Our Story

American GeoThermal, our parent company, has been apart of the heating and cooling industry since 1981. Locally owned and operated in Murfreesboro, TN – specializing in manufacturing batchwater tank heaters and chillers for the concrete industry.

In 2006, we had identified several barriers within the healthcare community and engineers were looking for solutions! With a team of innovators and big ideas, ChillMaster was born.

We applied our knowledge and expertise to design, fabricate, and test the latest technology on heating and cooling equipment for reliability and ease of operation – without sacrificing quality.

Since then, we’ve expanded our solutions to commercial, industrial, government, and institutional buildings.

Our Mission

Design and build reliable, energy-efficient equipment that meets the challenges our partners face using the latest technologies.

Whether designing for new construction or improving conditions in existing buildings, our team at ChillMaster will meet those challenges with competence and experience!
