Hi Tech Geothermal Heating 930 Chapman Drive, River Falls, WI 54022

"Very prompt and professional service every time. Dennis is passionate about geothermal and definitely knows what he is doing. He went the extra mile and gave me more than my money's worth, getting my heat back on within 3 hours of calling him. He genuinely cares about his customers!"

"Dennis has helped us a number of times to repair and upgrade our Econar (now Geo Comfort) heat pump installation for our home geothermal system. I have not met anyone else in this field that knows more about how these systems work and the best options for maintaining or upgrading the equipment. He's done compressor repair, new thermostat installation, and just recently a complete upgrade to a newer heat pump unit for us, and I would not consider calling anyone else at this point to seek help for this. He's always responded quickly about questions or service and was always on time and got the work done without any worries. I absolutely recommend Hi Tech for anyone looking for installation, repair or upgrade of their geothermal setup."

"Dennis quickly responded and fixed our Geothermal system so it would cool our home. He also took the time to educate me on the system and how it works, we bought the home with the geothermal already installed. Hi Tech Geothermal will be the only ones to service my system."

"Always professional, prompt and friendly service! A great company!"
