December 20, 2016 | Jody A new age of Geothermal is on the horizon, and it’s called Direct Exchange Geothermal. My issues with standard Water to Air Geothermal is the mess and the cost. This newer technology allows for cleaner, less invasive, longer lasting installs. The biggest advantage is that it costs less per ton. We are now certified to install this technology and look forward to assisting our Lowcountry Clients who are on their way to a more efficient use of energy.
