An outside unit that hums while the fan stays still is the call we get most in July in Lee's Summit, MO, 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.

Recognizing the warning signs early can save you time and money. Watch for these telltale signs:
- Rising electric costs paired with a sticky, uncomfortable house
- The outdoor unit humming or clicking but the fan not spinning
- Water dripping from the indoor unit or showing up on the ceiling below
- Rapid on-off cycling that never brings the temperature down
- Bubbling or hissing noises that point to a possible refrigerant leak
- A hot electrical smell or a tripped breaker whenever the air conditioner kicks on
- Frost or ice forming on the copper lines or the indoor coil
- Warm or room-temperature air blowing when the thermostat calls for cooling
