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.
Best Answer: A 115 volt, 10,000 BTU Window Air Conditioning unit is capable of cooling a 500 square foot room without much strain on the unit. So a good rule of thumb is 20 BTUs per square foot. So for example, if your room to be cooled is approximately 10 x 25 you would have a 250 square foot space to cool, and would require a 5,000 BTU unit to handle the job. Caution when choosing a unit not to way overdo the BTU requirement. Many will buy a much larger unit thinking they are doing themselves a favor.
