cost of converting to geothermal
Letâs not sugarcoat itâinstalling a geothermal system is expensive. It costs $10,000 to $30,000 depending on your soil conditions, plot size, system configuration, site accessibility and the amount of digging and drilling required. For a typical 2,000-sq.-ft. home, a geothermal retrofit ranges from $10,000 to $20,000.
