An outside unit that hums while the fan stays still is the classic summer service call in Cranston, RI, 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.
For winter breakdowns, see Furnace Repair.
Warning Signs for AC Repair
The sooner you notice these red flags, the easier and cheaper the fix. These are the signals our technicians see most often:
- Clicking or humming outside with no fan movement
- Hissing or bubbling sounds that suggest a refrigerant leak
- The system short-cycling every few minutes without cooling the house
- Ice on the refrigerant lines or a frozen indoor coil
- Water leaking around the indoor unit or from the ceiling below it
- Warm or room-temperature air blowing when the thermostat calls for cooling
- Higher summer bills even though the house still feels warm and humid
- A burning smell or repeated breaker trips when the AC starts
