In June 2012, NADCA (The National Air Duct Cleaners Association) has officially released its position on this matter. “The EPA has not registered any products for sanitizing or disinfecting ductwork. Further, no fungicides are registered for use in ductwork,” states the position paper. “Therefore, any claims of sanitizing or disinfecting ductwork would require the use of a product in a manner inconsistent with its labeling.” As a general rule, the recommended method for cleaning duct work is not chemical application, instead, NADCA clearly states in its publication ACR 2006 that source removal is the best and most effective way to clean air duct systems. This position by NADCA does not mean that certain products do not have a use in HVAC duct systems, but instead states that any claims made that a chemical treatment will sanitize or disinfect the system are illegal as there are no EPA registered products that are labeled for such.

Therefore, if source removal is best, what is the recommended method of source removal. According to the ACR 2006, it is recommended that the air duct system be placed under negative pressure utilizing a negative air machine, either truck mounted, gas powered (outside,) or electric with HEPA filtration (inside.) Once the system is under negative pressure, the next step to an effective air duct cleaning is agitation of the air ducts. Agitation can be accomplished utilizing a variety of brushes (both handheld and auto-mechanical,) compressed air (fittings, whips, and other devices,) among other agitation tools.

DuctClean, a division of MoldStoppers, is a NADCA certified company that strictly adheres to the standards set forth by the ACR 2006. Although the EPA does not register a product for use in HVAC systems, it does register many products for use on hard, non-porous surfaces including metals. As such, DuctClean uses Benefect disinfectant as part of the air duct cleaning process. This product is registered by the EPA as a decontaminant suitable for disinfecting hard, non-porous surfaces including metals.

This is why it is very important to screen who you will choose to clean your air duct systems. Many air duct cleaners will recommend this as a method of cleaning. Although using a product as part of an air duct cleaning may be useful, any company claiming that it will sanitize or disinfect your air ducts using a chemical application only is breaking the law. When possible, only use a certified Air Systems Cleaning Specialist designated by NADCA. Always check a company against NADCA’s database at

Consumers Should Know The 12 Steps to a Proper Air Duct Cleaning

Air Duct Cleaning CompanyCleaning the air ducts in any building is a complex and time consuming job, especially to try to do alone. It’s easy, as well as cost and time effective to hire a professional company to clean our your air ducts. The process they use follows 12 steps, from start to finish.

Step 1. Before anyone even sets foot in the workplace, the air duct cleaners are subject to background checks, drug checks and extensive training. They’re specialists with the knowledge and experience necessary to clean ducts without a hitch.

Step 2. A good professional duct cleaning company outfits their workers with shoe covers, to absolutely guarantee that no dirt will be tracked through the building and no damage will be caused to floors. You can rest assured that when the workers leave, there will be no trace of their presence.

Step 3. The well trained technicians will fully inspect every aspect of the building’s HVAC system. This ensures that they know exactly what needs to be serviced. Your inspection and work will be customized to your building, and will address any problem that’s found.

Step 4. A high powered vacuum and negative pressure machines create the ideal atmosphere for dust collection and removal. Coupled with robust seals around intake and exhaust vents, this process means that every speck of dust is collected and disposed of, and not pumped back into circulation.

Step 5. By default minor disinfectants are used to wipe down and clean the system. If you choose, stronger EPA-approved disinfectant fogging can be used to fully cleanse the system. Nothing harmful will be left in the system.

Step 6. Duct cleaning involves more than just a vacuum effect. Powerful scrubbers are snaked through the ducts, dislodging and sweeping out caked on grime, oily dust and hair that collects over months or years. All of this is removed from the system and disposed of properly.

Step 7. Both before and after the servicing is done, infrared cameras are snaked through the ducts to show the state of the HVAC system. This way you can see the state of the ducts before the work is done, and can see how effectively cleaned they are afterwards.

Step 8. If the HVAC system is old and no longer up to standard, the trunk lines and plenums can be cleaned and access doors can be built into them, to bring the system up to code.

Step 9. Once the ducts are cleaned, full attention is turned to the furnace. Because dust can be kicked up into it during the cleaning process, it’s given a full cleaning inside and out. This includes the filter box, blower and combustion chamber.

Step 10. Any access holes created are sealed with doors created to current code. Floors are swept, all debris is removed, and the dust is properly disposed of. After this process, you should never be able to tell the workers were there.

Step 11. You’ll receive a detailed report of an air quality inspection performed while the work was being done. This includes the dust in ducts as well as possible mold issues and anything else found during the cleaning.

Step 12. If for some reason you’re not completely satisfied, there’s a money-back guarantee. Just let the company know, and you’re good to be reimbursed.

Many people will take the time to clean practically everything in their home or business, but few people actually get a professional air duct cleaning.

There are many reasons that you should get your air ducts cleaned. The first primary reason is that they likely have never been cleaned before. Over time, dust and debris can settle in the ducts and this can eventually lead to a lot of health and financial problems. Families that have allergy sufferers really need to make sure that a professional HVAC employee comes to clean out the ducts at least once per year. The amount of dust and dander that can settle in the ducts can be quite substantial. By the way, if it looks dirty than it probably is.

When the air gets circulated 5-7 times a day, the build-up of these contaminants can cause major problems. Your air quality will not necessarily be bad, but anyone that really suffers from allergies or autoimmune disorders may be negatively affected.

Another key reason to have clean air ducts is the amount of money you will save in energy costs. The cleanerallergy from dirty air ducts your system is, the more efficiently it will run.

This means that you are paying more money to heat and cool your home. The best thing to do is to simply get the air ducts cleaned out. This will save you money in the long run. The United States Department of Energy feels that most homes waste 25-40 percent of the energy that it takes to heat or cool a home. Those percentages increase for businesses. Much of that wasted energy and money can be saved by having a professional clean the air ducts throughout your home or business.

It is of the utmost importance to keep your entire home or business running efficiently and effectively. The air ducts are like the lungs to your home. You need them to work as effortlessly as possible. The creation of debris and dust in your home will affect your HVAC system.

Business owners should do the same, because they are constantly dealing with patrons that want to breathe good clean air.
