Welcome Home

When it comes to choosing a geothermal manufacturer, you have options. But only one option that treats you like family. See our story and our philosophy for building great products.

Come Home... to family

When Enertech first began in 1996, it was with one simple philosophy: People come first. Since that day, that’s exactly what we’ve been doing, and we now manufacture great brands such as GeoComfort, Hydron Module, and TETCO. As a people-centric company, we believe in family values, loyalty beyond reason, assurance in quality craftsmanship, and making the world a better place. That’s our roadmap, carefully guiding every decision we make. In fact, it’s more than just what we believe; It’s simply who we are.

The heart of every system... begins with great products


GeoComfort units are made in America with the highest standards of quality. Our commitment to continuous improvement and quality control has made reliability one of GeoComfort's greatest assets. No other geothermal manufacturer has quality testing as extensive. In fact, each and every GeoComfort unit undergoes rigorous testing before it is packaged for shipping.


The Hydron Module brand is founded on the basic principle of quality craftsmanship. From inception, Hydron Module geothermal systems have been built with the simple idea of good people taking pride in producing the best products. Reminiscent of a time when a person's word meant something, Hydron Module geothermal systems demonstrate integrity by carrying the industry's best warranty.


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).

We also own several legacy brands.

What Happens to the Suns Energy

Geothermal heating and cooling is all about harnessing the power of the earth and utilizing it to transfer heat. Much like a refrigerator, a geothermal system has the ability to move heat from one location to another. With the earth absorbing 48% of the sun’s solar energy, the result is a fairly constant underground temperature of 45 degrees in northern climates to 70 degrees in southern climates.

Through pipes buried in the ground, we transfer heat from the earth to a home in the winter, then reverse the process by pulling heat from the home in the summer and releasing it into the cooler ground during the summer months. The result is the most comfortable living environment imaginable that is both eco-friendly and provides substantial cost savings on utility bills. It’s an all-around win for every homeowner.
