Geothermal Heat Pump Maintenance Questions

Most manufacturers recommend one full maintenance visit per year. A system that heats and cools year-round in Seattle’s climate benefits from a visit before the heating season starts, so any loop or heat exchanger issues are resolved before peak demand.

Antifreeze concentration can fall outside the rated range, leaving the loop vulnerable to freezing. Heat exchanger deposits accumulate and reduce heat transfer, raising operating costs. Catching these issues late often means a repair call rather than a routine service visit.

Federal tax credits apply to installation, not ongoing maintenance. Seattle City Light rebate terms vary by program year. A local geothermal contractor can confirm current rebate conditions and whether documented maintenance records support any ongoing program requirements.

Yes. If your system includes a desuperheater for water heating, the contractor checks its connections and flow as part of the itemized visit. Any wear is flagged in writing alongside the loop and heat exchanger findings.

A full visit covering loop pressure, flow verification, antifreeze testing, filter replacement, and heat exchanger cleaning typically takes two to three hours. The contractor confirms rated capacity before leaving, so the visit length depends on what the checks reveal.

Yes. We connect you with a local geothermal contractor who can service any ground-source system regardless of who installed it. The contractor will review available installation records and document a baseline reading set at the first visit.
