A humming outdoor unit with a fan that will not turn is the call we get most in July in Murfreesboro, TN, 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.

Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:
- Clicking or humming outside with no fan movement
- Water leaking around the indoor unit or from the ceiling below it
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- Vents blowing air that is barely cooler than the room
- Higher summer bills even though the house still feels warm and humid
- Breaker trips or a burning odor at startup
- The system short-cycling every few minutes without cooling the house
- An iced-over evaporator coil or frozen refrigerant lines
