How much does it cost to install geothermal systems?

A geothermal system in a home with 2,500 square feet and a heating and cooling load of 60,000 BTU costs between $20,000 to $25,000 to install. This is almost double the price of traditional systems.

There are federal and state rebates for the installation of geothermal systems that can lower the price of installing a geothermal system. While the price of geothermal systems is significantly more than traditional systems, the geothermal systems can reduce utility costs by 40 percent. Depending on the specific cost, the payback of the geothermal system can range anywhere from two to 10 years, though the system lasts well beyond that.
