Review on Kismile Portable Air Conditioners 14,000 BTU,Cooling, Dehumidifier & Fan 3-In-1,Air Conditioner Portable With Remote Control, Quiet AC Unit Cools Rooms Up To 700 Sq. Ft For Room/Office/Bedroom by Erica Wilson

So easy to set up. We vented this through our block house to save the ugliness of venting through the only window facing the front of the house. The room is about 300sf and gets super hot to the point we couldn't stand spending any time there. I needed to place my office with computer, printer, etc. sensitive to the heat. This has solved our problem. It's quiet and cools the room to a comfortable temperature within 30minutes and holds the temperature after shutting down for several hours (we checked this in early evening hours).
