How often should you change your heating and cooling filters?

Quite often we’re asked what is one of the most important things that homeowner’s can do to ensure that their AC and heating system keep working year after year. The answer is simple, just remember to change the heating and air conditioning air filter. Replacing the furnace and return air filters is a critical maintenance to your HVAC system, which will keep it performing well all year long, as well as improving your indoor air quality. Did you know that studies have shown that indoor air pollution is one of the top five environmental health risks? For most homeowners, changing the air filter is not all that hard; however there are usually two challenges to actually completing this task:

  1. Knowing just how often to change your furnace or air conditioner filter.
  2. Remembering to change air filters when needed

When Should I Change My System’s Air Filters?

Most homeowners will change their air filters just before a new season, when they know that their equipment will be working full time. However, there are a few factors that can help you to determine how often you should change your air filter, here they are:

  • The type of filter your A/C system requires.
  • If you have pets in the home, you may want to consider replacing your air filters more frequently or choosing a type of filter that helps with dander.
  • How many people live in your home?
  • Do you leave your windows open?
  • Does anyone smoke in the home?
  • Where you live (urban/county areas)?
  • General air pollution in your area (construction taking place nearby, freeway, pollen, etc).

Most 1″ – 3″ air filters manufacturers recommend changing them bi-monthly, which is a great rule of thumb. However, this general recommendation may vary depending on some of the factors mentioned above, as well as your allergy tolerance. Meaning, you may need to change your air filter every month in order to improve your indoor air quality. On the other hand, if you’re in a remote area, or have a vacation home, you may replace your air filter a couple of times a year.
