Although installing a ground source heat pump is an expensive upfront cost, it significantly decreases the cost of heating and cooling for the oppucants. Gas utility bills can be up to 1/4 the cost of a typical month payment. Typically, a geothermal heat pump system costs about $2,500 per ton of capacity. Our housing typology would require a three-ton unit costing roughly $7,500. The cost of drilling would amount to about $15,000 but would be divided amougst the homeowners tapping into the geothermal source. There are several programs that help subsidize the intial costs. The U.S. government offers a one time tax credit of up to 30% of the total investment costs for a ground loop geothermal system, with a maximum credit of $2,000 for a single residence. Furthermore, several entities offer low-interest loans for up to $15,000 to residents.
