A humming outdoor unit with a fan that will not turn is the classic summer service call in Mansfield, 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.

- Water leaking around the indoor unit or from the ceiling below it
- Room-temperature air from the registers even though the AC is running
- Clicking or humming outside with no fan movement
- Hissing or bubbling sounds that suggest a refrigerant leak
- Rising electric costs paired with a sticky, uncomfortable house
- Ice on the refrigerant lines or a frozen indoor coil
- An AC that turns on and off every few minutes but never cools down the house
