Geothermal Tax Credits

Geothermal Tax Credits are available for newly installed systems. Since these are tax credits, rather than deductions, they save you full dollars, rather than just a percentage of a dollar. When comparing installation or replacement of regular air-to-air HVAC systems to geothermal, don’t forget to keep in mind that tax credits can make up a good portion of the upfront cost of the geothermal system.
