Geothermal is a design job before it is an install.
The loop, the ductwork, the water side, the electrical service and the startup numbers decide whether a geothermal system performs. I plan it from the house load outward, and I travel most of Oklahoma for geothermal.

What I need before I size anything
- Home loadManual J, windows, insulation, air leakage, orientation, design temperature. Oversizing raises cost and short cycling. Undersizing leans on backup heat.
- Ducts and airflowStatic pressure, return size, supply layout. Geothermal cannot fix a duct system that cannot move the air.
- Loop fieldHorizontal, vertical, pond or open loop, and whether the site allows it. The loop usually decides the project cost.
- EquipmentCapacity, staging, controls, flow center, desuperheater and electrical requirements, matched as one system.
- Money pathCash, financing, the Geothermal Comfort Plan, and any utility rebate verified by service address first.
- Existing loopOn a replacement, the first question is whether the ground work survives. Reusing a loop
Loop first, nothing buried untested
- Loop workThe loud, messy part. Bores or trenches, pipe fused, pressure tested and flushed.
- Equipment and flow centerThe heat pump, pumps and controls set and matched to the loop.
- Duct tie-in and electricalConnected to ductwork that can actually move the air.
- StartupEntering and leaving water temperature, loop pressure, flow, airflow, electrical draw.
- Commissioning recordA written startup record handed to you. If a quote does not show it, ask why.
What it should show you
The work
Equipment, loop method, flow center, controls, electrical scope, duct tie-in, startup, commissioning and documentation.
Written scopeExclusions
Landscaping restoration, utility upgrades, unusual drilling conditions, well-water treatment, duct rebuilds, owner add-ons.
Named up frontWhat drilling does to a yardCommissioning
EWT and LWT, loop pressure, flow, airflow, electrical draw, control operation, written startup record.
Your baselineThe commissioning recordBefore you compare prices, see what an Oklahoma geothermal install actually costs. Paying over time: the Geothermal Comfort Plan or financing.

Straight answers
How much does geothermal installation cost in Oklahoma?
The loop field is usually the number that decides it, so I will not quote it sight unseen. New system estimates are free anywhere in Oklahoma, and my cost page shows the ranges and what moves them.
What happens on installation day?
The loop work comes first, and it is the loud, messy part. Then the equipment, flow center, controls, duct tie-in and startup. Nothing gets buried until it holds pressure.
Will drilling tear up my yard?
It makes a mess while it happens and I will not pretend otherwise. Vertical bores disturb less ground than trenching. The drilling itself is done by my OWRB-licensed driller.
What should a complete geothermal quote show?
Equipment, loop method, flow center, controls, electrical scope, duct tie-in, startup and a written commissioning record. If the commissioning proof is missing, ask why.
Is the estimate for a new system free?
Yes. A diagnostic on a system you already own is the $348 flat geothermal diagnostic, which is a different visit.
