You may look at the price tag for a geothermal heating system and dismiss it out of hand: Systems can cost $10,000 to $25,000 and up. But with federal tax credits for geothermal heat pumps until 2016, you can cut your purchase and installation costs by 30% and your energy bills in half.
Plus, you likely won’t need to replace your system as often as you would a typical heat pump, gas furnace, or air conditioner; geothermal systems can last a lifetime and need fewer repairs than other types of heating and cooling systems. They’re underground, sheltered from weather extremes.
