Geothermal Sales & Service Inc.

We are a small, family-owned geothermal heating and cooling specialist established in 1995. Located at 4707 County Road 45 in Auburn, Indiana, we focus specifically on geothermal systems for residential and light commercial properties. Our work includes new construction, replacement systems, and retrofits or conversions. Whether a project begins with a new design or an existing system needs to be replaced, we design it from the ground up.

We design, install, and repair geothermal loop systems, including open loops and closed-loop configurations. Our closed-loop work includes horizontal, bored, vertical, and pond loops. We install all our own loops, allowing us to take a direct role in both system design and loop installation. We service all brands, makes, and models of geothermal equipment. As a Climatemaster GeoElite dealer, we install Climatemaster equipment while also working with geothermal systems from other manufacturers.

Integrity, workmanship, and customer satisfaction are central to how we approach every project. We are proud of our A+ rating with the Better Business Bureau and remain committed to delivering high-quality installations. Our mission is to install efficient geothermal heating and cooling systems using the best installation practices on every project we undertake. From initial design and loop installation to equipment service and loop repairs, we bring the focused approach of a geothermal specialist to our work.
