Ranked by summer-long cooling efficiency only

Cooling efficiency over a whole summer, measured with a federal test. Like miles per gallon for cooling: higher means more cooling per unit of electricity over the test season. The federal minimum for a new split heat pump is 14.3. This list ranks by that one rating. For the units that hold up best in the cold overall, see the cold-climate picks.
