I installed my new 4 ton A/C unit along with this Hard start. I honestly feel that a good Hard Start like the csru3 will help make my compressor last long. It takes as much as half the stress off of the compressor with each start. To me it is a MUST have for any A/C unit.

I wish I had read about these sooner, after much research this brand was the most reccommended by the ac tradesmen. I am sure i caused a much shorter life of my compressor due to slow starts, but i feel my comp. Will live years longer now with the 5-2-1 installed.

My compressor will not start. This compressor saver was easy to install and only tool a few minutes. Now my compressor start and cold air is here to stay. Note, the hardest part was to locate the Common to the compressor.

Before installing, the lights inside my home would dim considerably whenever the AC condenser would kick on. We recently purchased the house which was built in 2001 and has the original condenser outside. I replaced the capacitor only and that seemed to help with the lights dimming but did not stop it entirely. After adding the 5-2-1 hard start kit, the light dimming problem is entirely gone on most lights and very sensitive ones hardly dim at all. Here’s to hoping I get some more years out of the condenser before it has to be replaced entirely.
