Contractors that do both HVAC and electrical in Seattle, WA
A ranked shortlist of firms licensed for both HVAC and electrical for someone hiring or vetting in Seattle. One company doing the combined work, not two separate specialists. Ranked on an active L&I class in each trade and job-relevant Seattle permits, not reviews, ads, or a workmanship guarantee.
Seattle permit records through 2026-08-27, verified against the Washington State Department of Labor & Industries licensing records, snapshot dated 2026-08-16. Ranking reflects license standing and permit history, not a workmanship guarantee. This week's Seattle permit activity.
Which contractor that does both HVAC and electrical has pulled the most HVAC and electrical permits in Seattle?
Go Green Heating AC & Elec LLC has pulled the most HVAC and electrical permits in Seattle of any firm holding the matching L&I class: 2,257 permits, most recently in 2026. It has held L&I license GOGREGH752DL for 1 year.
That count includes only permits whose type matches HVAC and electrical work in Seattle's own records, and only firms that hold the matching L&I class as a primary or tied specialty, so a firm with a larger pile of unrelated permits does not rank here. Permits are counted per license number, and a firm holding several licenses is counted on its busiest one. Seattle records run through 2026-08-27.

How this ranking works
Organic results require an active L&I license, the correct class for the trade as the firm's primary or tied fit (a mechanical company that also holds an electrical license does not lead the electrician list), and at least one job-relevant building permit in this city's records. They are ranked by the number of relevant permits, then by how recently the firm worked, then by how long the firm has been licensed. This reflects license standing and real permit history - it is not a workmanship guarantee. L&I does not publish a disciplinary file, so a clean record is not part of this ranking. Promoted entries, when present, are paid placements and are not scored by these rules.
Confidence: high. The permit type and the license class both match this trade.
