This is the BEST window A/C unit that we have ever owned! It not only cools one room, but also a small open room next to my living room. I have hot flashes and live in the south, so this is a must!! Works very well and it's also very quite. My husband had zero problems installing this unit. Cools space in no time. Bonus: It is WiFi compatable. I could not be any more happier than I am with this A/C. Happy wife = happy life haha!! And HAPPY I am!!!!!!!! Oh one more thing, from a Brand that my family loves and trust!
