An outside unit that hums while the fan stays still is the classic summer service call in Schenectady, 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 to Call for AC Repair in Schenectady
Catching these issues early helps you avoid costly problems. Keep an eye out for the following clues:
- The outdoor unit humming or clicking but the fan not spinning
- 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
- Puddles near the air handler or water stains on the ceiling beneath it
- Warm or room-temperature air blowing when the thermostat calls for cooling
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- Breaker trips or a burning odor at startup
- Frost or ice forming on the copper lines or the indoor coil
