Shop 3 Ton Heat Pump Complete Split Systems, perfect for efficiently heating and cooling larger homes, offices, or zones between approximately 1,400 and 1,800 square feet. A heat pump works by reversing the refrigerant flow, heating the indoor coil so that cold air passing over it becomes warm air inside your home. In summer, the system switches back to cool by removing heat from indoors like a traditional AC. These ducted systems include a backup electric heat strip for colder weather. As a family owned and operated business for over 30 years, we offer fast shipping, free duct designs with system purchases, transparent pricing, and expert warranty and customer support.
