Geothermal calculator

What would geothermal cost you?

Compare geothermal with a conventional HVAC system over 50 years, see what the federal credit is worth to you, and what it could build.

How to use it

Pick who owns the building. Schools, churches, nonprofits and local governments get the federal credit as a cash payment. Businesses get a tax credit.
Enter the conventional HVAC price. Use a bid or quote for rooftop units, boilers or chillers. A rough number works.
Compare and decide. See both systems over 50 years, then keep the credit or put it toward a project, like a new parking lot built over the well field.
