My son had these from several businesses. The big one is a edgestar 14000 btu. he used it to cool a shop. It was cooling 700 sq ft. It has the window kit. Work fine. The other 2 are black and decker 10000 btu. They were never used but one has a PF code and the other doesn't blow super cool. 30.00 dollars buys all 3. He just asked me to get rid of them.
