A humming outdoor unit with a fan that will not turn is the call we get most in July in Temecula, CA, 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 Temecula
The sooner you notice these red flags, the easier and cheaper the fix. These are the signals our technicians see most often:
- An iced-over evaporator coil or frozen refrigerant lines
- The system short-cycling every few minutes without cooling the house
- Cooling bills climbing while the house stays sticky and warm
- Water dripping from the indoor unit or showing up on the ceiling below
- A burning smell or repeated breaker trips when the AC starts
- The outdoor unit humming or clicking but the fan not spinning
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- Vents blowing air that is barely cooler than the room
Act Before It Gets Worse
