Our scoreSCORE6.9 / 10SCORE7.5 / 10
Our takeThe most efficient size in the line and a fair bedroom heater on 115V, but at -13°F it is down to a 3,800 BTU/h maximum, so cold nights need backup heat.Gree's premium tier in its smallest size: 11,500 BTU/h at 5°F and 30.0 SEER2. Contractor install only.

Watch out forMRCOOL 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.
