When financing your new geothermal system, you can choose one or both* of these loan types:

  • A 12– or 18–month loan that covers your geothermal tax credit (i.e. the Section 25D federal income tax credit that’s available for new residential geothermal systems at up to 26% of the eligible project cost in 2020 and up to 22% in 2021).
  • A 12–, 15–, or 20–year, fixed rate loan on the remaining portion of your geothermal system cost (i.e. up to 74% of the eligible project cost in 2020 and up to 78% in 2021).

*Combining both of these loan types together is commonly called a geothermal system “combo loan.” Learn How Combo Loans Work


By offering up to 100% financing with no money down, our geothermal system loans allow you to swap your monthly electric bill for a monthly loan payment on a geothermal system—one which you would later own free-and-clear at the end of the loan repayment period.

Loan Benefits:

  • Secured by the geothermal equipment that's installed, not by the equity in your home
  • Loan amounts up to $90,000 per loan
  • Fixed interest rates
  • No prepayment penalties
  • Automatic electronic payments

Debt Protection Program:

What's more, you can opt in to be protected under the Clean Energy Credit Union Debt Protection program. In the event of an unexpected financial hardship event, your loan balance or monthly loan payments may be cancelled without penalty or added interest. This program provides the peace of mind that comes with knowing you and your credit rating are protected—and most importantly—that your family is protected.

Frequently Asked Questions (FAQs):

Do I have to work with one of the Credit Union’s partners for my clean energy project?

No. When you apply for a clean energy loan with Clean Energy Credit Union, you can work with any contractor, vendor, or service-provider that you choose. However, the Credit Union offers special loan offerings via its partners because they, in return, provide multiple value-added services to the Credit Union that reduce our costs and overhead. Learn more about our partners.

How can I find out if there are incentives available in my area for clean energy products and services?

We recommend checking the Database for State Incentives for Renewables & Efficiency (DSIRE): We also recommend asking your clean energy contractor, vendor, or service provider as they can typically help you explore what incentives may be available in your area.
