A humming outdoor unit with a fan that will not turn is the call we get most in July in Brockton, MA, 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 Brockton
Catching these issues early helps you avoid costly problems. Watch for these telltale signs:
- A hot electrical smell or a tripped breaker whenever the air conditioner kicks on
- Rising electric costs paired with a sticky, uncomfortable house
- Water leaking around the indoor unit or from the ceiling below it
- Room-temperature air from the registers even though the AC is running
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- A condenser fan that sits still while the outdoor unit hums
- An iced-over evaporator coil or frozen refrigerant lines
- An AC that turns on and off every few minutes but never cools down the house
