What should I do if my AC is blowing warm air intermittently?

Intermittent warm air usually means airflow, thermostat, or refrigerant problems. Start with a few simple checks, then book a diagnostic so we can locate and repair the issue.

Quick checks:

  • Set thermostat to Cool and Auto; replace batteries.
  • Replace the air filter and open all supply vents.
  • Clear debris from the outdoor condenser.
  • If you see ice on refrigerant lines, turn the system off to thaw.
  • Check the condensate drain for clogs.

We service all makes and models and offer same-day, 24/7 AC repair.
