MN Geothermal, situated in Zimmerman, MN, is owned by Jason Massmann, who has been involved in designing and installing Geothermal systems since 1995.  Jason decided to start his own company, Massmann Geothermal & Mechanical, LLC, in 2002.  Jason worked diligently to grow his company and earn the business of many homeowners throughout Minnesota.  He earned numerous awards from Geocomfort throughout the years, including Dealer of the Year and Sales Champion, many times over. By 2019, Massmann Geothermal & Mechanical, LLC had grown to 18 employees. In 2021, Jason was approached about selling his business. After much thought, mostly about missing out on family time, he decided it was going to be a good opportunity for him & his family.  The new owners soon took over under the same name.  Jason continued his passion designing geothermal systems, but with Enertech, a heat pump manufacturer. He was able to work with contractors throughout the US and Canada. By 2025, the company he sold was closing its doors. Jason wanted to take care of his old customers and decided to get back into the business side and started up MN Geothermal. Jason, his wife, and three kids reside in Zimmerman, MN.
