About Primary Image

Oklahoma's Geothermal Heating and Cooling Authority Since Day One

GES was built on a simple conviction: the right energy solution, done correctly, changes a building's future. We are a geothermal HVAC company, but more precisely, we are a problem-solving company that happens to specialize in geothermal and CNG. What separates us is operational. GES has access to drilling depth, capacity, and expertise that no standalone geothermal installer can match - which means we drill where other geothermal contractors physically cannot go. We design every system to spec, manage financing structures that make projects viable, and stay engaged long after installation through long-term service agreements. The people you meet at GES have been in this work long enough to tell the difference between a system designed to impress on paper and one that will still perform in 30 years. We choose the latter every time. It’s a standard we hold ourselves to on every project, with every client.
