Our score	SCORE6.4 / 10	SCORE7.5 / 10
Our take	The better Leto heater for a small room: 70% of its rating at 5°F, more than the 115V 12k makes. Senville still says the line heats only to 5°F.	Gree's premium tier in its smallest size: 11,500 BTU/h at 5°F and 30.0 SEER2. Contractor install only.

Watch out for	Amazon Leto listings don't state refrigerant; current R-454B pairings are SENL-xxCD-OL + SENL-xxCD-ILL, older R-410A ones end /OY + /IY. Senville's FAQ says no to owner installs, and the warranty requires a licensed HVAC contractor.	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.
