How Often Do You Need to Clean Your Air Ducts?

Although indoor air pollution has existed since at least the Industrial Age, the significance of the problem has only recently attracted the attention of homeowners—and the press. In a recent article about indoor air quality, for example, The Baltimore Sun noted that most homeowners do not think about indoor pollution, but “poor indoor air quality in residential spaces is a serious problem.”

The Sun article includes a frightening fact: “The air within homes can be more polluted than the outdoor air in large, industrialized cities.” This statement may seem hard to believe, but a growing body of evidence (from the Environmental Protection Agency) supports this hard truth.

To combat indoor air pollution, the Sun advises eliminating dust mites, installing a central vacuum, mitigating moisture, and adding an air filter in the HVAC system. As a foundational step, too, G&G Indoor Air Services of Bucks County advises cleaning your entire HVAC system.

As Angie’s List notes in its article on air duct cleaning, the EPA and NADCA (National Air Duct Cleaners Association) “agree there's some benefit in cleaning debris from ducts, furnaces, central air conditioners and ventilation.”

The two bodies differ only on the recommendations. The EPA advises cleaning air ducts “when needed.” The NADCA advises cleaning air ducts every three to five years—or annually, if a family member suffers allergies or asthma.

Yet poor indoor air quality can harm any household member: “You may be having a bad air day everyday,” writes Web MD, which can affect “your health and the health of your family members.”
