Failed run capacitors on older systems
Why it happens here
Greenville summers run the compressor at high load for months, and the run capacitor weakens with every heat cycle. In homes built before 2000, the original capacitor is often well past its service life by the time it fails.
Our approach
We test capacitance with a multimeter and replace the capacitor with a matched part. We also check the start capacitor and contactor at the same time, since they tend to fail together after years of heat exposure.
