AC Not Cooling?

4 DIY Checks Before You Call

  1. Thermostat Settings – Make sure it’s set to COOL and at least 3 °F below the current room temperature.
  2. Air Filter – A clogged filter chokes airflow and can freeze coils. Replace if it’s more than 60 days old or visibly dirty.
  3. Outdoor Unit Airflow – Clear leaves, grass clippings, and pollen drifts at least 18″ around the condenser.
  4. Breaker Panel – Verify the AC breaker hasn’t tripped. Flip it fully off, then on, and wait five minutes.

Tip: If ice is present on the copper lines, turn the system OFF and switch the fan ON to thaw while you wait for a technician.

Call a Pro When You Notice:

  • Warm air continues after 15 minutes
  • System short‑cycles (on/off rapidly)
  • Ice returns after thawing
  • Buzzing, humming, or burning odors
  • Inside temp climbs 2 °F per hour or faster
