Our takeThe small 5th Gen condenser, up to three heads with the new 6K units: 13,300 Btu/h at 5°F total. For two rooms, two single-zone units give more heat.18,000 BTU/h at 5°F against the Livo 18K's 12,100, for a cold-climate room with a licensed contractor.

Watch out forThe 4th Gen multi-zone (C suffix, R-410A) is a different system; its 18K ran two zones, not three. On earlier generations owners report idle heads still heating or cooling and rooms overshooting setpoint; there is no long 5th Gen record yet. Line sets are one-time installs; runs past the standard 24.6 ft per head and ducted (AHU) air handlers call for added refrigerant per the manual. Sold on Amazon by a third-party seller in small quantities; condenser only, heads and line sets sold separately.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.
