An outside unit that hums while the fan stays still is the classic summer service call in Summerville, SC, 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.
When to Call for AC Repair in Summerville
Catching these issues early helps you avoid costly problems. Watch for these telltale signs:
- Water dripping from the indoor unit or showing up on the ceiling below
- Room-temperature air from the registers even though the AC is running
- Rapid on-off cycling that never brings the temperature down
- A burning smell or repeated breaker trips when the AC starts
- The outdoor unit humming or clicking but the fan not spinning
- Cooling bills climbing while the house stays sticky and warm
- An iced-over evaporator coil or frozen refrigerant lines
- Bubbling or hissing noises that point to a possible refrigerant leak
