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.
Most air conditioners have their capacity rated in British thermal units (Btu). A Btu is the amount of heat necessary to raise the temperature of 1 pound (0.45 kilograms) of water one degree Fahrenheit (0.56 degrees Celsius).One Btu equals 1,055 joules. In heating and cooling terms, one ton equals 12,000 Btu. A typical window air conditioner might be rated at 10,000 Btu.For comparison, a typical 2,000-square-foot (185.8 square meters) house might have a 5-ton (60,000-Btu) air conditioning system, implying that you might need perhaps 30 Btu per square foot.s an example, if a 10,000-Btu air conditioner consumes 1,200 watts, its EER is 8.3 (10,000 Btu/1,200 watts). Obviously, you would like the EER to be as high as possible, but normally a higher EER is accompanied by a higher price.
