Our takeHeats to -13°F, but at 5°F it makes less than the Della Serena or Pioneer Diamante Pro 18K, which also give a self-installer warranty coverage Gree won't.Full rated output at 5°F, matching the Olympus E Star 18k value for value, and it cost less than the Amazon Olympus when we checked. Licensed install required.

Watch out forGree's submittal prints a higher 47°F rating (19,100 on the 18K, 24,000 on the 24K) than the certified figure. The LIVO+ (LIVS..., R-410A, 16 SEER) and Livo Gen 3 / Gen 4 (4LIV, R-410A) are different units; confirm both model numbers end R32AO and R32AH. The 18K Amazon listing titled "Gree R32 LIVO+" reports the R-410A LIVS18HP230V1B; we don't link it. Gree's warranty applies only to installs by a state certified or licensed HVAC contractor, and claims are contractor-only.The Amazon 18k listing gives 2 yr parts / 7 yr compressor; confirm the term for the model you receive. The Amazon Aura listings don't state refrigerant. The 12k listing (SENA-12HF-16) shows a 25.5 efficiency figure that matches the older R-410A Aura and a 2 yr parts / 7 yr compressor warranty field; confirm model and refrigerant before you pay. Current R-454B wall pairings are SENA-xxHF-OG + SENA-xxHF-IGG; older R-410A pairings end /OQ + /IQ. Senville's site lists higher HSPF2 and 47°F heat than the AHRI figures on NEEP; we use the certified numbers. Senville's FAQ says no to owner installs, and the warranty requires a licensed HVAC contractor.
