Geothermal Heat Pump Cost: The Pros, The Cons, The Tax Breaks
Cost of Geothermal Installation | Tax Breaks | Free Estimates from Local Pros
Despite rising popularity, sticker shock is still a frequent reaction upon seeing the cost of geothermal installation. Geothermal heat pumps are usually somewhere between $11,000 and $30,000. Most of that stems from the installation cost.
Prices can range wildly. Contractors and homeowners in different areas with different needs have reported vastly different prices. Some homeowners have reported the cost of geothermal installation ran them about $7,000 for a 2,000 square foot home. Others have said the price toppled $30,000 for the same size home. A family quoted in a story by National Public Radio reported that they spent $20,000 for installation in a 1,900 square foot home, but were only capable of keeping it that low because they rented their own backhoe and dug a trench. But the price was worth it, they said, because it dropped their energy bills from $600 with an oil furnace to $100 per month with geothermal heat.
Generally, for each ton of capacity, air source heat pumps are about $3,000 less to install than geothermal heat pumps.
Why is the cost of geothermal installation so steep and subject to such extreme fluctuation? Because, unlike traditional heating and cooling systems, the infrastructure that goes into geothermal heat pumps is far more intensive. Trenches must be dug to lay the piping from your house to an area beneath the surface of the earth. Additional geothermal heat pump costs can include the installation of specialized geothermal piping, desuperheaters (auxiliary heat exchangers that lessen the need for underground piping), and boring holes for the geothermal system. You may need many adjustments made to the home to outfit it for a geothermal heat pump.
How much it will cost you is a question that can only be answered with an in-home appointment from a contractor. The Better Business Bureau recommends that you seek a minimum of three estimates from area professionals to ensure you strike a balance between quality work at a reasonable price.

Many homeowners say it's a price worth paying. Geothermal heat pumps are at least 45 percent more efficient than traditional fuel combustion systems like electric, oil, and gas furnaces. Meanwhile, you can claim a 30% tax credit. With that kind of savings, those high initial geothermal heat pump prices often pay for themselves in a few years.
Geothermal Heating System Cost
Geothermal heating costs are usually determined by ton of capacity. Heating capacity is the amount of energy used to heat one gram of water 1°C. This may seem like an abstract concept; however it provides a standard to which you can compare your needs to available systems. An average home needs three tons of heating capacity, and the average cost of a geothermal system is at least $2,500 per ton of capacity.
Geothermal Heat Pump Cost and Tax Credit Benefits
For further cost reduction, new tax rebates are available that repay 30% of your renovation costs up to $2000 for newly installed geothermal equipment. Visit EnergyStar for more information. Further savings can come from deals with local electric companies. Some electric companies offer special rates to customers with geothermal heating systems, as the reduced usage allows the electric companies to sell more of their electricity to others. Other electric companies pay for geothermal system installation, and the customers pay to lease the system, which is still cheaper than electrical usage.
The Advantages Of Geothermal Heating
There are many pros when it comes to upgrading to a geothermal heating system, and they usually outweigh the cons:
- Low Operating Cost – geothermal heat pump cost tends to be lower than conventional heating systems by anywhere from $400 to $1,400 per year. Despite spending a little more initially, geothermal heating ends up paying back in around five years.
- Environmental Impact – geothermal heat pumps cost less and they have less of an effect on the environment. Open loop systems reduce emissions by up to 40% while making little environmental impact otherwise.
- Reliability – geothermal systems can last anywhere from 20 to 50 years. When located away from harsh elements, the heat pumps themselves are known to last for much more than 20 years.
- Easy Retrofitting – geothermal heat pumps and geothermal systems are easy to integrate with older systems without the hassle of complicated duckwork or replacement of parts.
The Disadvantages of Geothermal Heating
A geothermal system's biggest disadvantage is its initial cost. Installation of a heat pump and interior ductwork can nearly be double that of traditional furnace systems. These cost disadvantages can easily be offset, however, with savings on utility bills and possible rebates from your local electric company. Look into efficiency discounts offered in your region and you may be able to drastically reduce your initial installation and geothermal heating costs.
Geothermal Heating Systems and Spatial Considerations
Beside the disadvantages related to the cost of geothermal installation, geothermal systems can also require a large amount of space. A geothermal heat pump is usually installed in the home's interior, which may or may not be an issue depending on the layout of the house. However, the trenches or geothermal bore holes for the piping can require several hundred feet of open space, and wells for geothermal loop systems can also require special considerations. Finding a contractor with a superior level of experience when it comes to geothermal heat pump installation is crucial when thinking about where to install your unit.
Geothermal Heating Permits
You may also need permits to dig trenches and wells, so check with your local public utility company before starting any project. There are a variety of geothermal heating systems though, so choosing the right system will reduce these disadvantages. Before making a decision consider the many advantages of geothermal heating.
