Why Is My Air Conditioner Running But Not Cooling Properly?

An AC that runs but won’t cool usually has airflow restriction or a refrigerant problem. Typical causes: clogged filter, dirty condenser/evaporator coils, blower or fan issues, low refrigerant, electrical faults, or duct leaks. We begin with a diagnostic, explain findings with upfront pricing, then repair and clean components. We offer same-day service and 36-point tune-ups for Tucson homes and businesses.

Quick checks:

• Replace the air filter.
• Set thermostat to Cool and lower 3–5°F.
• Clear debris around the outdoor unit.
• Check breakers and fully open vents.
