A Greenwood homeowner called because the AC was not working and made a loud, high pitched noise every time it tried to turn on.
What Our Technician Found
Our technician tested the capacitor with a meter and it read bad. The capacitor is a part that stores a burst of power and gives the motors the push they need to start. When it fails, the motor tries to start without that push and can hum or squeal instead of running.
What We Completed
- Tested the outdoor unit’s electrical parts.
- Tested the capacitor with a meter.
- Replaced the capacitor.
- Checked the system after the repair.
The Result
The outdoor unit has a new capacitor and starts the way it should. Learn more about our AC repair.
What Homeowners Can Learn From This Job
- A loud hum or squeal at startup is a warning. The motor may be struggling to start.
- Turn it off if it keeps trying. Letting it strain can damage the motor.
- Capacitors are a common fix. Testing tells you for sure.
