Mine were Mitsubishi and I put in 6 of them. A lot of work as 3 of them were in upstairs bedrooms, 2 in the living room area, and 1 in an in law apartment on the basement level. In my current house I have a 4 season porch that has a Sanyo strictly for ac but in truth other than the hottest periods the central ac of the rest of the house allows enough cooling in this room if we leave the door open but we close it off when we leave the house so it can be toasty in there...
