Top CASI0 cold-climate picks, by size

Only units that keep at least 70% of their heat at 5°F, ranked on heat kept, efficiency at 5°F and seasonal efficiency (HSPF2), against units their size.

Showing Ductless, Up to 1.5 tons (under 21,000 Btu/h cooling), the most-listed ducted size. Pick yours above. What size is my system?

None of CASI0’s 3 models of this size and type qualifies: each keeps less than 70% of its heat at 5°F or is missing a rating. Its sizes: Ductless, up to 1.5 tons, Ductless, 2 tons, Ductless, 2.5–3 tons.

These are certified test ratings, not a recommendation for your home. The right size comes from a load calculation by a contractor.
