Our takePlenty of heat at 5°F for a bigger garage, but at -13°F it makes less than the 18k, so it is the wrong upsize if your coldest nights are the problem.Out-heats the bigger Livo 30K at 5°F and still lists 17,000 BTU/h at -22°F. Buy it when this is the main heat in a cold climate and a licensed contractor is installing it.

Watch out forMRCOOL's catalog ticks ENERGY STAR Cold Climate for this size; NEEP's record says ENERGY STAR yes, Cold Climate no. Check the rebate program's own list. MRCOOL also called its older R-410A 4th Gen DIY "E Star"; confirm R-454B and a model number of the form DIY-...D25-O. DIYS- is the cheaper DIY Select and EZPRO- is the Easy Pro; a listing that says "5th Gen" and "Select" is the Select. The manual says the line sets install once; reconnecting them, or the pipes at the outdoor unit, voids the warranty.Amazon Sapphire titles show old SEER figures ("21.5 SEER" on the 24K); confirm the SAPxxHP230V1R32AH/AO model numbers. Gree's submittal prints lower 17°F figures than the certified NEEP ratings; go by NEEP. Gree's warranty applies only to installs by a state certified or licensed HVAC contractor, and claims are contractor-only.
