Most AC breakdowns in Garland trace back to 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 freeze solid once a dirty filter chokes the airflow.
When the heat goes out, see Furnace Repair.
Warning Signs for AC Repair
Spotting the early warning signs lets you act before the problem gets expensive. Keep an eye out for the following clues:
- Breaker trips or a burning odor at startup
- Clicking or humming outside with no fan movement
- Hissing or bubbling sounds that suggest a refrigerant leak
- An AC that turns on and off every few minutes but never cools down the house
- Water leaking around the indoor unit or from the ceiling below it
- Warm or room-temperature air blowing when the thermostat calls for cooling
- Cooling bills climbing while the house stays sticky and warm
- Frost or ice forming on the copper lines or the indoor coil
Don't Wait for a Total Failure
Left unchecked, even a small fault or temperature swing often signals a system working its way toward a breakdown. Call (972) 920-8553 at the first sign of trouble.
