Capacity as it gets colder

Solid dots: 5°F and 47°F medians, joined by the straight line our model uses. Open dot: the 17°F median as reported, which is a separate test condition and often falls below the 5°F maximum-capacity figure.

Across the 201 systems, 5°F capacity runs from 6,300 to 54,000 BTU/h, so the model matters more than the badge. Refrigerants used: R-32, R-410A, R-454B.
