Rising energy bills and unreliable HVAC have a permanent answer. GES is Oklahoma's trusted geothermal heating and cooling contractor - delivering geothermal systems that cut operating costs for decades and CNG solutions that reduce fuel expenses for fleets across the state.
GES exists to reduce the operational burden of energy costs for Oklahoma businesses, schools, and public institutions, permanently. We design, drill, and install geothermal HVAC systems that deliver decades of reliable, predictable performance, and we convert vehicle fleets to CNG so organizations can cut fuel costs without cutting corners. Our mission is not a transaction; it is a long-term partnership grounded in integrity, expertise, and results that speak for themselves.
A future where every energy-intensive facility in Oklahoma operates with the stability and cost predictability that geothermal makes possible, and every fleet runs cleaner and cheaper on CNG. A future where smarter energy is the trusted standard, not the exception, and where the organizations we work with can redirect savings toward the people who depend on them.
or more in utility savings - that is what geothermal systems consistently deliver, along with significantly lower long-term maintenance costs.
completed and counting - backed by more than 20 years of geothermal experience and a decade of CNG solutions across Oklahoma.
fuel cost reduction is achievable for Oklahoma fleets through CNG - and GES has the installations to prove it.
Geothermal heating and cooling in Oklahoma is not a trend. It is infrastructure - the kind that lasts 50 years underground while the world above keeps changing. Rising utility costs, aging equipment, and unpredictable maintenance cycles are problems that conventional commercial HVAC systems manage at best. Geothermal eliminates them. The ground below your facility maintains a stable temperature year-round, and a properly engineered geothermal heat pump installation harnesses that stability to heat and cool your building at a fraction of the operating cost of traditional equipment. When you factor in geothermal HVAC cost over a 20- to 30-year window, the case becomes difficult to argue against.
For organizations running vehicle fleets, CNG solutions offer one of the clearest cost-reduction opportunities available today. Compressed natural gas burns cleaner than diesel and costs significantly less per mile. GES has converted hundreds of vehicles across Oklahoma and installed fueling infrastructure at facilities statewide, giving fleet operators a complete, on-site solution with immediate, measurable savings.
As one of the most experienced geothermal heating and cooling contractors in Oklahoma, GES handles the complexity that stops most operators before they get started - financing, permitting, geothermal HVAC installation, and long-term service agreements, all under one roof. Our geothermal drilling contractors have the in-house capacity to drill where others cannot, making commercial geothermal installation viable for projects that other geothermal HVAC companies in Oklahoma would walk away from. We also provide ongoing geothermal HVAC service and geothermal heating and cooling repair long after installation, because a system that performs for 50 years requires a team that stays engaged for 50 years.
If your facility runs on unpredictable energy costs, that is a problem we know how to solve. And we have the energy efficient commercial HVAC installations across Oklahoma to prove it.
"Having geothermal was a game changer for our entire community."
"GES delivered exactly what we needed — an energy-efficient geothermal system that saves us money, keeps our classrooms comfortable, and makes life easier for our maintenance team. Five years later, it's still performing great."
"GES helped us save $800,000 in cost and make our bond whole again."
“We have seen significant savings on our fuel bill.”
GES is based in Goldsby, Oklahoma, with geothermal HVAC service coverage spanning the entire state. We work across metro areas, rural communities, and everything in between - licensed to serve clients in parts of Arkansas and North Texas, with Kansas expansion coming soon.
We start by understanding your facility, your current energy spend, and your goals. A thorough assessment gives us the data to design a system that actually delivers - and lays the foundation for a partnership built to last.
Our engineers design a geothermal system matched precisely to your building load. We handle the well field design, mechanical layout, and financial structuring - including available incentives and service agreement options.
Our crews drill where others cannot. Every well is drilled and inspected to spec. Installation is coordinated with your schedule to minimize disruption and ensure a clean, complete handoff.
We do not disappear after the final invoice. GES remains your partner through service agreements, performance monitoring, and ongoing support, because a system that performs for 50+ years requires a team that shows up for 50 years.
Geothermal is still new to most facility managers and building owners. These are the questions we hear most often, answered plainly.
