Does cleaning air ducts really make a difference?

Jul 11

The science of air duct cleaning is still in its infancy. Therefore, it is difficult to give a blanket recommendation on whether or not you should have them cleaned in your home.

It has never been proven that duct cleaning can prevent any health problems. Studies have not shown that dirty air ducts cause an increase in particle (e.g. dust) levels in homes. This is because most of the dirt in the air ducts sticks to the duct surfaces, and doesn't necessarily get into the living space. Remember that dust from dirty air ducts is only one source of particles in homes. Indoor and outdoor pollutants can enter your home from both indoor and outdoor activities like cleaning, cooking, smoking, and just moving about. There is no evidence to suggest that even a small amount of household dust, or any other particulate matter, in air conduits poses any health risk.

What is air duct cleaning?

Indoor air pollution is a growing problem that has increased awareness and concern. Many companies offer products and services to improve indoor air quality. Most likely, you have seen an advertisement or received a coupon by mail. Or, perhaps, you were approached directly by a company to clean your indoor air ducts.

Duct cleaning is the general term for cleaning various heating and cooling system components, such as the supply and return ducts and registers. It also includes grilles and diffusers. Heat exchangers heating or cooling coils, condensate drainage pans (drip pans), fan motor housing, and fan housing. These components can become contaminated with dust, pollen, or other debris if they are not maintained and installed correctly. Moisture can increase the risk of microbiological growth, such as mold, and may result in spores being released into the living spaces. If these contaminants are inhaled, they can cause allergies or other symptoms. It is crucial that you confirm that the service provider is licensed and willing to clean your heating and cooling systems.

If you are unsure whether your air ducts need to be cleaned, it is worth looking into having them cleaned.

Deciding whether or not to have your air ducts cleaned

It is difficult to know the benefits and potential problems of air duct cleaning. Because every home is unique, it's impossible to say whether air duct cleaning would benefit your home.

Your household does not have any allergies or other symptoms. If you do not see any evidence that your air ducts are contaminated by mold or large amounts of dust (no mold growth or musty odor), it is probably not necessary to have them cleaned. As dust-laden air flows through the grate, it is normal for return registers to become dusty. However, this does not mean that your air ducts have become clogged with dust and debris. The registers can easily be vacuumed up or removed.

Other important considerations

It has never been proven that duct cleaning can prevent any health problems. Studies have not shown that dust and particle levels in homes are affected by dirty air ducts. This is because most of the dirt that can accumulate in air ducts sticks to the duct surfaces, and doesn't necessarily get into the living space. Remember that dust from dirty air ducts is only one source of particles in homes. Indoor and outdoor pollutants can enter homes from both indoor and outdoor activities like cleaning, cooking, smoking, and just moving about. There is no evidence to suggest that even a small amount of household dust, or any other particulate matter, in the air ducts poses any health risk.
