AC not cooling? We find out why.
From a failed capacitor to a frozen coil, we diagnose air conditioning problems with real readings and explain the fix before we start.
Air conditioning problems we repair
Most AC failures happen on the hottest days, when the system works hardest.
Symptoms
- AC running but blowing warm air
- Outdoor unit not running
- Ice on the refrigerant lines or indoor coil
- Weak airflow from vents
- Water leaking near the indoor unit
- Breaker tripping when the AC starts
- Buzzing, humming or clicking outside
Frozen coil?
Turn cooling off and run the fan only to thaw it. Running a frozen system can damage the compressor. Ice usually means low airflow or a refrigerant problem, and both need a proper diagnosis.
How we diagnose an AC problem
Electrical
Capacitors, contactors, fan and compressor amperage measured.
Airflow
Filter, blower, coil and duct restrictions checked.
Refrigerant
Pressures, superheat and subcooling checked by a certified tech.
Performance
Temperature split confirmed after the repair.
