Our scoreSCORE6.9 / 10SCORE7.5 / 10
Our takeOur default no-vacuum kit for a garage, shop or room on 115V, with a warranty that covers your own install and the line set. It makes 8,400 BTU/h at 5°F, less than cheaper flare units, and only 3,800 at -13°F.Makes about as much heat at 5°F as a Livo 18K and heats to -22°F. The pick within Gree if this is a room's main heat.

Watch out forOne Amazon listing with this model number is sold as a "Condenser"; confirm the wall unit is in the box before you pay. 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.
