Most AC breakdowns in Rochester Hills start with a small part: the run capacitor. It helps start the compressor and condenser fan, loses strength slowly over the years, and tends to give out on the hottest afternoon, which is why so many service calls begin with an outdoor unit that hums while the fan sits motionless. Other frequent culprits include contactors with pitted, burned points, fan motors whose bearings have run dry, slow refrigerant leaks that steadily rob capacity, and evaporator coils that turn into blocks of ice once a dirty filter chokes the airflow.

Warning Signs for AC Repair
Recognizing the warning signs early can save you time and money. Keep an eye out for the following clues:
- Bubbling or hissing noises that point to a possible refrigerant leak
- An AC that turns on and off every few minutes but never cools down the house
- Vents blowing air that is barely cooler than the room
- The outdoor unit humming or clicking but the fan not spinning
- Puddles near the air handler or water stains on the ceiling beneath it
- An iced-over evaporator coil or frozen refrigerant lines
- A hot electrical smell or a tripped breaker whenever the air conditioner kicks on
- Rising electric costs paired with a sticky, uncomfortable house
