Geothermal Finder is a free, independent directory of 2,375+ certified geothermal heat pump installers across all 50 US states. Every contractor listed is sourced directly from public state licensing records — no paid placements, no sponsored results, no pay-to-rank. Whether you need a ground source heat pump installed on a rural acreage or a suburban lot, the directory gives you an unfiltered view of licensed professionals in your area. Use the search above to find geothermal heat pump installation contractors near you, or use our federal geothermal tax credit calculator to find current state and utility incentives (the federal §25D credit ended December 31, 2025 under P.L. 119-21).

Each contractor profile shows the loop types they work with — horizontal, vertical, pond/lake, or open loop — alongside their licensing credentials and available customer ratings.
