A humming outdoor unit with a fan that will not turn is the classic summer service call in Pawtucket, RI, 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 to Call for AC Repair in Pawtucket
Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:
- Cooling bills climbing while the house stays sticky and warm
- An AC that turns on and off every few minutes but never cools down the house
- Puddles near the air handler or water stains on the ceiling beneath it
- Hissing or bubbling sounds that suggest a refrigerant leak
- Room-temperature air from the registers even though the AC is running
- A burning smell or repeated breaker trips when the AC starts
- Ice on the refrigerant lines or a frozen indoor coil
- Clicking or humming outside with no fan movement
Early Action Saves Money
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. If you notice any of these signs, call (401) 204-0654 for a prompt inspection.
