Putting in geothermal heating takes a week of digging up your lawn, but its benefits could make it your next big home improvement project.

Experts say installing geothermal heating can cost $10,000 to $20,000 for an average three-to-four bedroom home. But those who have had the heating and cooling system for years say it pays for itself in less than 10 years.

Mary Roberts is the executive director at the David Martin House in Buffalo. The house installed 35 350-foot-deep wells under its Summit Lawn that provide geothermal heating and cooling to the complex.

She says she feels no difference from the old system they used, and the new system is nearly 50% more efficient.
