Geothermal country, 25 miles from my shop.
Piedmont sits in the growth corridor between Kingfisher and Oklahoma City, and the lot sizes out here are exactly what makes a ground loop practical. I am IGSHPA accredited, I size the loop myself, and a geothermal diagnostic is $348 flat whatever the hour.

More than half the Piedmont homes I work for run on geothermal
I have completed 60+ jobs at Piedmont addresses since 2017, for 20+ households, and more than half of those households heat and cool with the ground. Nearly half of my visits here are on a geothermal system. The numbers below explain why.

Newer houses on bigger lots, a good share of them out past the gas lines. That is the recipe for ground-source heat. Most of what I do on a Piedmont geothermal system is the loop side: pressurizing and flushing the field, replacing pump modules and flow centers, and checking flow before anybody blames the heat pump. The rest of my Piedmont tickets are the usual summer pair: condensate drains and capacitors.
Piedmont sits mostly in Canadian County and reaches into the south edge of Kingfisher County. I run both every day, and the drive from my shop is about 28 miles by road, roughly 35 minutes.

Land, soil, and a co-op rebate that is actually live
Most of Oklahoma cannot make geothermal pencil because the lots are too small to trench and drilling a vertical bore on a quarter acre gets expensive fast. Piedmont is the opposite problem to have: acreage, room to lay a horizontal field, and soil that behaves.
The other half is the co-op. Piedmont straddles service territories, and if CKenergy is the name on your power bill their geothermal rebate is $2,000 per ton, capped at $24,000, effective January 2026, and retrofits qualify as well as new installs. They also run a fixed 6 percent loan over four to seven years on energy work. If OG&E bills you instead, their Oklahoma residential rebates are closed for 2026 and expected back in 2027. Same house, same equipment, completely different money, which is why I ask who bills you before I say a number.
I will not quote a rebate figure off the top of my head. Tell me the name on the bill and your address, and Shelby or I confirm the live program first. Free evaluation, consultation and sizing on Saturday and Sunday.
Piedmont houses, and what goes wrong in them
Piedmont is ranch homes and acreage builds next to fast new construction, and the two fail in completely different ways.
- Builder-grade systems sized off a spreadsheetNew builds out here get sold with equipment picked from a table rather than a load calculation. Three years later the house cannot hold temperature in August and everyone blames the unit. I run the numbers before I quote a replacement.
- Loop pump modules and flow centresOn an existing geothermal system this is the part I am called to most: flow, pressure and the pumps that move it. The photos below are a Piedmont loop pump upgrade.
- Heat pumps stuck in coolingReversing valve or a control that was never set up for a heat pump. The house never warms.
- Acreage properties on well waterWhere there is already a good well, an open loop is worth costing out against a closed field. It does not suit every place and I check yield and water quality before I say so.
- Long duct runs in wide housesSingle storey, spread out, and the far bedroom never keeps up. Usually a static pressure and return air problem rather than a tonnage problem.
- Storm damage and surgeOpen country means lightning. A control board or a compressor lost to a spike is a bad week, and surge protection is cheap by comparison.

IGSHPA accredited, ClimateMaster GeoElite. Loop design, sizing, install and service. Free Geothermal Consultation on weekends, and for geothermal I travel across Oklahoma and most bordering states.
Diagnostic $348 flatWhat a geo visit coversRepair
Every major brand, common parts on the truck, a written price before the work and a six month labor guarantee on the part I replaced.
$210 flat, $309 after hoursBuilders
Manual J on every house, equipment sized to the plan rather than the price list, and duct designed before it is installed rather than after it fails.
Estimate freeReplacement and new systemsWondering whether to fix it or replace it? Run the repair or replace calculator, or get a second opinion on a replacement quote, which is handled like an estimate. Checking another company’s repair diagnosis is my regular service call, $210, and the $210 comes off only if you buy a new system from that visit. Weekends and after hours it is $309 and geothermal is $348 flat, and neither of those is credited. New-system estimates are free. I measure the house and give you a written price, no pressure.

