A humming outdoor unit with a fan that will not turn is the call we get most in July in Baton Rouge, LA, 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 Baton Rouge
The sooner you notice these red flags, the easier and cheaper the fix. Here are the most common indicators that it's time to call a professional:
- The outdoor unit humming or clicking but the fan not spinning
- Water leaking around the indoor unit or from the ceiling below it
- Higher summer bills even though the house still feels warm and humid
- An iced-over evaporator coil or frozen refrigerant lines
- Room-temperature air from the registers even though the AC is running
- Hissing or bubbling sounds that suggest a refrigerant leak
- Breaker trips or a burning odor at startup
- The system short-cycling every few minutes without cooling the house
