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.
5. BTUs/Room Size â A portable air conditionerâs BTUs tell you how powerful the unit is. This directly affects the room size and how quickly the unit will be able to cool. The higher the BTU, the larger the area the portable air conditioner can cool.. The short answer is yes. Much like any air conditioning system, all portable air conditioners need to be vented in some form or fashion. Portable air conditioners pull in warm air, cool it, and expel the cooled air out of the front of the unit and the remaining warm air and moisture out of the back of the unit.
