Bring the comfort of the earth into your home

The TETCO product line was founded in 1977 by individuals dedicated to the geothermal concept. In fact, homeowners were installing TETCO geothermal heat pumps before the term was being used.

The name TETCO stands for Thermal Energy Transfer Company, and it shares a rich history of manufacturers demonstrating passion for its design. In the 1990s, this outstanding product line was purchased by the family-owned Edwards Engineering Corporation. The original owners of TETCO were operating Chiller Solutions LLC, a manufacturer of HVAC & process chillers. In 2003, they re-acquired the line when they purchased all the assets of Edwards Engineering.

TETCO was then acquired by Enertech in July 2009. Units are now being produced in Enertech's state-of-the-art production facility in Mitchell, South Dakota.
