Oklahoma Geothermal Rebates 2026 | Electric Cooperative Programs
Last updated: April 2026
The CKenergy Electric Cooperative geothermal rebate pays $2,000 per ton, up to $24,000, for qualifying installations in western and south-central Oklahoma. I’m Dave Hartzell, IGSHPA-Accredited geothermal installer serving CKenergy territory, including Blaine and Canadian counties, from my base in Kingfisher for 15+ years. I handle all rebate documentation. 4.8 stars / 276 reviews. Call 405-375-4822 for a free estimate.
Oklahoma’s electric cooperatives offer some of the most generous geothermal heat pump rebates in the country. Section 25C (air-source) expired December 31, 2025. The Section 25D geothermal credit also expired 12/31/2025, Oklahoma utility rebates remain fully active and are the primary savings vehicle for 2026. In some cases, co-op rebates have increased for 2026. I’m IGSHPA-Accredited and work directly with these co-op programs. Background reading: geothermal heat pumps.

Why a Local Installer Makes the Difference
I reach CKenergy territory from my base in Kingfisher, a straight shot west and south into Blaine, Canadian, and surrounding CKenergy counties. I’m not a metro OKC contractor unfamiliar with the area.
CKenergy customers in the 10-county service area can get up to $24,000 back. See the CKenergy geothermal rebate, up to $24,000 details and county map. Note: Kingfisher County is not in CKenergy territory.
I’ve installed geothermal systems for CKenergy members throughout my 15+ years in business. I know the program, I know the paperwork, and I’m accountable to the same community I serve.
- Local accountability, your neighbor, not a metro contractor
- IGSHPA Accredited, the certification CKenergy’s program requires
- ClimateMaster GeoElite Dealer, equipment that meets co-op efficiency requirements
- 15+ years installing geothermal in CKenergy territory, more local geothermal installs than any other contractor
- Full rebate paperwork included, AHRI cert, EER docs, contractor license, IGSHPA cert, completion report

CKenergy Member Financing, Stack a Low-Interest Loan on Top of Your Rebate
Most CKenergy members don’t know this: in addition to the $2,000/ton rebate, CKenergy offers low-interest energy efficiency loans to members, 6% interest, 4, 7 year terms. You can use the loan to cover your installation cost, then let the rebate pay a large chunk of it back.
Example: 4-Ton System in CKenergy Territory
| Typical installed cost (4-ton geothermal) | ~$24,000 |
| CKenergy rebate (4 tons × $2,000) | − $8,000 |
| Amount to finance through CKenergy loan | ~$16,000 |
| Monthly payment at 6% / 5 years | ~$309/mo |
*Example only. Actual costs vary by system size, ground conditions, and home. Call Hartzell’s for a free site estimate with exact rebate and loan figures.
To apply for a CKenergy energy efficiency loan: contact CKenergy directly at 405-656-2322 or visit ckenergy.coop. I can provide the system quote and documentation CKenergy needs to process the loan.

Federal Credits Expired, But Utility Rebates Are Real Money
Both the 25C (air-source) and 25D (geothermal) federal tax credits expired December 31, 2025. Oklahoma’s co-op rebate programs, especially CKenergy, are now the primary savings vehicle for geothermal installs in 2026:
Federal 25D credit on a $20,000 install
$6,000
Section 25D expired 12/31/2025, Oklahoma utility rebates remain fully active
CKenergy rebate on 3-ton system (2026)
$6,000
$2,000/ton × 3 tons (still active)
For CKenergy members, the rebate math is comparable to what the federal credit offered, and it comes as a direct rebate check from your co-op, not a tax credit that requires you to have sufficient tax liability to use it.
What Hartzell’s Provides to Process Your Rebate
Oklahoma’s electric cooperatives require specific documentation from the installing contractor to process a geothermal rebate. I provide all of it as part of every installation:
- AHRI certification number for the installed equipment
- EER rating documentation confirming the system meets co-op efficiency requirements
- Contractor license information (Oklahoma Master HVAC License)
- IGSHPA accreditation certificate (CKenergy and some other co-ops prefer accredited installers)
- Completion date and system specifications for the rebate application
- Equipment invoice showing equipment and installation cost
I’ve been doing this for 15+ years. When my crew installs your geothermal system, the rebate paperwork is handled. You don’t have to figure it out yourself.
Why Electric Cooperatives Love Geothermal
Electric co-ops like CKenergy are member-owned, they exist to benefit their customers, not shareholders. Geothermal aligns perfectly with their mission: it shifts peak summer cooling load away from the hottest hours (because the ground stays cool), it adds beneficial electric load in winter (heating is electric, not gas), and it keeps member money local instead of going to propane or natural gas companies.
The result is that Oklahoma co-ops actively want to help you go geothermal, and they put real money behind it. CKenergy’s $2,000/ton is one of the highest co-op geothermal rebates in the United States.
Common Questions
How do I find out if I’m a CKenergy member?
Check your electric bill, your utility name and account number are on the bill. If it says “CKenergy” or “CK Energy Electric Cooperative,” you’re in their service territory. You can also call CKenergy at 405-375-4822 to confirm. Alternatively, call me at 405-375-4822. I know the territory and can often tell you which co-op serves your address.
Do I have to apply for the rebate myself?
Most Oklahoma co-op rebates require a member application after the installation is complete. I provide all the documentation you need to submit the application. For some programs, I can submit on your behalf. I’ll walk you through the process at installation time.
Is the CKenergy rebate a check or a bill credit?
CKenergy typically processes geothermal rebates as a direct payment to the member. Contact CKenergy at 405-375-4822 to confirm the current payment method and processing time.
What efficiency rating does my geothermal system need to qualify?
Most Oklahoma co-op programs require the system to meet EER minimums. CKenergy’s program references current IGSHPA and ENERGY STAR standards. I only install equipment that qualifies. I use ClimateMaster systems that meet or exceed all co-op efficiency requirements. Ask me for details on the specific model being installed.
Can I combine the CKenergy rebate with other incentives?
You can only receive rebates from your electric utility (you’re served by one utility). However, if Oklahoma launches the HEEHRA federal rebate program (for low-to-moderate income households, not yet available in Oklahoma), that could potentially stack with co-op rebates. Both the 25C and 25D federal tax credits expired December 31, 2025. Oklahoma utility co-op rebates remain fully active and are stackable with the HEEHRA program when it launches in Oklahoma.
Does the rebate apply to geothermal system replacements or only new installations?
CKenergy’s 2026 program applies to new installations and retrofits (note: the prior replacement unit rebate has been discontinued). Other co-ops like Cimarron Electric offer rebates for both new and replacement geothermal systems. Confirm with your specific co-op which scenarios qualify.

Water Heater + Desuperheater Maintenance
Your geothermal system produces free hot water through its desuperheater, but only if it’s working correctly. Most HVAC and plumbing companies have never serviced one. I inspect the connection between your geothermal heat pump and your water heater to make sure you’re getting every bit of efficiency your system was designed to deliver.
- 🌿 Desuperheater pump operation, flow rate & amp draw
- 🌿 Integration check between desuperheater and backup water heater
- 🌿 Full water heater safety inspection (tank or tankless)
- 🌿 Annual tank flush or tankless descaling (360 plan)
Did you know? A properly maintained desuperheater can offset 50% to 70% of your annual water heating costs. I verify yours is performing to spec during every inspection.
