Common problems we fix

  • System runs but isn’t cooling

  • Water leaking from the indoor unit

  • Blinking lights or error codes

  • Unit won’t turn on, or shuts off on its own

  • Strange noises or smells

  • Ice on the lines or coil

Quick checks before you call

  1. Make sure the remote or thermostat is set to Cool, with fresh batteries.

  2. Check the breaker for the outdoor unit.

  3. Rinse the indoor unit’s filters if they look dusty.

  4. Write down any blinking light pattern or error code; it helps us diagnose faster.

If none of that helps, or you notice burning smells, sparks or ice on the lines, turn the system off and call us. Don’t open up electrical components yourself.

How our repairs work

We diagnose first, explain what we found in plain language, and give you a clear price before any repair work starts. If a repair doesn’t make sense for an older system, we’ll tell you honestly.
