Want To Add 5 Years To The Life Of Your Compressor?

Does your compressor make a hellacious noise upon start-up?

Do your lights dim every time your unit turns on ?

Adding a Hard Start Assist to your system can erase those problems and add at least 3-5 years to the lifespan of your compressor. That’s not even the best part, the best part is you can install it yourself for under $50.

What is a Hard Start Assist?

A Hard Start Assist stores energy inside it’s capacitor and when the unit turns on it uses that energy to aid the compressor upon start-up. After start-up the Hard Start Assist then uses the power from the unit to recharge itself so it’s ready to help again on the next heating or cooling cycle.
