Why Is My Air Conditioner Running But Not Cooling Properly?

Your AC can run but not cool due to a dirty filter restricting airflow, a refrigerant leak, a faulty thermostat, frozen evaporator coils, drainage issues, or electrical malfunctions. We diagnose the root cause in Bellingham homes, carry common parts for same‑visit fixes, and verify cooling before we leave. Expect upfront pricing and a 2‑year repair warranty (4 years for Priority Plan members). Annual spring maintenance helps prevent these issues, including on ductless mini‑splits.

Quick checks:

• Set thermostat to Cool and lower the setpoint 3°F.
• Replace or clean the air filter.
• Open supply and return vents.
• Check for a tripped breaker.
• If ice is present, turn the AC off for 30–60 minutes.
