A humming outdoor unit with a fan that will not turn is the classic summer service call in Abilene, TX, and the cause is usually a failed run capacitor. That inexpensive component starts the compressor and fan, fades for years without complaint, and then quits under peak load. It is far from the only suspect, though. Contactors pit and stop passing clean power, condenser fan bearings dry out, small refrigerant leaks drain away cooling capacity, and evaporator coils ice over when a clogged filter strangles airflow.

Warning Signs for AC Repair
Catching these issues early helps you avoid costly problems. Here are the most common indicators that it's time to call a professional:
- Breaker trips or a burning odor at startup
- Puddles near the air handler or water stains on the ceiling beneath it
- Ice on the refrigerant lines or a frozen indoor coil
- Rapid on-off cycling that never brings the temperature down
- Cooling bills climbing while the house stays sticky and warm
- The outdoor unit humming or clicking but the fan not spinning
- Hissing or bubbling sounds that suggest a refrigerant leak
- Vents blowing air that is barely cooler than the room
