I bought this for my living room area because I have a dinosaur 4 ton heat pump that runs constantly. So far working great. WiFi program not so great.

This 12k unit keeps my 2 car garage extremely comfortable. The price was great.
Mini split AC's
I am just now getting these installed. @ almost done and the third one to go in the pool house. So far everything is good! Only wish I had bought them earlier when it was hotter here in Florida. Having a problem getting them to work with Alexa, but sure will figure it out!
Super quiet and efficient
Super quite barely using any electricity cooling my whole garage.
