How Frequently Should I Change My A/C Air Filter?

If you’re like the average American, you probably spend 21 hours indoors every day and 16 hours inside your own home. If your A/C air filter is clogged and dirty, the health of you and your family may be suffering as well.

Changing your air filter is one of the best things you can do to keep your family healthy. Let’s look at the different factors that affect how often you should change your A/C filter, and how H&S Heating and Air Conditioning can help.

Air Filter Qualities

Some of the biggest factors which affect how often you should change your A/C air filter include:

  • type of air filter you are using;
  • overall indoor air quality;
  • number of pets in the home;
  • number of people in the home;
  • allergies of anyone in the home; and,
  • level of air pollution and construction around the home.

For basic 1-3″ air filters, manufacturers usually direct you to change them every 30-60 days. Here are some average air filter changing frequencies which might help you know how often you should change your own air filter at home:

  • single occupant home, no pets or allergies: 6-12 months
  • average family home, no pets or allergies: 3 months
  • average family home, any pets, any allergies: 1-2 months

If you notice any strange smells coming from your air conditioning system, you should contact a technician like H&S Heating and Air Conditioning right away.
