Welcome To GeoComfort

Steve Smith
CEO, Founder

Our leadership team is unlike any other, starting with our CEO, Steve Smith, whose roots run deep in the geothermal industry and whose care for customers, dealers, distributors, and employees can't be beat.

In 1983, Steve was introduced to geothermal heat pumps as Director of Member Services for an electric cooperative in southwestern Illinois, and later, he assisted in the start-up and management of a geothermal distribution company owned by a group of electric cooperatives.

With a mission to take care of his customers, Steve and his wife, Karen, started Enertech Inc., a dedicated geothermal systems distribution company located in Greenville, IL. The company purchased a manufacturing facility in Mitchell, South Dakota in 2007 to manufacture geothermal heating and cooling brands, including GeoComfort Geothermal Systems. Enertech Inc. grew to become Enertech Global, and the company and its brands are now part of NIBE Climate Solutions.

Steve advocates for the geothermal heating and cooling industry as a whole, serving as a member of the Geothermal Exchange Organization, actively participating in speaking engagements, and sharing his expertise in articles, but his favorite place to be is in the field helping with an installation or solving problems.

"We spend approximately 4,000 to 6,000 hours per year in our homes. You deserve to be comfortable and experience energy savings for these hours, and we're here to make both of those things happen. When you get a GeoComfort system, you join our family."

Why GeoComfort?

GeoComfort Geothermal Systems are proudly built with the highest standards of quality in the heart of America, Mitchell, South Dakota. Our commitment to continuous improvement and quality control has made reliability one of the GeoComfort brand's greatest assets. Many heating and cooling brands claim to have the most thorough testing. We actually do. Each GeoComfort Geothermal System is ran and monitored before it leaves our factory. We stand behind our systems with the best warranty in the industry.

Our specialized component selection and advanced design gives GeoComfort Geothermal Systems a competitive advantage. An industry first, all of our vertical-packaged units have micro-channel air coils, preventing corrosion for a longer lifespan and further reliability. ECM blower motors are standard on all GeoComfort equipment. These variable-speed motors ensure quiet start-up and operate at a fraction of the cost of a conventional blower motor.

GeoComfort systems give you more. Hot water generators are standard with all GeoComfort geothermal units which allow you to capture unused heat and apply it to water heating, typically cutting hot water costs by 25 – 40%. Unit for unit, our systems have higher heating capacities than our competitors, which means lower heating costs when compared with other geothermal brands.

When you purchase a GeoComfort Geothermal System, you become a member of our family, and this family is dedicated to making sure your system keeps you comfortable for its lifetime.

Enertech, manufacturer of GeoComfort geothermal systems, is recognized by industry trade associations and certified for compliance with safety and efficiency standards. Our systems have also received multiple industry design awards.
