Why Is My Air Conditioner Running But Not Cooling Properly?

Your AC can run without cooling due to thermostat issues, low refrigerant, dirty condenser coils, a frozen coil, or an inoperative fan. Our technicians diagnose these problems and perform checks like refrigerant pressure testing, condenser coil cleaning, condensate drain clearing, filter replacement, and a full system performance test.

Quick checks:

• Set thermostat to Cool and lower the setpoint.
• Replace or clean the air filter.
• Look for ice on the coil; if you see ice, turn the system off.
• Listen if the fan runs.
• Note short cycling (frequent on/off).
