InstaBidsHow much does a geothermal heat pump cost?
This survey has no geothermal heat pump installation-specific figure. The figure below covers all "Added or replaced built-in heating equipment" jobs, so read it as context, not as the price of geothermal heat pump installation alone.
Context: all "Added or replaced built-in heating equipment" jobs
$5,000 was the median homeowner survey figure for data years 2021-2023 in the United States. For all jobs in “Added or replaced built-in heating equipment”, households reported a typical range (middle half of 1,176 American Housing Survey data points, the United States, 2021-2023) of $2,500 to $8,000.

On InstaBids, describe the geothermal system you want so contractors write bids for that specific installation scope.
Cost of installing geothermal heat pump: can the loop be vertical or horizontal?
U.S. Department of Energy: “The loop can be buried either vertically or horizontally.”

Put the vertical or horizontal ground loop arrangement in your InstaBids scope so contractors address it in writing.
Cost to install a geothermal heat pump: what underground temperatures does it use?
U.S. Department of Energy: “Temperatures at about 30 feet below the surface remain relatively constant year-round—between about 50°F (10°C) and 59°F (15°C).”

On InstaBids, describe the ground collector and indoor equipment together in the geothermal job you post.
Cost to install geothermal heat pump: does the job include ductwork?
U.S. Department of Energy: “Conventional ductwork is generally used to distribute heated or cooled air from the geothermal heat pump throughout the building.”
Source: U.S. Department of Energy, read 2 November 2026.
Include the geothermal air distribution work in your InstaBids description for each contractor to address.
Geothermal heat pump install cost: which soil properties matter for the design?
U.S. Department of Energy: “For ground-coupled systems, important parameters include the thermal conductivity and temperature stability of the soil formation.”
Source: U.S. Department of Energy, read 2 November 2026.
On InstaBids, ask for the ground loop design assumptions in the written geothermal bids you receive.
Cost for geothermal heat pump: what does a groundwater design depend on?
U.S. Department of Energy: “The design of groundwater systems depends on several properties of the water source, including temperature, well flow rates, and water quality.”
Source: U.S. Department of Energy, read 2 November 2026.
Describe the proposed groundwater system on InstaBids so the written bids answer the same water source scope.
Geothermal heat pump costs: what service does the equipment need?
U.S. Department of Energy: “Having a trained technician service the heat pump annually is necessary to maintain peak performance.”
Source: U.S. Department of Energy, read 2 November 2026.
On InstaBids, include annual geothermal equipment service as a scope question for contractors bidding in writing.
Cost of geothermal heat pump: can it be added to an existing building?
U.S. Department of Energy: “Implemented as part of new construction or retroactively added for existing buildings”

Describe the existing building and geothermal retrofit work once on InstaBids for contractors to bid in writing.
What geothermal heat pump installation includes
Where a quote below names a city or county, it is that office's own rule, shown as one example; the permit office for your home may set different rules.
| What the source says | Where it comes from |
|---|---|
| U.S. Department of Energy: “A geothermal heat pump uses the earth as a heat source and sink (thermal storage), using a series of connected pipes buried in the ground near a building.” | U.S. Department of Energy, read 2 November 2026. |
| U.S. Department of Energy: “When ambient temperatures are colder than the ground, a geothermal heat pump removes heat from the collector’s fluids, concentrates it, and transfers it to the building.” | U.S. Department of Energy, read 2 November 2026. |
List the earth collector and geothermal heat pump together in the installation scope you describe on InstaBids.
Line items a written bid should list
- U.S. Department of Energy: “A proper assessment of the building's peak heating and cooling loads is critical to the design of a geothermal heat pump system.”
Source: U.S. Department of Energy, read 2 November 2026.
Use your InstaBids scope to ask each contractor for a written response about geothermal load assessment.
How to compare written bids like for like
Ask every contractor to bid in writing on the same line items listed above, then compare the written bids line by line.
U.S. Department of Energy: “Because ground heat exchangers represent a significant portion of the cost of these types of systems, it is important to size ground loops accurately.”
Source: U.S. Department of Energy, read 2 November 2026.
Compare how the written geothermal bids on InstaBids address the ground loop sizing in your description.
