A humming outdoor unit with a fan that will not turn is the classic summer service call in Manhattan, NY, 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 the heat goes out, see Furnace Repair.
When to Call for AC Repair in Manhattan
Catching these issues early helps you avoid costly problems. Here are the most common indicators that it's time to call a professional:
- The system short-cycling every few minutes without cooling the house
- Hissing or bubbling sounds that suggest a refrigerant leak
- A hot electrical smell or a tripped breaker whenever the air conditioner kicks on
- Clicking or humming outside with no fan movement
- Cooling bills climbing while the house stays sticky and warm
- Warm or room-temperature air blowing when the thermostat calls for cooling
- Water dripping from the indoor unit or showing up on the ceiling below
- An iced-over evaporator coil or frozen refrigerant lines
Early Action Saves Money
