Are geothermal systems difficult to install?
Most units are easy to install, especially when they are replacing another forced-air system. This is known as a retrofit. Geothermal systems can be installed in areas unsuitable for fossil fuel furnaces because there is no combustion and thus no need to vent exhaust fumes. Ductwork must be installed in homes without an existing air distribution system. Geothermal systems can also be integrated with hydronic heat systems. Your dealer or installer can assess the cost of installing ductwork or plumbing.
