Geothermal heat pump costs range widely depending not only on the size of the pump, but how easy it is to install in your ground. These heat pumps are generally rated by the ton, with a ton equaling around 12,000 BTUs of heating potential. A one-ton model can cost between $2,500 and $8,000, while a large five-ton model can cost up to $40,000.
Yes, professional installations include trenching or borehole drilling required for ground loops.
