An inspection starts with the ground loop: the contractor reads static and operating pressure, checks flow rate through the circulation pump, and tests antifreeze concentration. Pacific Northwest soil moisture can affect loop grout integrity over time, so a pressure drop that looks minor may indicate a slow leak. These readings are recorded so future visits have a baseline for comparison.
The compressor and heat exchanger are tested next. Output is measured against the unit’s rated capacity, and the reversing valve is cycled to confirm it switches correctly between heating and cooling modes. Control board function and thermostat calibration are reviewed last, since a miscalibrated thermostat can mimic a capacity problem and lead to unnecessary component replacement.
Seattle’s older residential properties often have ground loops and components installed a decade or more ago with no documented service history. An inspection produces a written condition report covering each checked item, which gives you a factual basis for a repair-versus-replacement decision rather than a guess. The findings are walked through with you before any further work is scheduled.
Why Choose Us
Why choose us for a geothermal system inspection in Seattle?
We schedule a geothermal visit that documents every finding and walks you through the results before any work is proposed.
Written Report on Every Visit
Every inspection produces a written condition report covering each checked component, so findings are documented, not verbal.
Repair-or-Replace Clarity
The report is structured to support a repair-versus-replacement decision, giving you a factual starting point rather than a guess.
On-Site Assessments
Every visit brings hands-on experience with Seattle’s older residential ground loops.
No Pressure Beyond the Findings
Nothing beyond the inspection is scheduled until you have reviewed the written report and decided on next steps yourself.
Itemized Quote Before Any Work
If follow-on work is needed, the quote separates the ground loop, indoor unit, and permit fees so the total cost is clear upfront.
Questions about geothermal system inspections in Seattle
When does a geothermal system actually need an inspection?
Before buying or selling a property with an existing ground-source heat pump is the most common trigger. It also makes sense when heating or cooling output has dropped, energy bills have risen without explanation, or a property manager needs a documented baseline for maintenance planning.
What does the inspection actually cover?
The contractor checks loop field pressure and antifreeze concentration, measures flow rates through the heat exchanger, records indoor unit performance data, and confirms desuperheater function if water heating is part of the system. Each component is reported separately.
What happens if I delay getting an inspection?
Loop pressure loss and heat exchanger fouling both worsen gradually. Catching either fault early is a maintenance task; missing it until the system can no longer meet load turns it into an emergency repair that costs significantly more and may require loop field work.
Does the inspection report tell me what repairs are needed?
Yes. The written report documents each component’s measured result against its original specification and includes recommended follow-up steps. You will know which parts are within spec and which are not, with clear guidance on what to address first.
Are geothermal inspections regulated or permit-required in Seattle?
The inspection itself does not require a permit. Any repair or modification work that follows may require a mechanical permit under Seattle’s building code. Permit requirements are confirmed before any follow-up work is scheduled.
Can the same contractor carry out repairs found during the inspection?
Yes. If the inspection identifies faults, a separate written quote covers any repair or remediation work. That quote will itemize parts, labor, and any permit fees before work begins.
Tell us the property, the system age, and what you have noticed. We schedule an inspection and deliver a written report before any further work is discussed.
