If you happen to live in a home without ductwork or have a converted area for a living/working space, you'll appreciate this multi-zone heat pump. The MGR System can provide year-round comfort, cooling for those hot summer days and warmth the rest of the year, even when temperature dips down to 5° F at full heating capacity (with the right size and system combination). As a multi-zone, you can use up to five multiple style indoor units supported by just this one efficient, outdoor Inverter compressor unit. For quiet comfort in a multi-space application, it can't be beat.
