Indoor air pollution is a growing concern for homeowners, especially those who suffer from allergies. There’s much debate about whether dirty air ducts have a significant impact on the amount of dust in homes, and if cleaning the ducts can help prevent health problems. According to the EPA, a small amount of dust in the ducts is normal. Dust may also collect on return registers and isn’t necessarily a sign of badly contaminated ducts.
The EPA recommends that you clean air ducts only on an as-needed basis rather than routinely. Be wary of providers who recommend regular cleanings as part of your system’s maintenance, or those who make broad claims about the health benefits their service provides.
You may want to look into duct cleaning, however, if you can see mold growth inside the ducts. Keep in mind that cleaning might not get to the root of the problem. You must first determine what is causing the mold and correct it, or the mold will most likely return. Other potential reasons for duct cleaning include large amounts of dust coming from supply registers or vermin infestation.
Some companies will even offer to sanitize your HVAC system with chemicals. Make sure you’re fully informed before agreeing to the use of chemicals during the cleaning process. Visit the EPA’s Web site (EPA.gov/iaq/pubs/airduct.html) for more information about the process.
If you would like to have your ducts cleaned, ensure that the service provider is qualified. The National Air Duct Cleaners Association (NADCA.com) member search can help you locate a professional in your area. Before you hire a company, compare estimates and services from different providers in your area.
