ENERGY STAR cold-climate list
LG cold-climate mini-splits
The short answer
LG has 210 ENERGY STAR cold-climate certified system combinations. The median one is rated 26,200 BTU/h at 5°F, which is 97% of its 47°F capacity (the all-brand median is 88%), with a median HSPF2 of 9.8. Among the 80 brands with 50+ systems, it ranks #4 for keeping capacity in the cold.
Capacity as it gets colder
Across the 210 systems, 5°F capacity runs from 7,700 to 54,000 BTU/h, so the model matters more than the badge. Refrigerants used: R-32, R-410A.
