In fact, the little independent research study performed on duct cleansing suggests that the procedure stirs up so much dust that it produces a larger problem than it resolves. To tidy ductwork, business place the duct system under negative pressureessentially linking a large, effective vacuum cleaner to several openings in the ductwork and sucking out loose dust and other particles.
Although duct-cleaning operations might firmly insist that duct cleaning is important for your health, the evidence does not support their claims (Air Duct Cleaning Company). While it intuitively makes sense to clean ductworkafter all, you dust and clean the rest of your home, so why unclean your ducts?the truth is dust that settles in your ventilation system normally stays where it is, not likely to end up being airborne unless disrupted.
Little research study has been done on the impacts of duct cleansing. U.S.- and Canadian-government research studies and health professionals who have actually investigated duct cleaning stop short of recommending against it, however neither do they back it as a regular procedure. The official advisory of the U.S. Epa (EPA) concludes: Duct cleansing has actually never been shown to really prevent health issues - Air Duct Cleaning - Dryer Vent Cleaning.
g., dust) levels in homes increase because of unclean duct. This is because much of the dirt in air ducts sticks to duct surfaces and does not necessarily enter the home ... Furthermore, there is no proof that a light amount of home dust or other particulate matter in air ducts positions any threat to your health.
After checking 33 homes in Montreal prior to and after duct cleaning, the study discovered no significant enhancement in air quality, and discovered that duct cleaning alone did not improve air flow or energy performance. In some cases, measured particle levels actually increased instantly after a cleaning. In other cases, particle levels decreased immediately after cleaning, but returned to previous levels within weeks.
Duct cleaning might be reasonable to you personally for that really factor: you may not desire to have your house air flowed through a duct passage that is not as tidy as the rest of the home.

The CMHC study called on a number of various duct-cleaning services. The companies were not warned they became part of a research study, and the scientists did not manage for time spent or methods utilized. The EPA study prescribed and managed techniques used on a smaller sized number of homes. While the duct-cleaning market argues that both studies have defects, no other research study has challenged the findings.
The American Lung Association's position on duct cleaning affirms the EPA's statement and recommendations, but includes: When illness are believed to be the result of biological contaminants or dust in indoor air, it is very important to first figure out that contaminated ducts are the reason for the illness and confirm that the ducts are, in reality, infected - Ductwork Cleaning - One Hour Heating & Air Conditioning.

Although not always part of their fundamental cleaning services, lots of duct-cleaning business often also tidy the heating and cooling devices (heat exchangers, cooling coils, condensate drain pans, fan motors, fan blades, and fan housings). Another questionable claim made by many duct-cleaning operations and their trade association is that dirty ducts and equipment overburden heating and cooling equipment, which loses energy.
However the page "Benefits of A/C Cleaning" on the National Duct Cleaners Association (NADCA) website stretches this benefit too far by stating: "According to the U.S. Department of Energy, 25 to 40 percent of the energy utilized for heating and cooling a home is wasted." That's misleading. Although much of the energy used to power cooling and heating equipment is undoubtedly lost, that waste is because of ineffective equipment, lousy insulation, leakages around doors and windows, and unsealed ductwork.
CMHC duct-cleaning study researchers discovered that when duct cleaners also cleaned the blower fan blades, there was a little reduction in air-borne particles. Cleaning the blower fan might likewise somewhat enhance your system's energy performance. The same applies for the evaporator coils inside your home's cooling system. Evaporator coils trigger condensation, dehumidifying the air before it circulates through your house.
Likewise, cleaning the collector pan (and the drain spout in the pan) below the coils guarantees that dirt does not construct up and get drawn into the system. It likewise avoids water, which can cause mold problems, from building up on and underneath the coils.

While there's little reason to hire a duct cleaner, here's one more reason to prevent them: Performed incorrectly, duct cleaning can do more damage than good.
( This describes the outcomes of the Canadian research study in which particle levels actually increased instantly after a cleaning.) Running brushes or using compressed air likewise risks breaking seals in the duct system, which can be especially problematic in the return-air part. The majority of forced-air systems are designed as closed loops, and leaks in the return-air circuit allow unfiltered air to be sucked from basements or attics, bringing with it dust and wetness.
Flexible coil-style ductsthe kind that looks like a Slinky toyare more vulnerable to being pierced. Ductwork produced from fiberglass-insulated materialwhich is cheaper than metal ductworkhas become more common in new houses. These ducts have fiberglass insulation on their interior surfaces. The fiberglass surface is sealed, but if a duct-cleaning company is not cautious, the cleaning can harm the insulation, loosening fibers that can end up being airborne.
org. In basic, consider duct cleansing only in response to specific recognizable issues. For instance, the EPA recommends having duct cleaned up only if there is visible evidence of: Considerable mold growth (but see below) Infestation of insects or rodents Significant deposits of dust or debris (if signs up were not sealed throughout a renovation job, for example) If anybody in your family has particular health issues, such as allergic reactions or asthma, consult your doctor initially.

The most likely offenders are the cooling system's evaporator coils, which your heating and air-conditioning contractorand most duct-cleaning companiescan check and preserve. Leaky return ducts can likewise introduce wetness (Duct Cleaning - Heating & Air). Once again, if you believe a mold problem, think about having a service business examine the duct system for leaks. If you suspectbut aren't surethat what you see is mold, you might be tempted to have it checked.
