Amazing Product Awesome Customer Service!

I live in southern California and run an Airbnb out of my home. I was always concerned that my guest couldn’t control there own heat or A/C. So I decided to research my options. In so doing came across the Mr Cool split. After looking at other options all of which were way more expensive, I settled on the Mr Cool Mini split and decided to install in my self. The step by step instructions were easy to understand and well illustrated. After completing the project and starting the unit I was amazed how quiet and efficient the unit was! I would not hesitate to recommend this product to my friend ends and family.

Efficient & Easy to Install

My husband and a friend installed this in 2 days. The friend is an experience contractor, but both said it went in fairly easy. We put it in our bedroom. It is quiet and very efficient. The unit was a little larger than I'd hoped, but it's doing the job, so I'm OK with it.
