Why Is My AC Running But Not Cooling Properly?

Your AC can run but not cool if airflow is restricted, refrigerant is low, or controls are off. Common causes include a clogged filter, dirty coils, a blocked condensate drain, failing capacitor or fan motor, thermostat miscalibration, duct leaks, or a refrigerant leak. We diagnose and fix AC, heat pump, and mini-split issues, including coil cleaning, drain clearing, refrigerant checks, and motor/capacitor repairs. 24/7 emergency service is available in Phoenix and Tempe.

Quick checks:

• Replace or clean the air filter.
• Set thermostat to Cool and lower 3–5°F.
• Clear debris around the outdoor unit.
