What Should I Do If My Air Conditioner Is Running But Not Cooling?

Start with a few quick checks, then book a diagnostic if cooling doesn’t return.

  • Set thermostat to Cool and Auto; replace batteries.
  • Replace a dirty air filter.
  • Make sure the outdoor unit has power and a clear, debris-free coil.
  • Check the breaker and the condensate drain for clogs or float-switch trips.
  • If ice is present, turn system Off and fan On for 2–3 hours. $89 HVAC Repair Diagnostic + Next Day Guarantee. Diagnostic Charge Waived With Service!
