Sizes certified to cover a typical house at 45°F
The size calculator uses 16 to 26 Btu/h per square foot for a typical house where the design temperature is 20°F or warmer. Sizes are compared on the 5°F full-speed test.
For each type: the smallest size class whose median model is certified to deliver the bottom of the range at 5°F, and the smallest that reaches the top. The medians count one value per model. Size classes are named by cooling capacity.
