Quick Answer
The costs involved in installing a geothermal heat pump system range from $10 to $30 per square foot, depending on the type of system and installation complexity, with a typical total cost between $30,000 to $90,000 for an average-sized home.
Initial System Costs
Initial system costs include the cost of the heat pump unit, which ranges from $5,000 to $15,000, the cost of the geothermal field, such as a pond loop, which can range from $10,000 to $30,000, and the cost of installation, which can range from $5,000 to $20,000. The total initial cost can range from $20,000 to $65,000.
Ongoing Savings and Maintenance Costs
Homeowners can expect to save $1,000 to $2,000 per year on their energy bills with a geothermal heat pump system. Regular maintenance costs are relatively low, around $500 to $1,000 per year, and the system’s lifespan can be 25 years or more.
Financing Options and Incentives
Homeowners can take advantage of various financing options, including loans and rebates, to help offset the initial cost of a geothermal heat pump system. In the United States, the IRS offers a tax credit of 26% of the total system cost, which can be worth up to $14,000. Additionally, many utility companies and local governments offer rebates and incentives for installing energy-efficient systems like geothermal heat pumps.
