Had it installed in my 3 car garage and it maintains 83 degrees easily. I had a certified electrician do the wiring and a HVAC contractor do the hardware install. First mini-split AC I ever had, and can not speak to the increase in my electrical; bill...

I've had this unit up and running for about three months now. I like being able to isolate the rooms I want to heat/cool. The unit is very quiet.
