Geothermal Retrofits More and more residents in Alaska are learning just how great geothermal systems are for retrofit or replacement applications. The benefits are easy to see: Geothermal systems are counted as one of the most dynamic, energy-saving, environmentally friendly heating and cooling solutions in the industry today. Most geothermal units are a breeze to to place in your home - particularly those replacing another forced-air system. Geothermal systems can be installed in areas where fossil fuel furnaces are unsuitable. That's because, with geothermal, there isn't any combustion and thus no need to vent exhaust gases. Geothermal technology is ideal for in-floor radiant heating, because hot water radiates through pipes below your floors to heat your rooms.
