ENERGY STAR cold-climate list
Carrier cold-climate mini-splits
The short answer
Carrier has 200 ENERGY STAR cold-climate certified system combinations. The median one is rated 18,000 BTU/h at 5°F, which is 90% of its 47°F capacity (the all-brand median is 88%), with a median HSPF2 of 10.5. Among the 80 brands with 50+ systems, it ranks #32 for keeping capacity in the cold.
Capacity as it gets colder
Across the 200 systems, 5°F capacity runs from 7,000 to 54,000 BTU/h, so the model matters more than the badge. Refrigerants used: R-410A, R-454B.
