Shop 2.5 Ton (2 1/2 Ton) Heat Pump Complete Split Systems, built to efficiently heat and cool spaces between approximately 1,200 and 1,500 square feet. A heat pump works by reversing the flow of refrigerant, making the indoor coil hot so cold air passing over it becomes warm air for your home. In cooling mode, the system removes heat from inside, just like a traditional AC. These ducted systems also include a backup electric heat strip for colder days. Family owned and operated for over 30 years, we offer fast shipping, free duct designs with system purchases, honest pricing with no hidden fees, and top-notch warranty and tech support.
