Frequently Asked Questions

How do I find a geothermal installer near me?

Enter your city, state, or ZIP in the search box at the top of this page, or pick your state from the grid below. You'll see geothermal contractors in your area with their contact details, so you can reach out directly — no account or referral fee required.

How do you check the contractors listed here?

Listings are compiled from state licensing databases and public business records. Where a company provides a licence number or an IGSHPA certification we show it on the listing, and we flag accredited installers so you can prioritise them. We do not independently audit every listing, so confirm credentials with the issuing authority before you hire.

Does it cost anything to use the directory?

No. Searching Geothermal Finder is completely free for homeowners and businesses. We don't charge referral fees or sell leads — when you request a quote, your details go directly to the contractor you chose.

What is IGSHPA certification?

IGSHPA (the International Ground Source Heat Pump Association) certifies installers who complete accredited training in designing and installing geothermal heat pump loop systems. Choosing an IGSHPA-certified contractor helps ensure your system is sized and installed to industry standards.

Do you cover Canada?
