Geothermal Retrofits More and more residents in Lancaster are realizing just how great geothermal systems are for retrofit or replacement applications. The benefits are obvious: Geothermal systems are counted as one of the most dynamic, energy-saving, eco-friendly heating and cooling solutions in the industry today. Most geothermal units are simple to put in - particularly those replacing another forced-air system. Geothermal systems can be installed in areas where fossil fuel furnaces are unfitting. That's because, with geothermal, there isn't any combustion and therefore no need to vent exhaust gases. Geothermal technology is perfect for in-floor radiant heating, because heated water circulates throughout pipes underneath your floors to heat your rooms.
