If you prefer higher heating temperatures from your registers in winter or just want to continue using an existing furnace, this indoor unit may be what you need.

The INFINITY® GZ geothermal split system heat pump combines superior performance with the smart, powerful and intuitive Infinity Touch control.

This system utilizes your new or existing furnace or fan coil’s blower motor to move air and offers the efficiency and comfort benefits of a two-stage compressor, all tied together with the versatile programming, energy tracking and available wireless/remote operation of Infinity Touch.

Perhaps best of all is a Federal tax credit still available on qualified geothermal heating and cooling systems. So, you can revel in getting a tax credit of 30% of your installed cost of a geothermal system1.
