An outside unit that hums while the fan stays still is the call we get most in July in Slidell, LA, 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.
Signs You Need AC Repair in Slidell
Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:
- The outdoor unit humming or clicking but the fan not spinning
- Puddles near the air handler or water stains on the ceiling beneath it
- Warm or room-temperature air blowing when the thermostat calls for cooling
- Bubbling or hissing noises that point to a possible refrigerant leak
- Rising electric costs paired with a sticky, uncomfortable house
- Rapid on-off cycling that never brings the temperature down
- A burning smell or repeated breaker trips when the AC starts
- Ice on the refrigerant lines or a frozen indoor coil
