An outside unit that hums while the fan stays still is the classic summer service call in Collierville, TN, 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.

Signs You Need AC Repair in Collierville
Spotting the early warning signs lets you act before the problem gets expensive. Keep an eye out for the following clues:
- The outdoor unit humming or clicking but the fan not spinning
- Breaker trips or a burning odor at startup
- Puddles near the air handler or water stains on the ceiling beneath it
- Hissing or bubbling sounds that suggest a refrigerant leak
- The system short-cycling every few minutes without cooling the house
- Rising electric costs paired with a sticky, uncomfortable house
- An iced-over evaporator coil or frozen refrigerant lines
- Vents blowing air that is barely cooler than the room
Act Before It Gets Worse
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 (901) 749-8008 for a fast inspection.
