How we countedThe count uses each product's current fit ratings for “For long runtimes I need a tougher unit”, “It is going to live in a crawl space”, and “The space remains very wet or smells musty”. A need with no documented match is not counted.
How we calculatedOnly figures stated as ENERGY STAR, Appendix X1 or official current-condition results count. When a current test figure exists, older hot-saturated labels are left out. The median draws on the 9 of 31 models that publish comparable figures.
