A humming outdoor unit with a fan that will not turn is the call we get most in July in Eugene, OR, 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 Eugene
The sooner you notice these red flags, the easier and cheaper the fix. These are the signals our technicians see most often:
- Higher summer bills even though the house still feels warm and humid
- Frost or ice forming on the copper lines or the indoor coil
- Water leaking around the indoor unit or from the ceiling below it
- The outdoor unit humming or clicking but the fan not spinning
- Rapid on-off cycling that never brings the temperature down
- Bubbling or hissing noises that point to a possible refrigerant leak
- Breaker trips or a burning odor at startup
- Room-temperature air from the registers even though the AC is running
