The capacitor is a small part, but it does a big job. It helps your AC motors start and keep running. When it fails, your AC may stop cooling.
Signs of a bad capacitor
You may hear a humming sound but the AC does not start. Or the AC turns off on its own. A bad capacitor is a common cause of these problems.
Why the heat matters
Capacitors can wear out faster in extreme heat, and Scottsdale has plenty of that. That is one reason this part fails so often here.
A quick fix for a pro
Replacing a capacitor is a job for a trained tech, since it deals with electricity. It is often a fast, low-cost fix. Call PolarFix if you think yours has failed.
