An outside unit that hums while the fan stays still is the classic summer service call in Kent, WA, 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 Kent
Recognizing the warning signs early can save you time and money. Keep an eye out for the following clues:
- Cooling bills climbing while the house stays sticky and warm
- Frost or ice forming on the copper lines or the indoor coil
- A burning smell or repeated breaker trips when the AC starts
- Vents blowing air that is barely cooler than the room
- Puddles near the air handler or water stains on the ceiling beneath it
- A condenser fan that sits still while the outdoor unit hums
- Bubbling or hissing noises that point to a possible refrigerant leak
- The system short-cycling every few minutes without cooling the house
