The right air conditioner helps you cool a room efficiently. An undersized unit won't cool adequately,
while one that's too large will not remove enough humidity, leaving the air feeling damp. To find
the proper air conditioner, determine the square footage of the room you want to cool by
multiplying the room length by its width. You also need to know the air conditioner's BTU (British
Thermal Unit) rating, which indicates the amount of heat it can remove from a room. A higher
number means more cooling power for a larger room. Be sure you are comparing only newer
models as older models may appear to have a higher capacity, but are actually the
same. Be sure to "size up" if your portable air conditioner will be placed in a sunny room, in a
kitchen or in a room with high ceilings. After you've found the right cooling capacity for your
room, you can look at other features.
Federal regulations require manufacturers to calculate cooling capacity based on a specific test
procedure, which was changed this year. Models manufactured before 2017 were tested under
a different procedure and cooling capacity is measured differently for modern models than those
in prior years. So, while the BTUs may be lower, the actual cooling capacity of the air
conditioners has not changed.
SACC is the representative value of Seasonally Adjusted Cooling Capacity, in BTU/h, as determined
in accordance with the DOE test procedure at title 10 Code of Federal Regulations (CFR) 430,
subpart B, appendix CC and applicable sampling plans.
