I just put a Cruise Aire in mine. So far, so good. My only problem is it's too big. When I started talking to my AC guy about doing the job, we were looking at the brochure at the different models. He suggested the 16K BTU, but I thought it might be too big and decided to go with the 14k unit. When he went to order it, the 14K had been discontinued so he got the 16k and I wish I had gotten the 14k.
