A humming outdoor unit with a fan that will not turn is the classic summer service call in Greeley, CO, 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 Greeley
Catching these issues early helps you avoid costly problems. Keep an eye out for the following clues:
- Hissing or bubbling sounds that suggest a refrigerant leak
- Vents blowing air that is barely cooler than the room
- Water leaking around the indoor unit or from the ceiling below it
- Higher summer bills even though the house still feels warm and humid
- An iced-over evaporator coil or frozen refrigerant lines
- A condenser fan that sits still while the outdoor unit hums
- A hot electrical smell or a tripped breaker whenever the air conditioner kicks on
- An AC that turns on and off every few minutes but never cools down the house
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Call (970) 602-4917 at the first sign of trouble.
