WHAT SHOULD I LOOK FOR FIRST WHEN PURCHASING A PORTABLE AIR CONDITIONER?
The right air conditioner helps you cool a room efciently. An undersized unit won’t cool adequately while one that’s too large will not
remove enough humidity, leaving the air feeling damp. To nd 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 to each other- 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 very sunny room, in a kitchen, or in a room with high ceilings. After you’ve found
the right cooling capacity or your room, you can look at other features.
WHY IS THE COOLING CAPACITY LOWER ON NEWER MODELS THAN ON OLDER UNITS?
Federal regulations require manufacturers to calculate cooling capacity based on a specic test procedure, which was changed just this
year. Models manufactured before 2017 were tested under a different procedure and cooling capacity is measured differently than in prior
years’ models. So, while the BTUs may be lower, the actual cooling capacity of the air conditioners has not changed.
WHAT IS SACC ?
SACC is the representative value of Seasonally Adjusted Cooling Capacity, in BTU/H, as determined in accordance with the Department of
Energy (DOE) test procedure at title 10 Code of Federal Regulations (CFR) 430, subpart B, appendix CC and applicable sampling plans.
