Ground-Source Heating
A written, itemized quote in hand before any ground is broken, ground loop, indoor unit, and permit fees listed separately.
What We Arrange
We pass your property details to a local geothermal installer who assesses, quotes, and completes the full scope of work.
A site assessment confirms lot size and soil conditions before any ground loop is designed or quoted.
A structured diagnostic traces the fault from thermostat and controls through to compressor and ground loop.
Loop pressure, flow rate, and compressor output are each checked and recorded to support a repair-or-replace decision.
Annual checks of loop pressure, propylene glycol concentration, and coil condition catch failures before they cut off heat.
Shallow trenches laid across available yard area.
Drilled bores for lots with limited surface area.
Sized to your actual heating and cooling load.
Heat pump and air handler installed and integrated.
Connected to existing ducts or a radiant distribution system.
System verified at full capacity before handover.
Seattle City Light and federal credits flagged per project.
What Goes Wrong & How to Avoid It
Most problems come from skipped steps at the start, not from the technology itself.
A loop field sized from square footage alone, without a soil review, can fall short of the home’s actual heating load in cold snaps.
The installer runs a full heating and cooling load calculation and reviews soil conditions before the loop field dimensions are set.
A lump-sum quote buries permit fees inside a single number, so the real cost only appears after you have committed to the project.
The written quote separates the ground loop, the indoor unit, and permit fees so every cost is visible before any agreement is signed.
Trenching scope discussed only after equipment arrives means landscaping loss that was never agreed to or budgeted for.
The site assessment maps trench routes or bore locations before work starts, so yard impact is explained and accepted in writing first.
A general HVAC contractor unfamiliar with ground-loop systems may size the loop by rule of thumb rather than by soil conductivity and load data.
Enquiries go to installers who work specifically with ground-source systems, not contractors who treat geothermal as a side job.
Why Seattle Geothermal
We arrange the assessment, the quote, and the installer, so nothing falls through the gap between planning and digging.
You receive an itemized quote covering the ground loop, indoor unit, and permit fees before you commit to anything.
A local installer reviews your lot, soil conditions, and heating load before any system is sized or priced.
The same installer handles trenching or boring, the heat pump, distribution work, and startup commissioning end to end.
Enquiries go to contractors who work specifically with ground-source systems, not general HVAC firms taking on occasional geothermal jobs.
The installer flags Seattle City Light rebates and applicable federal tax credits as part of the quote process, not as an afterthought.
How It Works
01
Tell us the lot size, current heating setup, and site access so we can pass the right details to a local installer.
02
A local geothermal installer visits to review soil conditions, lot dimensions, and your home’s heating and cooling load.
03
The installer returns a written quote separating the ground loop, indoor unit, and permit fees before any work is scheduled.
Who We Help
Whether you are replacing a gas furnace or planning a new build, the process starts the same way: a site assessment and an itemized quote.
Older Seattle homes in neighborhoods like Capitol Hill or Ballard were typically built with gas furnaces that are now at or near end of life. We arrange a site assessment that accounts for the existing distribution layout and returns a quote that shows whether ductwork integration or a radiant swap makes more sense for the property.
Small commercial properties with rising energy costs and aging HVAC equipment are strong candidates for a ground-source system. We connect you with an installer who can assess the site, size the loop field to the building’s load, and identify any commercial rebates that apply.
New construction gives the most flexibility for loop field design, since trenching or bore locations can be planned before landscaping is in place. We arrange an installer to work alongside your build schedule and return a quote that separates every cost line before groundwork begins.
Property managers looking to reduce per-unit energy costs and meet sustainability targets can replace multiple aging systems with ground-source heat pumps. We arrange site assessments across the property and coordinate quotes that cover the full scope, from loop field design to indoor unit integration.
