Researchers at the National Renewable Energy Laboratory (NREL) studied window air conditioners on behalf of the U.S. Department of Energy’s Building America program, to understand how they perform and how they could be improved. NREL engineers found that window air conditioner installation resulted in significantly more air leakage. In this video NREL’s team shows a few simple steps to improve both efficiency and comfort of the units.
