The required BTU (British Thermal Units) for a window air conditioner depends on the size of the room you want to cool. As a general guideline, you'll need about 20 BTU per square foot of living space. For example, a 150-square-foot room would require approximately 3,000 BTU, while a 500-square-foot room might need around 10,000 BTU. Other factors, such as ceiling height, sunlight exposure, and the number of occupants, can also influence the BTU requirement.
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?
The smallest air conditioner you can find would be appropriate.You'll probably have to cut it on and off too.
48000 btu
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.
It could be due to cold temperatures, yes.
37000 btu
24,000 btu
Window AC units CANNOT be recharged at any reasonable expense. They normally hold about 8-14 onces.
You need between 20 and 22 btu per square foot in an average home. So, 121 x 20 = 2420 or ~2500. 121 x 22 = 2662 or ~2700. So 2500 to 2700 btu.
A 6500 BTU window air conditioner typically uses around 5-7 amps when running. However, the exact amperage can vary depending on the model and specific operating conditions. It's always best to check the manufacturer's specifications for precise information.
