breathing better. I will be having this done every year even though they said it may not be necessary to clean, but they will come back in a year and check for free. Highly recommend these guys to anyone that needs this done.
Ask the service provider whether they hold any relevant state licenses. As of 1996, the following states require air duct cleaners to hold special licenses: Arizona, Arkansas, California, Florida, Georgia, Michigan and Texas. Other states may require them as well.
High efficiency particulate air (HEPA) filters are in this category. Electronic air cleaners such as electrostatic precipitators use a process called electrostatic attraction to trap charged particles. They draw air through an ionization section where particles obtain an electrical charge. The charged particles then accumulate on a series of flat plates called a collector that is oppositely charged. Ion generators, or ionizers, disperse charged ions into the air, similar to the electronic air cleaners but without a collector. These ions attach to airborne particles, giving them a charge so that they attach to nearby surfaces such as walls or furniture, or attach to one another and settle faster.
Despite such anecdotal experiences, there’s no scientific evidence that regular residential air duct cleaning improves air quality, according to a 1997 brochure published by the Environmental Protection Agency. Laureen Burton, senior scientist in the EPA Indoor Environments Division, says that while the document is nearly two decades old, the science hasn’t changed and the agency stands by its recommendations.

Indoor air pollution is a hot topic these days and like every new industry, everyone is trying to get their piece of the pie.  Air duct cleaning is just one part of a broader industry aimed at increasing indoor air quality and promoting good health.  Duct cleaning is a service provided by some companies who utilize vacuums, brushes and chemical cleaning compounds to scrub the inside of your air conditioning ducts and HVAC coils, including supply and return air ducts, heat exchangers and evaporator coils.  The claim is that this will increase the health of you and your family by decreasing the number of contaminants in your air.  If we are being completely objective, however, I think it is important to point out at this point that according to the CDC, there is no evidence that duct cleaning increases your health.  More from the CDC can be found under: CDC Air Duct Cleaning.
No matter how thorough or efficient the air-duct cleaning process, it cannot possibly remove contaminants at a microscopic level. In some cases, customers may wish to have Oxine applied to the air ducts to complete the process. Oxine is an EPA-registered disinfectant and sanitizer that is effective against a wide range of bacteria, fungi, and viruses, and is recommended for its low toxicity. The technician applies Oxine to the air ducts with a fogger. Once the Oxine has been applied, the effects against harmful microorganisms last for up to two years.
When we think of pollution, we often think of smoking factories and hazy outdoor air. However, the U.S. Environmental Protection Agency (EPA) has found that levels of some hazardous pollutants in indoor air are as high as 70 times greater than in outdoor air. We are discovering that indoor air pollution causes allergies, asthma and even more serious illnesses.
