Most AC breakdowns in Centreville 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
Spotting the early warning signs lets you act before the problem gets expensive. These are the signals our technicians see most often:
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- A hot electrical smell or a tripped breaker whenever the air conditioner kicks on
- An AC that turns on and off every few minutes but never cools down the house
- Water dripping from the indoor unit or showing up on the ceiling below
- Rising electric costs paired with a sticky, uncomfortable house
- An iced-over evaporator coil or frozen refrigerant lines
- Room-temperature air from the registers even though the AC is running
- A condenser fan that sits still while the outdoor unit hums
