An outside unit that hums while the fan stays still is the classic summer service call in Bowling Green, KY, 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.
When the heat goes out, see Furnace Repair.

- Hissing or bubbling sounds that suggest a refrigerant leak
- A burning smell or repeated breaker trips when the AC starts
- Higher summer bills even though the house still feels warm and humid
- Clicking or humming outside with no fan movement
