Geothermal heat pump installation
Most of the job happens underground. The loop is designed once and lasts far longer than the machine inside.

The short version
Geothermal heat pump installation has two parts: an indoor heat pump and a ground loop buried in your yard or drilled under it. DOE estimates the inside components last about 25 years and the ground loop more than 50, so the loop design matters most.
The loop types, and what decides between them
Your lot and soil usually choose for you.
Pipe in trenches. Needs open land.
Pipe in drilled boreholes. Fits small lots, needs a drilling rig and often a well-drilling permit.
Coils sunk in a pond of enough size and depth.
Use well water directly. Depend on water quality, supply and local rules on discharge.
What a correct geothermal installation includes
Ask for each one.
The loop length follows from the load, so a guess here is buried for decades.
Soil type and moisture change how much loop you need.
Leaks are cheap to fix before the trench is closed.
Rules vary by state and county.
Future owners need to know where it is.
Red flags in an installation quote
Any one of these is a reason to ask more questions or get another quote.
No room-by-room load calculation means the size is a guess.
Most jurisdictions require a mechanical permit and inspection for new equipment. Ask who pulls it.
A quote that says "16 SEER system" without model numbers cannot be checked against the AHRI directory.
Too short a loop cannot be extended cheaply later.
Ask for the reading.
What drives the price of geothermal installation
HyreHVAC does not publish a price for geothermal installation. We do not yet hold enough sourced, dated quotes to give a figure we can stand behind.
The loop is most of it: type, length, drilling depth and rock, plus the indoor unit and duct or electrical work.
Our HVAC cost guides explain each driver, and the heat pump savings calculator lets you work through your own numbers.
A note on incentives
Geothermal incentives change often. Check current HVAC incentives and your utility before you budget. See also heat pump versus gas furnace for running-cost framing.
What happens after you ask
You fill in the HVAC options form with the job and your zip code. HyreHVAC is a publisher, not a contractor, and contractor matching is still being built. Until it is, treat the form as an inquiry. Keep getting your own written quotes and check each installer’s licence with your state board.

Tell us about the work
Three short steps: the job, your home, and how to reach you. Nothing goes to an HVAC company unless you agree.
A person reads it and replies, free and with no obligation. Matching is not live yet, so this is not a quote. If you smell gas or a CO alarm sounds, leave the house and call 911 or your gas utility first.

Questions
How long does a geothermal system last?
Do I have enough land?
Can I reuse the loop when the heat pump wears out?
Will the yard be torn up?

Primary-source research, data analysis and fact checking
We are a research desk, not a sales floor. We read the federal microdata file, the statute or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify.
The counts below are generated from the published pages themselves, last counted November 12, 2026, and they are what we have actually published rather than what we intend to.
- 18
- studies published
- 15
- federal sources read and cited
- 15
- studies published with their full dataset as CSV
- 51
- jurisdictions reproduced against EIA’s own tables
How this desk works
- Primary sources only. Federal data comes from the agency that collects it, in the file that agency publishes. We do not cite an article that cites a source; we download the source and compute the figure ourselves.
- We validate against the agency before we publish. First, we use each federal microdata file to reproduce the agency’s own published tables. Our cooling research reproduces EIA’s state estimates and standard errors for all 51 jurisdictions. That check caught a variance formula that was off by a factor of four.
- Every estimate carries its uncertainty. These are survey figures, not counts. Standard errors are computed from the replicate weights the federal file supplies and printed beside the estimate. An estimate too imprecise to publish is reported as such rather than printed.
- Nothing is typed by hand. Prose, tables and charts all read from one dataset built by script, so a number in a sentence and the same number in the table below it cannot disagree.
- We publish the data, not just the conclusion. 15 of our 18 studies offer the full computed table as a CSV download on the page, so you can check the analysis or disagree with it. A study without a row-level dataset gets no download link and claims none in its structured data.
- We correct in public. Where we have published a figure wrongly we fix the figure, rewrite any analysis that rested on it rather than patching the number underneath it, and leave a dated correction note on the page.
- We do not install or sell HVAC equipment, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Data as of October 26, 2026. Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
Sources & retrieval dates
HyreHVAC is a publisher. We do not install, repair or inspect HVAC equipment and hold no contractor licence. Nothing here replaces an on-site diagnosis by a licensed contractor. Sources are cited with the date they were checked.
