Geothermal Retrofits More and more residents in Manhattan are realizing just how great geothermal systems are for retrofit or replacement applications. The benefits are plain to see: Geothermal systems are counted as one of the most dynamic, energy-conserving, 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's no combustion and therefore no need to vent exhaust gases. Geothermal technology is optimal for in-floor radiant heating, because hot water circulates throughout pipes below your floors to heat your rooms.
