A humming outdoor unit with a fan that will not turn is the classic summer service call in Poughkeepsie, NY, 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.
Warning Signs for AC Repair
Catching these issues early helps you avoid costly problems. Watch for these telltale signs:
- Puddles near the air handler or water stains on the ceiling beneath it
- Clicking or humming outside with no fan movement
- The system short-cycling every few minutes without cooling the house
- Vents blowing air that is barely cooler than the room
- Higher summer bills even though the house still feels warm and humid
- A hot electrical smell or a tripped breaker whenever the air conditioner kicks on
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- Frost or ice forming on the copper lines or the indoor coil
