OUTSTANDING WINDOW AC ! Easy to install and energy efficient .. It can cool down large room in short time on the hottest day. After installing it looks very nice in the window. I like the way it operates . you can direct the stream of air in different directions for best flow. I love the quiet operation of the compressor and fan. I'm getting a fantastic night sleep now. An extra bonus is the remote control ! I can adjust the setting with out having to get up. I'm so pleased with this purchase.
