HVAC

The answer to 'when to service air filter' is that you should check and clean or replace your air filter every 1-3 months, depending on usage and environment. A clean air filter helps your HVAC system run more efficiently, improves indoor air quality, and extends the life of your equipment.

It's important to check your filter regularly, as a clogged or dirty filter can restrict airflow and cause your system to work harder, leading to higher energy bills and potential equipment damage. If you have pets, smoke, or live in a dusty area, you may need to change your filter more frequently.
