I have a large room with a valted ceiling 23ft.X20ft. with southern exsposure that gets lots of sun on two sides of the room. We are having 90* to 100* days for several months I needed the largest AC window unit I could find that runs on 120V. This Friidaire 15,100-BTU was the largest I could find and it works great. I can set the timer to come on three to four hours before I get home and the room is very cool when I get home. Unit runs fairly quit and works great to cool the room down as cool as you want it or can stand it.
