While an airtight home is good for energy efficiency, it makes air quality a greater concern.

 “Due to improvements in modern window and door technology, today’s homes are more tightly sealed than ever,” explains Joe Frediani, co-owner of AWC in Millbrae. “While this is good for keeping conditioned air inside the home, one drawback is the home isn’t able to ‘breathe’ very well. As a result, all the air that gets circulated through the HVAC system tends to stay inside, which can make it challenging to maintain a high level of air quality.”

This lack of ventilation is further exacerbated by the increased use of heating and air conditioning in today’s world. “Between heating in the winter and air conditioning in the summer, the HVAC systems in most homes are running all the time,” says AWC co-owner Ron Frediani. “This increased use means a greater amount of airborne particles being circulated through the system, which results in more dust accumulating in the air filter and ductwork.”

With this in mind, consider the following steps for maintaining air quality in your home:

Change your HVAC filter regularly. Filters should be changed in accordance with the manufacturer-recommended interval. For example, if your filter is rated for three months, be sure to replace it every three months.

Upgrade to a better filter. Standard 1-inch fiberglass filters only provide a minimal amount of filtration, whereas high-grade, pleated filters do a better job of capturing dust, allergens and other airborne particles.

Have your air ducts periodically cleaned. A home’s air ducts should be professionally cleaned every two to three years, and more often if there are inhabitants with severe allergies or respiratory issues. Remember, effective air duct cleaning requires the right equipment and techniques, so be sure to hire a certified professional for the job.
