Capacitor failure during summer heat
Why it happens here
Poway summers push heat pumps to run constantly from June through September. That continuous cycling wears out capacitors faster than in milder climates. When a capacitor fails, the fan or compressor will not start, and the system shuts down.
Our approach
We test capacitors with a capacitor tester on every summer call, even when the complaint is something else. We replace failed ones with matched parts and check the contactor and compressor for heat damage before we leave.
