GREE VIREO ULTRA 36,000 BTU 23 SEER Mini Split System

Cold-Climate Heat Pump with Ultra-Heating to -31°F, 36000 BTU

Many heat pumps lose effectiveness as outdoor temperatures drop, forcing growers in cold climates to fall back on separate supplemental heat. The GREE VIREO ULTRA is built to keep working through that gap, with Ultra-Heating technology rated to continue heating down to -31°F while still delivering 36,000 BTU of cooling and 34,600 BTU of heating at 23 SEER efficiency.

This kit includes the wall mount indoor unit and outdoor compressor sized to heat and cool up to 1,600sq ft, suited to a larger room or growing space in a cold-winter climate; a line-set is sold separately and required for installation.
