Watch out for	Senville's FAQ says no to owner installs; warranty registration asks for the installing company and invoice. Senville's site lists higher HSPF2 than the AHRI figures on NEEP; we use the certified numbers. The Amazon 18K listing model field reads SENE-12EL-16 while the part number is SENE-18EL-16.	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.
