Geothermal Retrofits More and more residents in Mt. Pleasant are realizing just how great WaterFurnace geothermal systems are for retrofit or replacement applications. The benefits are easy to see: WaterFurnace geothermal systems are counted as one of the most efficient, energy-saving, eco-friendly heating and cooling solutions on the market today. Most geothermal units are a breeze to install - 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. If you're a Mt.
