A humming outdoor unit with a fan that will not turn is the call we get most in July in Indio, 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 Indio
Spotting the early warning signs lets you act before the problem gets expensive. These are the signals our technicians see most often:
- Rising electric costs paired with a sticky, uncomfortable house
- Puddles near the air handler or water stains on the ceiling beneath it
- Frost or ice forming on the copper lines or the indoor coil
- Rapid on-off cycling that never brings the temperature down
- Clicking or humming outside with no fan movement
- 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
- Warm or room-temperature air blowing when the thermostat calls for cooling
Don't Wait for a Total Failure
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. At the first hint of a problem, call (760) 205-5185 for a fast inspection.
