Really good system! Took one day to install with excellent directions. Ran the system to test it and it worked as advertised. Used it to cool down a restaurant dining area and it did job with happy customers. Thanks Mr. Cool!

Split A/C & Heating Unit
I have to say " YES" I would buy this product again. It has made my basement into a real living space. I had a competent electrician put it in, DIY IT IS NOT. I wanted Heat , but NOT the heat of a burning house.

New Review
Posted didn't work well for heating under 40 degrees, but that was on Auto setting. I discovered Heat setting does work better for heat. 10 degrees out still blowing warm. My son and I installed almost 2 years ago. Air Conditioning is fantastic too.
Additional Review
They are less expensive and Gen 5 now. We have had and used Gen 4 my son and I installed in May, 2024. My original review said needed additional heat source when below 40 degrees, but I discovered the heat works best when heat setting is used instead of Auto. 10 degrees f outside now and still warm
