Geothermal Heating Installation Costs

Indoor Cost Guides      Air-Conditioning & Heating (HVAC)      Geothermal Heating Installation Costs

Geothermal heat pumps are becoming popular because they can be integrated into a number of existing HVAC systems, including forced air and radiant heat. This type of heating installation will depend on the size of the system that you need and the installation cost, depending on the project difficulty.

Geothermal heating is more efficient than a traditional gas or electric heating or cooling system. It utilizes a ground heat exchanger, which adds a premium cost to just about every model. You will also need to calculate about 35% of your materials for waste to ensure that you don’t run out on installation day.

Geothermal heating installation: by type of installation and pump.

Item Equipment Cost Horizontal Loop Total Vertical Loop Total
Split water-to-air pump $3,850-$7,500 $14,000-$22,000 $17,500-$26,000
Packaged water-to-air heating system $3,300-$7,000 $12,000-$20,000 $15,750-$24,000
Package water-to-water system $4,000-$7,000 $16,200-$25,000 $20,000-$30,000


Other considerations and costs

  • There may be tax breaks available for installing a higher-quality and more eco-friendly heating and cooling solution like geothermal heating. Be sure to keep all of your paperwork and receipts.
  • A geothermal professional should come to your home and perform a full assessment to ensure that all areas are sealed when they should be and accessible when you need them open.
  • Modern systems come with a ground heat exchanger, which either has an open-loop or closed-loop system.
  • Prices quoted here do not cover a lot of site prep or special circumstances, where you could spend thousands more on the installation process. Make sure that you get a full in-home estimate so that you know exactly what you are paying for.
  • Permits aren’t usually required for projects like this, but if extensive work is being done, you should consult with someone regarding whether or not you need them and how much they will cost.
  • Replacing or repairing ductwork to go with the new geothermal heating system can also add to the bill substantially. If you are investing in a new system, though, you want to make sure that it works as efficiently as possible.

DIY considerations

  • Shop around for geothermal heating units at local home improvement stores and online for cheaper options than you might find by letting an installer bring the parts along.
  • Geothermal heating installation is never a DIY job. This requires extensive knowledge of HVAC systems and heat pumps, and should only be done by a certified, licensed contractor.
