For Healthy Air, Change Your HVAC Air Filter

How often do you need to change your HVAC air filter? Like the stovetop and refrigerator, the HVAC system is one of many household elements that require periodic cleaning and upkeep. Unlike the stovetop or refrigerator, though, the HVAC system is “out of sight, out of mind.” Despite its important role in the home, the HVAC system is often neglected—until the system fails.

Fortunately, routine cleaning and upkeep ensures HVAC efficiency—and efficiency is associated with multiple benefits, including reduced heating and air conditioning costs as well as improved indoor air quality.

Your home’s indoor air quality (IAQ) is an important determinant of your family’s health. In many cases, indoor air can be as polluted as outdoor air. The consequences are serious. As the EPA notes, “Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later.”

Fortunately, too, proper HVAC cleaning and upkeep is often as simple as changing the air filter. How often you need to change your air filter depends on several elements—all unique to your house.

Most environmental experts suggest replacing the HVAC air filters every three months. However, living in San Diego, a city with “bad air quality,” can change the equation. Some air filters may need to be replaced every month.

Your frequency of HVAC use can also change the equation—as well as your family size, any household pets, like cats or dogs, and daily activities like cooking, burning incense, or the use of common household cleaners, like Windex.

Periodic air duct cleaning is another simple intervention. HVAC experts suggest cleaning ducts every three to five years; or each year, if a family member suffers from asthma.

San Diego’s leading air duct company, G&G Indoor Air Services, sells two products to keep your HVAC system clean and pollutant-free: HVAC air purifiers and electrostatic filters. To learn more about our air duct cleaning services, call today.
