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.
A standard unit of measurement used to denote both the amount of heat energy in fuels and the ability of appliances and air conditioning systems to produce heating or cooling. A BTU is the amount of heat required to increase the temperature of a pint of water (which weighs exactly 16 ounces) by one degree Fahrenheit. Since BTUs are measurements of energy consumption, they can be converted directly to kilowatt-hours (3412 BTUs = 1 kWh) or joules (1 BTU = 1,055.06 joules). A wooden kitchen match produce approximately 1 BTU, and air conditioners for household use typically produce between 5,000 and 15,000 BTU.
