How is a window air conditioner cooling capacity measured?
Window unit A/C cooling capacity is measured in BTUs (British Thermal Units). Higher BTUs mean a greater cooling capacity. The U.S. Department of Energy’s EnergyStar division issues BTU recommendations (per hour) based on room square footage space. These recommendations translate to the window unit A/C BTU category that you should buy.
What’s the difference between a small and large window air conditioner?
In other words, small window air conditioners often have smaller BTU ratings, while larger BTU capacity often translates to a larger unit. This may become a problem when the right size of window air conditioner—when measured by BTUs—won’t fit inside the window opening.
