A humming outdoor unit with a fan that will not turn is the classic summer service call in Camden, NJ, 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.

Warning Signs for AC Repair
Catching these issues early helps you avoid costly problems. Here are the most common indicators that it's time to call a professional:
- Puddles near the air handler or water stains on the ceiling beneath it
- Frost or ice forming on the copper lines or the indoor coil
- Bubbling or hissing noises that point to a possible refrigerant leak
- A burning smell or repeated breaker trips when the AC starts
- Room-temperature air from the registers even though the AC is running
- Rising electric costs paired with a sticky, uncomfortable house
- An AC that turns on and off every few minutes but never cools down the house
- Clicking or humming outside with no fan movement
Early Action Saves Money
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. At the first hint of a problem, call (856) 204-3434 for a fast inspection.
