I'm not thrilled. The room is 244 SF, and this unit does not cool it well at all. The compresser constantly turns on and off, even when it is in normal mode, and not energy save mode. I'm not sure why it would do this. It seems it should only be doing that in energy save, it does it all the time. A 6,000BTU should do the job for this size room. I have a 5,00 BTU in another room the same size, and it is great.(mechanical)
