Why Is My AC Running But Not Cooling Properly?

Your AC can run without cooling due to a dirty filter, an incorrect thermostat setting, low refrigerant from a leak, a failed fan or capacitor, a weak compressor, or blocked/dirty condenser coils. Duct issues can also limit airflow. Our $179 diagnostic visit finds the root cause and is waived with any approved repair. We provide flat-rate, upfront pricing and 24/7 emergency AC service in Nassau County, including Garden City and Mineola.

Quick checks:

• Set thermostat to COOL, auto fan, and a lower setpoint.
• Replace a dirty filter.
• Clear debris around the outdoor unit.
