Change the air filter
A dirty filter makes the system work harder, cool less and freeze up.
Safety first: turn the power off before touching your A/C. Never open the electrical panel cover or the inside of the outdoor unit. If you smell burning, see sparks, or a breaker keeps tripping, turn it off and call us.
Steps
- Turn the system off.
- Find the filter: behind a return grille on a wall or ceiling, or in a slot on the indoor unit.
- Pull the old one out and check the size printed on its edge (for example 20x25x1).
- Slide the new one in with the arrow pointing toward the unit, the way the air flows.
- Write the date on the edge so you know when it's due.
Change it every 1–3 months. Every month if you have pets or work is going on in the house.
Call us if: The filter gets dirty in just a few weeks, or there's a lot of dust coming from the vents. (305) 842-0295