Loop alarms, lightning, and what is safe to check
- A geothermal loop or flow faultWrite down the code and call me. Do not keep resetting it, and never open the loop, add antifreeze or bleed a line. A low-flow fault run over and over is how a heat exchanger freezes.
- After a lightning stormIf the system is dead and the breaker has not tripped, a board or a surge protector may have taken the hit. Leave the panels closed and call.
- Gas smell or a carbon monoxide alarmGet everyone outside first and call 911 or the gas utility from there. Do not touch switches, the thermostat or breakers on the way out. Then call me.
- Safe for you to checkThermostat mode and setpoint, the filter, a tripped breaker (once), closed registers, and anything blocking an outdoor unit.
Who covers what on a Piedmont job
On a repair, my labor guarantee is six months on the part I replaced and on my work on it. If that part or my work fails inside six months, I come back and fix it at no charge. A different part failing, or a leak in a different spot, is a new problem and a regular service call. Parts carry their manufacturer’s warranty, and I buy parts with a 1-year warranty whenever one is available.
On a new system, my install labor warranty is two years on Trane systems rated 17 SEER and up and on geothermal, and one year on everything else. The longer manufacturer parts warranty is yours to register: Trane gives you 60 days from install and Mitsubishi 90. My post-install email sends you the link. It takes a few minutes, but it has to be you who fills it in.
A commuter town that kept its acreage
Piedmont started small and rural and stayed that way a long time, which is exactly why it is growing now: it is close enough to Oklahoma City to commute and far enough out to have land. That combination is what fills the new subdivisions on the south and east sides while the older places out toward the county line still sit on acreage.
For me that means two service calls that look nothing alike. One is a four year old house where the builder’s system was never sized for the west-facing glass. The other is a place on ten acres with a geothermal system somebody installed well in 2009 and nobody has flow-tested since. I am about 25 miles up the road in Kingfisher, Canadian County is on the daily route, and I would rather drive it than tell you to wait three days for a company coming out from the metro.
Straight answers
Am I on CKenergy or OG&E in Piedmont?
It depends on your exact address, because the territories interleave around Piedmont. It matters: CKenergy’s 2026 geothermal rebate is $2,000 per ton up to $24,000 and retrofits qualify, while OG&E’s Oklahoma residential rebates are closed for 2026 and expected back in 2027. Read the name at the top of your power bill and I confirm the live program before quoting.
How much does a geothermal service call cost in Piedmont, Oklahoma?
$348 flat, weekday or after hours, for every customer including plan members. That covers loop pressure and flow, refrigerant charge, desuperheater, controls and the heat exchanger, with a written report and quote before I leave. It is not credited toward the repair.
My geothermal unit in Piedmont is showing a flow or loop alarm. What do I do?
Write down the code and call 405-375-4822. Do not keep resetting it, and do not open the loop or add anything to it. Repeated low-flow lockouts are how a heat exchanger gets damaged.
My Piedmont house is only a few years old and the AC cannot keep up. Why?
Almost always sizing. Production builders pick equipment from a table, and a house with west-facing glass and high ceilings does not behave like the one the table assumed. A Manual J load calculation tells us whether it is undersized, whether the duct is the real problem, or both, before you spend money replacing like for like.
What does a regular AC or furnace call cost in Piedmont?
$210 on a weekday: $99 dispatch plus $111 diagnostic, not credited toward the repair. Evenings, nights, Saturday and Sunday are $309. The repair is quoted in writing before I start.
Is Piedmont in Canadian County or Kingfisher County?
Both. Most of Piedmont is in Canadian County and the north side reaches into Kingfisher County. I run both counties every day from my shop in Kingfisher, about 28 miles away by road.
Do you have a maintenance plan for geothermal in Piedmont?
Yes. Geo One Visit Spring or Fall 360 is $360 a year, Geo Spring and Fall 360 is $428 and Geo Full Year 360 is $499. A one-off geothermal tune-up is $348. Plan visits go on my route with a general date and week agreed with you.
Do you work with builders on new construction in Piedmont?
Yes. Load calculation on every house, equipment sized to the plan, and the duct designed rather than improvised. It is far cheaper to get it right before the drywall goes up.
Tell me what it is doing
Warm air, ice on the lines, a loop that will not hold pressure, or a new build that never kept up. Describe it and I will tell you straight what I think it is before I drive out. Free geothermal consultations Saturday and Sunday.
