Common Questions

Are these tools really free?

Yes, completely free — no account, no email required. We built these tools to help homeowners and contractors make informed decisions about geothermal energy.

Do these tools produce a project quote or design?

No. They organize the evidence needed to compare proposals. Final price and design require calculated loads, exact equipment, site and ground work, local approvals, and complete written bids.

Is the federal residential geothermal credit still available?

No. The former Section 25D residential credit is unavailable for property placed in service after December 31, 2025. Other programs have separate rules and must be verified directly.

Can I use these tools for commercial projects?

Use them only as a document checklist. Commercial design, incentives, tax treatment, ownership structures, and approvals require project-specific qualified advice.

Do I need permits for a geothermal installation?

Requirements depend on the exact location and design. Confirm building trades, well or bore, water, environmental, utility, property, and local approvals with every responsible authority before work.
