Most AC breakdowns in Dearborn Heights 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.

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:
- Rapid on-off cycling that never brings the temperature down
- Warm or room-temperature air blowing when the thermostat calls for cooling
- An iced-over evaporator coil or frozen refrigerant lines
- Higher summer bills even though the house still feels warm and humid
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- Clicking or humming outside with no fan movement
- Breaker trips or a burning odor at startup
- Water dripping from the indoor unit or showing up on the ceiling below
Early Action Saves Money
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Don't wait, call (313) 251-4079 and we'll take a look right away.
