Why Is My AC Running But Not Cooling Properly?

Your AC can run without cooling due to restricted airflow, low refrigerant, incorrect thermostat settings, dirty coils, or duct leaks. Boulden Brothers offers same-day AC repair in many areas we serve, including Newark and West Chester. We use up-front, no-surprise pricing, and our VIP twice-yearly Bouldenization helps prevent breakdowns.

Quick checks:

• Set thermostat to Cool and lower 5°.
• Replace or clean the air filter.
• Open all vents; clear debris around the outdoor unit.
• Check the breaker and thermostat batteries.
• If lines are iced, turn AC off and fan on.
