How we countedThe count uses each product's current fit ratings for “I would like supplemental heat too”, “I want less hot outside air getting in”, and “Either the room is large or its heat load is heavy”. A need with no documented match is not counted.
How we calculatedOnly SACC or DOE/SACC figures count. Headline ASHRAE numbers are left out. The median draws on the 22 of 23 models that publish comparable figures.
