In truth, the little independent research carried out on duct cleaning suggests that the process stimulates so much dust that it creates a bigger problem than it resolves.

Little research study has actually been done on the impacts of duct cleansing.

Moreover, there is no proof that a light quantity of household dust or other particle matter in duct postures any danger to your health.
After testing 33 homes in Montreal before and after duct cleaning, the research study found no significant enhancement in air quality, and found that duct cleaning alone did not enhance airflow or energy performance. In many cases, measured particle levels really increased right away after a cleaning. In other cases, particle levels reduced instantly after cleaning, however went back to previous levels within weeks.
Duct cleaning may be understandable to you personally for that very factor: you might not want to have your home air circulated through a duct passage that is not as clean as the rest of the house. However, duct cleansing will not normally alter the quality of the air you breathe, nor will it considerably affect airflows or heating expenses.
The CMHC study called on several various duct-cleaning services. The companies were not made aware they belonged to a study, and the scientists did not manage for time invested or approaches utilized. The EPA study recommended and managed approaches utilized on a smaller variety of homes. While the duct-cleaning industry argues that both research studies have defects, no other research has challenged the findings.
The American Lung Association's position on duct cleaning verifies the EPA's statement and suggestions, however adds: When illness are thought to be the result of biological contaminants or dust in indoor air, it is essential to very first figure out that infected ducts are the cause of the health issues and verify that the ducts are, in reality, polluted - Air Duct Cleaning & AC Maintenance Services.

Another questionable claim made by most duct-cleaning operations and their trade association is that unclean ducts and equipment overburden heating and cooling equipment, which wastes energy.
But the page "Advantages of A/C Cleaning" on the National Duct Cleaners Association (NADCA) site stretches this advantage too far by specifying: "According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating and cooling a home is lost." That's deceptive. Although much of the energy utilized to power heating and cooling equipment is indeed lost, that waste is due to inefficient devices, lousy insulation, leakages around windows and doors, and unsealed ductwork.
CMHC duct-cleaning research study scientists discovered that when duct cleaners also cleaned the blower fan blades, there was a little decrease in airborne particles. Cleaning the blower fan may also somewhat improve your system's energy efficiency. The exact same holds real for the evaporator coils inside your home's cooling system. Evaporator coils cause condensation, dehumidifying the air before it circulates through your house.
Likewise, cleaning the collector pan (and the drain spout in the pan) underneath the coils guarantees that dirt does not develop up and get drawn into the system. It also avoids water, which can cause mold issues, from collecting on and underneath the coils.

While there's little reason to employ a duct cleaner, here's another reason to prevent them: Carried out improperly, duct cleaning can do more harm than good.
( This discusses the results of the Canadian research study in which particle levels actually rose immediately after a cleaning.) Running brushes or utilizing compressed air also risks breaking seals in the duct system, which can be specifically problematic in the return-air portion. The majority of forced-air systems are developed as closed loops, and leaks in the return-air circuit permit unfiltered air to be drawn from basements or attics, bringing with it dust and moisture.
Flexible coil-style ductsthe kind that looks like a Slinky toyare more susceptible to being punctured. Ductwork made from fiberglass-insulated materialwhich is more economical than metal ductworkhas end up being more typical in brand-new houses. These ducts have fiberglass insulation on their interior surfaces. The fiberglass surface is sealed, however if a duct-cleaning business is not mindful, the cleaning can damage the insulation, loosening up fibers that can end up being airborne.
org. In basic, think about duct cleaning just in action to specific identifiable issues.

The most likely perpetrators are the cooling system's evaporator coils, which your heating and air-conditioning contractorand most duct-cleaning companiescan inspect and maintain. Leaking return ducts can likewise introduce moisture (Affordable Duct Cleaning). Again, if you suspect a mold problem, think about having a service company examine the duct system for leaks. If you suspectbut aren't surethat what you see is mold, you may be lured to have it tested.
