Why Is My Air Conditioner Running But Not Cooling Properly?

Your AC can run but not cool if airflow is restricted, refrigerant is low, the thermostat is set wrong, the coil is frozen, or ducts leak. Our licensed and insured technicians handle AC repair, maintenance, and parts replacement in Novato and nearby cities.

Quick checks:

• Replace or wash the air filter.
• Set thermostat to Cool and lower the setpoint.
• Clear debris around the outdoor unit (at least 2 feet).
• Look for ice on lines or moisture around the air handler.
• Schedule a tune-up to test refrigerant and airflow.
