An outside unit that hums while the fan stays still is the call we get most in July in Lafayette, 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.

Signs You Need AC Repair in Lafayette
Catching these issues early helps you avoid costly problems. These are the signals our technicians see most often:
- Puddles near the air handler or water stains on the ceiling beneath it
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- Clicking or humming outside with no fan movement
- A hot electrical smell or a tripped breaker whenever the air conditioner kicks on
- Cooling bills climbing while the house stays sticky and warm
- Room-temperature air from the registers even though the AC is running
- Ice on the refrigerant lines or a frozen indoor coil
- An AC that turns on and off every few minutes but never cools down the house
