Our takeFor a big open zone with a licensed contractor lined up: 23,000 BTU/h at 5°F, 77% of its rating. A DIY install leaves it with no Gree warranty.32,600 Btu/h at 5°F and heat to -22°F, with a DIY-friendly 10/10/10 warranty when the Quick Connect line set is used. Efficiency dips to 16.8 SEER2.

Watch out forThe 30K listing's bullets copy old LIVO+ text ("16-SEER"); go by the model LIV30HP230V1R32AH/AO. 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.Install type 'quick-connect' assumes MRCOOL's optional No-Vac line set; the system also ships for flare or braze connections with a vacuum. Some Amazon listings carry older CENTRAL-xx-HP-230A00 model codes; match the 230B00-O suffix. The install manual still calls for a licensed installer and licensed field piping; the warranty is what exempts a Quick Connect install.
