In October 2017, the Department of Energy implemented a new test procedure to determine the BTU rating of portable air conditioners. The procedural change has adjusted the amount of BTUs allowed to be claimed downward by as much as 50%. There have been no internal changes to these units, and the functionality remains the same. Please refer to room size guidelines to find the portable air conditioner that best meets your needs.
