Products are listed as the EPA publishes them on the date this page was read, and the EPA can revise or withdraw a certification. A product is counted once, under the most specific list that holds it. For heat pumps each ENERGY STAR ID is one outdoor and indoor unit combination, so a model number can repeat. Brand names are as published. This page uses EPA data and is not endorsed or certified by the EPA or ENERGY STAR. Free to reuse with credit to SpecStream under CC BY 4.0. Spot a wrong value?
