“is air duct cleaning worth it |what does air duct cleaning do”

Picture a stack of furnace filters about 8 inches thick and you get the idea of an extended media filter. These boxy units contain an accordionlike pile of filtration media, which makes them more effective than regular fiberglass filters. They require professional installation because the large filter holder must be plumbed into the ductwork. The price, including installation, ranges from $400 to $600; you’ll need to replace the $40-to-$60 filter every year.
This just tell us that we need to our air vent every once in a while. To prevent the worsening of an existing allergy. People non-sensitive will also benefit from this because they will not develop allergens from an air vent producing a clean and fresh air. Thank you for sharing.
8. Clean out blower compartment and return air boot. With the power off, you can remove the panels on the front of the furnace and access the blower compartment and the return air boot. Use your vacuum to sweep up the dust built up in the blower compartment and return air boot. This is where the great bulk of your dust will be. Since you’re in here, you should clean the furnace fan as well.
Portable air cleaners can be evaluated by their effectiveness in reducing airborne pollutants. This effectiveness is measured by the clean air delivery rate, or CADR, developed by the Association of Home Appliance Manufacturers, or AHAM. The CADR is a measure of a portable air cleaner’s delivery of contaminant-free air, expressed in cubic feet per minute. For example, if an air cleaner has a CADR of 250 for dust particles, it may reduce dust particle levels to the same concentration as would be achieved by adding 250 cubic feet of clean air each minute. While a portable air cleaner may not achieve its rated CADR under all circumstances, the CADR value does allow comparison across different portable air cleaners.
Case Paine was extremely professinal, clean, & a personable human being. Explained the process of duct cleaning and throughly answered all of our questions. Surely appreciate you sending us one of your Managers to clean our ducts. Mr. Paine definitely represents your company very well.
they comply with NADCA’s air duct cleaning standards and, if your ducts are constructed of fiber glass duct board or insulated internally with fiber glass duct liner, with the North American Insulation Manufacturers Association’s (NAIMA) recommendations.
Internal insulation provides better acoustical (noise) control. Flexible duct is very low cost. These products are engineered specifically for use in ducts or as ducts themselves, and are tested in accordance with standards established by Underwriters Laboratories (UL), the American Society for Testing and Materials (ASTM), and the National Fire Protection Association (NFPA). Many insulated duct systems have operated for years without supporting significant mold growth. Keeping them reasonably clean and dry is generally adequate. However, there is substantial debate about whether porous insulation materials (e.g., fiber glass) are more prone to microbial contamination than bare sheet metal ducts. If enough dirt and moisture are permitted to enter the duct system, there may be no significant difference in the rate or extent of microbial growth in internally lined or bare sheet metal ducts. However, treatment of mold contamination on bare sheet metal is much easier. Cleaning and treatment with an EPA-registered biocide are possible. Once fiberglass duct liner is contaminated with mold, cleaning is not sufficient to prevent re-growth and there are no EPA-registered biocides for the treatment of porous duct materials. EPA, NADCA and NAIMA all recommend the replacement of wet or moldy fiber glass duct material.
Remove dust and vacuum your home regularly. (Use a high efficiency vacuum (HEPA) cleaner or the highest efficiency filter bags your vacuum cleaner can take. Vacuuming can increase the amount of dust in the air during and after vacuuming as well as in your ducts).
My vent covers have lots of mildew. They look bad! I live in a very humid climate in a condo. The handyman here has offered to take those down, wash them, sand, & then spray paint them with a mildew resistant paint. He said that he will leave them off overnight to dry. I am wondering if this is safe to breath the AC blowing out into the open all night??. ! Guess it is better than the mildew!?
Most mechanical air filters are good at capturing larger airborne particles, such as dust, pollen, dust mite and cockroach allergens, some molds and animal dander. However, because these particles settle rather quickly, air filters are not very good at removing them completely from indoor areas. Although human activities such as walking and vacuuming can stir up particles, most of the larger particles will resettle before an air filter can remove them.
Vacuum frequently (weekly).  A lot of people think that their HVAC system is the only key to indoor air quality, but your air conditioner is just a part of an overall lifestyle that is required to be healthy.  Take a look at: How to Use a Vacuum Cleaner and Why.
HVAC systems carry harmful particulates and promote asthma, hay fever, and allergy symptoms. A clean HVAC system promotes a healthier indoor environment, which contributes to productivity, comfort and a sense of health and well being.

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.
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.
Minor problems with ducts can result in condensation inside the ducts. Insulation failure, a puncture in the duct wall, or a bad connection between components of the duct system can allow moisture to form. Moisture, combined with content in the dust, can result in mold growth.
These high-tech units, sometimes called electrostatic precipitators, are also incorporated into the ductwork. As air passes through, a high-voltage current puts an electrical charge on particles. At the other end of the unit, oppositely charged collector plates grab the particles like a magnet. Electronic filters work especially well on smoke particles too small to be trapped in media filters. One independent test found such filters worked about 30 times as well as regular fiberglass filters. (There is no industry yardstick for measuring the effectiveness of whole-house units, because performance is affected by a home’s blower and ductwork.) Unlike media filters, electronic filters never need replacing, but the aluminum collector plates must be cleaned in soapy water every few months. The process of charging particles, called ionization, may produce trace amounts of ozone, a lung irritant (see “Eye on Ions,” page 66). Electronic filters cost $600 to $1,000 installed and require a 120-volt electrical outlet.

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.
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.

Certified by the American Drying Institution, Carpet Tech offers free dryer vent inspections. Any responsible business owner would rest easier knowing they’ve taken a potential fire hazard into consideration and reduced their energy consumption.
4. Dust contains not only fine dirt, but also dead skin, pet dander, microorganisms from cat litter (toxoplasmosis), and other particulates such as pollen, mold spores, fungi, and even rodent feces. Left to contaminate your HVAC system, it can become a breeding ground for bacteria, mites, and other pests.
I have wondered if it was okay to tackle cleaning ducts yourself. I had them done professionally years ago, in a different house, and it was quite a job – but they had a rotor rooter sort of thing that went all through the duct work.
This article was very good. It should be noted that the EPA building in Washington, DC, was cited years ago as one of the worst “sick building syndrome” buildings. Wish you had mentioned about having people’s dryer vents cleaned since they can cause so many fires in homes. Most homeowners forget to check the air flow on the dryer vent. Our company, which cleans by NADCA standards, does both air ducts and dryer vents. Thanks again for keeping the public informed, especially regarding the cost of air duct cleaning…you get what you pay for…don’t be fooled by the lowest cost out there. Frequently these are bait and switch companies or will keep adding on features they say a customer needs until the price is so high it’s ridiculous.
When we bought our house we found a lot of debris including soda cans had fallen in the floor ducts which we found without grills. I have no doubt there is ample construction dust, moldering pet fur and perhaps a few mummified rodents in our ducts.
if your issue is mold, again correct maintanance of your filter will solve 95% of your problems. Those sensitive to allergies would be wiser finding out what is causing there allergies and addressing that problem than wasting hundreds on an air duct cleaning job.
I am just a homeowner and have absolutely no qualifications, but it seems pretty logical to me that a good cleaning every once in a while is just a good practice. It just seems like too vital of a component in a vital system to never clean.
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.
Everything went smoothly. One thing that would help would be for the payment to be clear before the visit. I did elect to have a deodorant application and I would have preferred to have the charge explained prior to the visit.

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.
The Environmental Protection Agency claims that indoor air has been found to be up to 70 times more polluted than outdoor air. Now consider, that most people spend between 60% to 90% of their time indoors…the facts can be quite alarming.
