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. No featured offer on this Amazon listing when we checked; look under All Buying Options or buy from a MRCOOL dealer.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.
