Perfect for a home without ductwork or a newly converted space, our PreferredTM Series multi-zone heat pump might be the right choice for you. As a part of the MGR Multi-Zone Ductless System, you can use up to five indoor units supported by just one outdoor unit. The Inverter compressor delivers year-round comfort on the hottest summer days to colder, winter nights (100% capacity as temperatures down to 5° F when properly sized and matched with specific indoor units).
