Spec Della Serena 24,000 BTU 230V Gree Sapphire R32 24,000 BTU 230V Photo Our score SCORE 7.3 / 10 SCORE 7.5 / 10 Our take Keeps 87% of its rating at 5°F, the best retention in the Serena line, for a bigger shop where winters stay above 5°F. Out-heats the bigger Livo 30K at 5°F and still lists 17,000 BTU/h at -22°F. Buy it when this is the main heat in a cold climate and a licensed contractor is installing it.

Della's printed manual says the extended warranty is for professional installation; the current web policy gives registered DIY installs replacement parts at Della's discretion. Screenshot it the day you buy. Della also sells Vario, Optima Pro, Hyper Heat and older R410A lines; most owner reports are about those. 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.
