What Should I Do If My Air Conditioner Is Running But Not Cooling?
If your AC runs but isn’t cooling, try a few quick checks. Set the thermostat to Cool and lower the setpoint. Replace a dirty air filter. Clear debris around the outdoor unit and confirm its fan spins. Check the breaker and furnace/air handler switch. If you see ice on the lines or coil, turn AC Off and fan On to thaw, then call. Ongoing warm air often needs refrigerant checks, coil cleaning, or control calibration by our NATE-certified techs serving Pittsburgh and nearby.
