Geothermal Heat Pumps in Edmond, Oklahoma

I get calls from Edmond homeowners every summer. It’s always the same story — their existing system runs constantly and the OG&E bill is brutal. Edmond sits in the hottest part of the OKC metro, and with home sizes trending larger, a 3- or 4-ton air conditioner is fighting Oklahoma summer heat from sunup to sundown. Geothermal changes that equation completely. I’m Dave Hartzell — IGSHPA Accredited geothermal installer, ClimateMaster GeoElite Dealer, based in Kingfisher about 35 miles northwest of Edmond.

Why Geothermal Makes Sense in Edmond

Edmond’s newer subdivisions have larger homes with high cooling loads. A ClimateMaster Tranquility 30 geothermal system doesn’t fight 100-degree air — it pulls heat from the ground at a steady 55-60°F year-round. The result is dramatically lower summer bills and the same efficiency advantage in winter. OG&E’s $1,000-per-ton rebate takes the edge off the upfront cost, and the system pays back through utility savings for the next 25+ years.

Ground Conditions in the Edmond Area

Most of Edmond sits on Bethany clay loam — good moisture retention, solid thermal conductivity. In established neighborhoods with larger lots, we can typically run horizontal loops at 5-6 feet deep. In newer subdivisions with tighter lots, vertical bore drilling is the cleaner option — less disruption to the yard, same results. I evaluate each property before recommending a loop design. No cookie-cutter approach.

OG&E Geothermal Rebates in Edmond

OG&E customers in Edmond qualify for a $1,000-per-ton geothermal rebate. On a 3-ton ClimateMaster Tranquility 30, that’s $3,000 off the installation cost. On a 4-ton system for a larger home, $4,000. The rebate is paid directly by OG&E after installation is complete and verified. I’ll handle the paperwork with you — it’s straightforward, and I’ve done it many times.

The System We Install: ClimateMaster Tranquility 30

Every geothermal installation I do uses the ClimateMaster Tranquility 30 — a two-stage scroll compressor system with variable water flow (vFlow technology), iGate DXM2 communicating controls, and R-454B low-GWP refrigerant. It’s ENERGY STAR certified, fully contained indoors (no outdoor condenser to hail-damage or freeze), and warrantied for 10 years on parts and labor from the manufacturer.

I’m a ClimateMaster GeoElite Dealer — one of a small number of contractors in Oklahoma with this certification. It means I have direct access to factory training, technical support, and warranty processing. It also means I’m accountable to ClimateMaster’s quality standards on every install.

Ground Loop Options for Edmond Properties

• Horizontal closed loop — Trenches at 5-6 feet depth, 400-500 feet of loop per ton. Best for properties with adequate yard space. Lowest installation cost.
• Vertical bore — Bores drilled 200-300 feet deep per ton. Smaller surface footprint. Right choice for tighter lots or landscaped yards where trenching isn’t practical.
• Pond/lake loop — If you have water access, a submerged loop is often the most cost-effective option. Less excavation, excellent heat exchange.

I evaluate each property and recommend the loop configuration that fits the site. No one-size-fits-all approach.

Frequently Asked Questions

Does OG&E offer geothermal rebates in Edmond?

Yes. OG&E pays $1,000 per ton for qualifying closed-loop geothermal installations. A 3-ton system earns a $3,000 rebate, a 4-ton earns $4,000. The rebate is paid by OG&E after installation and verification. Hartzell’s handles the rebate paperwork.

What size geothermal system does an Edmond home need?

Most Edmond homes need 3-4 tons depending on square footage, insulation, and construction. I do a proper Manual J load calculation before recommending a size — right-sizing matters. An oversized system short-cycles and an undersized one runs constantly. Neither is efficient.

Is the soil in Edmond good for a geothermal ground loop?

Yes. Edmond sits on Bethany clay loam with good moisture retention, which improves thermal conductivity. Horizontal loops work well on larger lots. Vertical bore drilling is available for tighter subdivisions. I evaluate each property individually.
