An outside unit that hums while the fan stays still is the call we get most in July in Jeffersonville, IN, 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 to Call for AC Repair in Jeffersonville
Spotting the early warning signs lets you act before the problem gets expensive. Keep an eye out for the following clues:
- Cooling bills climbing while the house stays sticky and warm
- Warm or room-temperature air blowing when the thermostat calls for cooling
- Frost or ice forming on the copper lines or the indoor coil
- Hissing or bubbling sounds that suggest a refrigerant leak
- Water leaking around the indoor unit or from the ceiling below it
- A burning smell or repeated breaker trips when the AC starts
- Clicking or humming outside with no fan movement
- An AC that turns on and off every few minutes but never cools down the house
