18000 btu or 1.5 tons.
I am looking for a window AC unit to use in my whole house. What is the BTU's one would need to cool a whole house?
8000 BTU =2344.66 watts 1 watt = 3.412
The smallest air conditioner you can find would be appropriate.You'll probably have to cut it on and off too.
48000 btu
Between (.07) and (.24) BTU per cubic foot. For Central Air, might be better to use (.07 BTU per Cu.Ft.) For window AC unit cooling 150 square feet, use (.024 BTU per Cu.Ft.) For window AC unit cooling 1600 square feet, use (.07 BTU per Cu.Ft.) [[[ All scenarios assume 8 foot ceilings ]]]
1500 square feet
I am not an expert, but I have cooled a 12 x 18 room, 206 sq. ft. with a 9,000 BTU window unit, and it gets hot in Texas. Take it from there.
24,000 btu
37000 btu
It could be due to cold temperatures, yes.
Window AC units CANNOT be recharged at any reasonable expense. They normally hold about 8-14 onces.
