Great Product to Extend Compressor LIfe

Your review: I installed two of these 3W2 hard start systems on HVAC compressors. I expect doing this will extend the life of the entire system for some time once the factory star/run capacitor has weakened. Like the install bracket too helped the install.

Pros: Easy of install Bracket

Cons: None
