I bought this for my shop. It’s a 20ftx40ft shop. I have my dogs inside of it and it’s not an insulated building. This unit does the job plus some. These dogs are always cool and I can’t complain myself when I’m out there working on projects. I’d recommend this unit to anyone. Especially since I was in the A/C - Refrigeration trade for over 20years. The features are great. I can pre cool the room with the app from wherever I am! This is a great unit!
