Energy Dynamics
121 W. Hoyt St, Carthage, South Dakota, United States

Energy Dynamics, Inc. was founded in 1995 as the exclusive distributer of the Hydron Module product line back when it was manufactured by the Millbrook Hutterite Colony.  In 2007, Enertech MFG acquired Hydron Module and began manufacturing that line as well as the GeoComfort line at a facility in Mitchell SD.  We picked up the GeoComfort brand at that time and continue selling it and the Hydron Module line to this day.  We are very proud of our long history selling and supporting geothermal systems and doing our small part to grow the industry.  In order to better serve our dealers we have diversified our product offerings in recent years however our niche focus has remained on renewable and high efficiency systems.        

Our Mission

Our mission is to provide you with the best products and service in the HVAC/R industry.  In order to accomplish this we work to stay on the front edge of system design and technical details of our products.
