What would happen if you didn’t change your AC filter? It’s hard to believe such a small part could make a big difference in air quality and comfort, but it does.

Filters become a low priority due to a misunderstanding of what filters actually do. Standard HVAC filters are not intended to purify the air you breathe. Sure, the filter does trap some dust that gets sucked into the ducts. But most filters aren’t fine enough to trap pollen, dander, particulates and other allergens.

Your standard AC filter’s main job is to protect the AC unit itself from harmful things in the air. Once you change your AC filter, you make it much easier for the AC to keep you cool.

If you don’t change your AC filter, it will begin to fail. It will no longer be able to filter the air properly, letting dust and contaminants get into the AC. Dust jams the moving parts of an AC such as fan motors and valves. Airflow is restricted which creates a strain on the system.

When you change the AC filter each month during peak cooling season, you can save about 15% each month on utilities, plus prevent repair issues due to airflow restrictions.
