Your AC system goes the extra mile to make your home cool and comfortable, and the air filter is the secret to that hard work. So, just how often should you be replacing it?

The Rule of Thumb: Every 1 to 3 Months

Most standard air filters must be replaced every 30 to 90 days, but the best interval depends on some key considerations:

Allergies or Pets? Replace every 30–45 days.
No pets, no allergies? Every 60–90 days is just fine.
Vacation home or lightly used system? Every 3 months is sufficient.
Why Changing the Filter is Important

Better Air Quality – A clean filter attracts dust, pollen, and allergens more effectively.
Improved Efficiency – A clogged filter makes your AC do more work and costs more in energy.
Increased System Life – Less strain on your system equals less repair cost.
Quieter, More Consistent Temperatures – Unobstructed airflow keeps all your rooms cool.
How to Inspect Your Filter

Remove your filter and shine a light through it. If you don't see light passing through, it's filter-changing time.

Pro Tip: Set a calendar reminder or change your filter every time the season changes — it’s an easy way to stay on track.
