An outside unit that hums while the fan stays still is the call we get most in July in Glens Falls, 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 Glens Falls
Catching these issues early helps you avoid costly problems. Keep an eye out for the following clues:
- Puddles near the air handler or water stains on the ceiling beneath it
- Bubbling or hissing noises that point to a possible refrigerant leak
- The outdoor unit humming or clicking but the fan not spinning
- The system short-cycling every few minutes without cooling the house
- Warm or room-temperature air blowing when the thermostat calls for cooling
- Breaker trips or a burning odor at startup
- Ice on the refrigerant lines or a frozen indoor coil
- Rising electric costs paired with a sticky, uncomfortable house
Act Before It Gets Worse
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. If you notice any of these signs, call (518) 201-6286 for a prompt inspection.
