Why Is My Air Conditioner Running But Not Cooling Properly?

If your AC runs but doesn’t cool, the usual causes are a clogged filter, low refrigerant, dirty coils, a frozen evaporator, thermostat or control issues, blocked outdoor airflow, or duct leaks. Technicians in Dayton and Mason handle these exact problems with 24/7 emergency service and upfront estimates.

Quick checks:

• Set thermostat to Cool and lower the setpoint.
• Replace a dirty filter.
• Clear debris around the outdoor unit.
• Open supply/return vents.
