The loop field can fit under your parking lot.
You already own the land the system needs. My licensed driller may be able to drill the bores where you park, depending on the site. I set the loops and put the surface back, and the equipment lives inside the building where hail and copper thieves cannot get to it. Running a duplex or small apartment building? Here is how I price geothermal for small multifamily.

Your lot can be where the loop field goes
A commercial bore field does not need a field. It needs depth, and depth is straight down under whatever is already there. The parking lot, the drive or the side yard can be where the loop field goes, depending on the site, and I walk the site with you before I quote.
- Your parking lot may workVertical bores tied into a common header, with the header trench running to the mechanical room. The depth and number of bores come from my load calculation and the site.
- The surface comes off and goes backSaw cut, drill, set and grout the loops, pressure test, backfill, then patch the surface over the work.
- Nothing outside to wreckNo rooftop units cooking in August sun, no condensers to hail-dent or strip for copper. The machinery is indoors.
- Quiet where it countsThe noise is in a mechanical room, not outside a classroom window or a patient room.
- Per zone control at scaleWater source heat pumps let a gym, a server closet and an office wing run their own setpoints instead of fighting one air handler.
There is an IRS credit for businesses that own their geothermal
It is an IRS business tax credit program, and it applies to geothermal on any business that depreciates the property: an office, a shop, a barn, a daycare, a bar, a coffee stand. There is no minimum size. How to get it is a conversation, not a web page. Call me at 405-375-4822 and I will walk you through it.
Available to businesses that depreciate the property. Your tax professional confirms eligibility. Talk to your tax professional to confirm it for your business.
I am an HVAC contractor, not your CPA. I will tell you how the system is built and what it costs. Your tax professional confirms what qualifies for your project.




Does the credit pay for my new parking lot?
Owners ask whether the credit covers the lot work. I will not tell you it does. What counts toward the credit is your tax professional’s call, and I would rather you hear that from me than from your accountant after the fact.
For a commercial building, let us talk ownership
Buy the system
You own the equipment and you hold the depreciation. Call 405-375-4822 and I will go over the ownership and payment options for your project, and how the IRS business credit fits.
You own itBuy, and ask me about your route
Tax exempt owners have a route of their own. Call 405-375-4822 and I will walk your board or your finance office through it. Your tax professional confirms what applies to you.
Ask meThe Full Coverage Geothermal Plan lease
Hartzell’s Full Coverage Geothermal Plan is a ten year lease through Palmetto with nothing upfront, its coverage subject to the terms of the contract. It is for residential geothermal only and caps at $200,000 a project, so it is not the path for a commercial building.
Lease, not a loanHow the Full Coverage Geothermal Plan worksOn the lease: it is a residential program only. Call 405-375-4822 and I will go over the options for your commercial project.
From small offices to large commercial buildings
A small office and a large building get the same discipline. What changes at scale is the loop design and how much load calculation the job deserves.
- Schools and campusesDistrict scale heating and cooling with per zone control a boiler and chiller plant cannot match, and no rooftop units baking on a gym roof.
- Hospitals and clinicsQuiet, steady, redundant capable systems for buildings where temperature and humidity are not optional.
- Municipal and governmentCity halls, libraries, fire stations, water treatment buildings. I can walk your board through the options.
- ChurchesA sanctuary that sits empty six days and packed on Sunday needs a system that handles swing load without running full tilt all week.
- Offices and retailPredictable comfort, low mechanical noise, and nothing on the roof for a storm to chew up.
- Agricultural and industrialProcess cooling, dehumidification and conditioned work space where the load looks nothing like a house.




The loop is where the engineering time goes
- Vertical bore fieldsThe standard answer on a tight site or a campus. Multiple bores tied into a common header, sized to your measured peak load. An undersized bore field can cause poor performance, which is why I size it to your measured load.
- Pond loopsIf you have a pond or a deep enough retention feature, a closed pond loop can be an option. Whether it works depends on the site and the load, and I check both before I quote.
- Standing column wellsWhere the geology supports it, water circulates through the well itself rather than a sealed loop. It depends entirely on the aquifer and on water rights, and not every site qualifies.
Geothermal is statewide for me, not a Kingfisher only service. I bring the load calculation and the loop design and coordinate the drilling through my licensed driller, so you manage one contractor instead of three.
Six steps, documented at each one
- Load calculationReal heating and cooling load for your building, not a square footage guess. Every decision after this one depends on it.
- Geology and site assessmentSoil and rock, available ground, pond depth if a pond is on the table, water rights if a standing column is.
- Loop and bore field designEngineered to your load and documented before anyone drills.
- Drilling and civil coordinationI coordinate the drilling and the surface work so you manage one contractor, not three.
- Equipment installClimateMaster commercial water source heat pumps, staged and distributed to match your zoning plan.
- Commissioning and documentationLoop pressure test, performance verification, written down, not verbal, and the link to register the warranty. Your CPA gets the cost detail in whatever form they want.



Commercial geothermal questions I get
Is there a tax credit for commercial geothermal?
Yes. It is an IRS business tax credit program for geothermal on property your business depreciates. Call 405-375-4822 to learn how. Your tax professional confirms eligibility.
Does the credit pay for my new parking lot?
I will not tell you it does. What counts toward the credit is your tax professional’s call.
How much of the lot do you have to tear up?
Enough to drill the bores and run the header trench to the building. My licensed driller does the drilling. I design the loop, then it is set and grouted, pressure tested, backfilled, and the surface is patched over the work. Once the job is finished the loop field sits under the lot, but how much of your lot is affected while the work is under way, and whether any parking spaces are, depends on the site. I walk it with you before I quote.
What does it cost to have you look at my building?
The consultation is free. Weekends are open for it as availability allows. On a weekday I start with a phone call and ask for your utility bills first, then I set the visit. If you want me diagnosing an existing commercial system rather than planning a new one, call 405-375-4822 and the office will confirm the price for your system.
Can a school, a city or a church get a tax benefit?
Tax exempt owners have a route of their own. Call 405-375-4822 and I will walk your finance office through it. Your tax professional confirms what applies to you.
Should I lease it instead of buying it?
The Full Coverage Geothermal Plan, a lease through Palmetto, caps at $200,000 a project and is for residential geothermal only. Call 405-375-4822 and I will go over the options for your commercial project.
Do you work outside Kingfisher County?
For geothermal, yes. I take loop jobs across Oklahoma and most states that border it, and I service them after, as availability allows. Out of state, what I can do depends on that state’s licensing, so call 405-375-4822 and I will tell you. Everyday air conditioning, heating and water heater work stays inside my seven counties.
Tell me what you are running now
Square footage, what is on the roof, how old it is, and whether your lot needs work anyway. I will tell you whether geothermal fits the building before either of us spends money on a design.
Call 405-375-4822Free consultations Saturday and Sunday, anywhere in Oklahoma, as availability allows. Everyday commercial service runs across Kingfisher, Canadian, Oklahoma, Garfield, Major, Logan and Blaine counties. For geothermal installs, and only for geothermal, I also travel to most states that border Oklahoma.
