    Compressor saver

    These start assist should be on every AC unit that they can be used on....They save electric cost, help keep the compressor from struggling against high starting torques and are a great selling item when they are explained to customers.... They install easily and I recommend them to anyone and everyone running service or just wanting to make an AC unit more efficient... These start kits can add years of service to a unit....Especially if coupled with a time delay to prevent short cycling...A perfect combination.... Bottom line......I will buy and install more. Vern

    Quick fix for abused compressor

    My old 15000 BTU wall unit began tripping the time delay on the circuit breaker when starting. This fixed it. Installation was just a matter of attaching the leads to the H and C terminals of the existing run capacitor and finding a way to secure it.

    Great booster.

    This booster works! My geothermal scroll compessor was making a clunk sound during startup with a loud buzzing noise. This booster, plus a new start/run capasitor fixed the clunk noise and has quieted the buzzing. I recommend it. FYI: Where I live, it would cost $60 for the part plus $90 labor for this item to be installed. You can easily install it yourself. All you need to do is watch a short video on YouTube in order to get aquatinted with handling a capasitor.

    IT SEEMS TO BE WORKING?

    This item is supposed to take some of the "electrical stress" off of your compressor by giving itban extra "boost" on Start up. It may be my imagination, but I swear the compressor does not have the same loud tone upon starting like it did before. If you can use common tools, installation is a snap. Look at the YouTube video on installation, get some plastic ties and that's it. 🙂

    Boosts compressor starts

    Easy 2 wire connection to current run capacitor. Doesn't matter which goes on each side. Each side usually has 4 spade connectors to use, just use one of them for each wire for each set. Also has relay that let's it kick in when other cap is triggered.
