Shop 5 Ton Heat Pump Complete Split Systems, designed for large homes, offices, and light commercial spaces between approximately 2,400 and 3,000 square feet. A heat pump works by reversing the flow of refrigerant, heating the indoor coil so that cold air passing over it becomes warm air for your home. In summer, the system switches to cooling mode, removing heat from inside just like a traditional air conditioner. Each system also features a backup electric heat strip for colder days. Family owned and operated for over 30 years, we offer fast shipping, free duct designs with every system purchase, honest pricing without hidden fees, and experienced warranty and customer support.
