The oldest brand of residential geothermal systems, TETCO was founded in 1977. The makers of TETCO products have always been dedicated to the geothermal concept and continue to demonstrate passion for the technology in the design features of the TETCO product line. Environmentally conscious homeowners were installing TETCO geothermal heat pumps before the term “geothermal heat pump” was even being used, thus the name TETCO (Thermal Energy Transfer Company).
