Oklahoma’s Geothermal Hub: IGSHPA Accredited, Have Experience, Will Travel
Geothermal is not complicated if you know what you are doing. I have been installing ground source heat pump systems for 15 years across central Oklahoma. I am IGSHPA Accredited, a ClimateMaster GeoElite Dealer, and I handle the CKenergy, OG&E, and OEC rebate paperwork so my customers get every dollar they are owed. I serve all of central Oklahoma. Have experience, will travel.

Where I Work
I install and service geothermal systems across all of central Oklahoma. Kingfisher County is my home base, but geothermal installs are large projects and worth the drive. I have completed installations in Blaine County, Canadian County, Garfield County (Enid), Major County (Fairview), Logan County, and beyond. If your utility has a rebate program, I make the trip.

Why IGSHPA Accreditation and ClimateMaster GeoElite Matter
IGSHPA Accreditation is the ground source heat pump industry’s professional certification. It covers loop sizing, system design, and installation standards. The coursework and field evaluation are specific to geothermal, not general HVAC. Most HVAC shops hold a state mechanical license and nothing else. IGSHPA Accreditation means I have been tested on the actual science of how ground loops work and how to size them correctly for Oklahoma soils.
ClimateMaster GeoElite is the top dealer tier with ClimateMaster, the leading American geothermal manufacturer. It means direct factory support, priority parts access, and access to the best equipment warranties available. In 2016, Air Products Supply, ClimateMaster’s regional distributor, named Hartzell’s “Best Newcomer of the Year” across their entire dealer network.
Rebate paperwork: I have completed the CKenergy, OG&E, OEC, and Cimarron Electric rebate applications many times. I handle the paperwork so my customers never leave money on the table. A CKenergy rebate on a 5-ton system returns $10,000. That is not money you want stuck in a bureaucratic form.
Manufacturer Training and System Design. I am not just a ClimateMaster dealer. I am factory-trained, which means I have been through ClimateMaster's technical curriculum on system design, loop field sizing, and installation standards. I also do the full system design in-house, including Manual J load calculations and loop field layout, before a single hole is drilled. Most HVAC shops outsource that or skip it. I do not.
Geothermal Questions
How far do you travel for geothermal installs in Oklahoma?
Anywhere in central Oklahoma. A geothermal system is a significant investment and deserves the right installer. I have driven to Watonga, Fairview, Enid, and beyond. The rebate money usually covers the difference. Call 405-375-4822 and tell me where you are.
How much is the CKenergy geothermal rebate in Oklahoma?
$2,000 per ton of system capacity, up to $24,000. A 3-ton system returns $6,000. A 5-ton system returns $10,000. CKenergy covers 10 counties including Blaine, Canadian, Custer, and Grady. I handle the application for you.
Do you install geothermal systems in Enid Oklahoma?
Yes. I serve Garfield County including Enid. OG&E offers a $1,000 per ton rebate for geothermal in that territory. Call me for a free site assessment and I will tell you exactly what the system will cost after the OG&E rebate.
What is the difference between IGSHPA Accreditation and a regular HVAC license?
A Master HVAC license covers the mechanical and refrigeration side of heating and cooling equipment. IGSHPA Accreditation is specific to ground source heat pump systems, covering loop field design, soil thermal conductivity, system sizing, and installation standards. Not all Master HVAC technicians have it. In Oklahoma, very few do.
Is the Section 25D federal tax credit still available for geothermal in 2026?
No. Section 25D expired December 31, 2025. It is no longer available for new installations. The good news is that Oklahoma utility rebates, including CKenergy at up to $24,000, are still fully active for 2026 installs. That is the money to focus on.
What Our Customers Are Saying
4.8 stars • 271 verified Google reviews
Financing available. Geothermal systems are a significant investment and the right time to do it is when the rebate window is open. I offer financing through Synchrony, Wells Fargo, and Wisetack. Many of my customers finance the out-of-pocket portion after the utility rebate and pay less per month than they were spending on gas and electric.
