How Often Should You Change Your Air Filter for Optimal Performance?

When it comes to keeping your home's air quality under control and your HVAC system running efficiently, changing your air filter is one of the most important tasks. In general, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days or 3 months. This may vary depending on the location of your home, if you have pets, and the age of your system and equipment. If you have pets in your home, you should consider changing the filter every 60 days or 2 months, and for households with multiple pets or people with allergies or respiratory conditions, we recommend changing the filter every 20 to 45 days.

Vacation homes or vacant homes that don't have much use can expect to change filters every 9-12 months. The more you use your home, the more often you need to change the air filter. Air filters quickly become clogged with debris, especially in the cooling season when air conditioners operate 24 hours a day. Not changing the filter can mean you'll face repair, higher energy bills, and a shorter air conditioner life.

In particular, air conditioning experts in Phoenix recommend replacing the AC filter every 1-3 months. That way, you'll keep the air conditioner running efficiently throughout the year. If you're a pet owner, you'll want to change your air filter every 2 months, especially when winter turns to spring and summer turns to fall. As a general rule, you'll want to replace your home's pleated air filters and heating filters every 90 days.

To keep air quality under control and your home clean, you'll want to replace the filter with a minimum interval of 2 to 3 months. If one of your household members is very allergic to dust, you should replace the air filter more often. Dirt and dust accumulated on the oven air filter will restrict airflow, causing heat to build up in the heat exchanger. When you can replace the air filters in your home, you'll move toward cleaner air in every room. Compared to other DIY home improvement projects, changing air filters is a quick and painless process that can be done in less than an hour.

If you live in a mild climate and only use your air conditioner or heater for a few hours a day, a filter could last the entire season or up to an entire year. Consequently, if you don't replace the AC filter regularly enough, it will become clogged with debris and dust particles which will reduce its efficiency and may even cause it to stop working altogether. Therefore, it is important to keep track of when it is time to change your AC filter so that you can ensure optimal system performance year after year.
