An outside unit that hums while the fan stays still is the call we get most in July in Vancouver, WA, 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 Vancouver
Catching these issues early helps you avoid costly problems. These are the signals our technicians see most often:
- An AC that turns on and off every few minutes but never cools down the house
- Ice on the refrigerant lines or a frozen indoor coil
- Cooling bills climbing while the house stays sticky and warm
- 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
- The outdoor unit humming or clicking but the fan not spinning
- Water leaking around the indoor unit or from the ceiling below it
- A burning smell or repeated breaker trips when the AC starts
