This air conditioner arrived in a reasonable time frame but when I took it out of the box, read the directions and then hooked it up, it did not blow any cold air out at all. Furthermore, even if it did, the directions recommend that there be no bends in your exhaust tubing. This limits the amount of windows that you can install it in because the exhaust port is about 18 inches off the floor so you would have to have a low window to comply with that requirement. I put my on a table to raise it up enough to meet this requirement. This A/C unit does not seem very portable and it did not work right out of the box. Furthermore, there is an evaporator that pumps water into your air, This function is available to assist in making your unit more efficient. If you live in a humid environment already, such as the Great Lakes area, this seems like a bad idea. I want to reduce the humidity in my house not add to it. I sent this back and am going to buy a 15000 btu window unit. I don't recommend this unit to anyone.
I haven't used this product much yet, but so far I like it. It cools my large living room quickly and it's not amy noisier than a window AC. Set up was more compicated that I hoped for - I had trim the window kit to fit, and there were gaps around it, whch I wa able to seal with some weather stripping. But otherwise I"m happy and would say it's a good unit.
