Bringing your license from another state
Washington DOES license HVAC — never read 'no HVAC board' as no license: HVAC/refrigeration lives inside the ELECTRICAL program as specialty certificates (06A HVAC/Refrigeration System at 4,000 hours; 06B at 2,000). The transfer answer is essentially NO for these specialties: the out-of-state credit rules are written for the GENERAL journey-level electrician (8,000 supervised hours, exam-earned, or 16,000 documented hours), nothing equivalent exists for 06A/06B, and master-level credit is barred outright — 'no credit may be applied from out-of-state.' Plan on Washington's own hour-and-exam route.
Can you work while it is pending?
Partially established: the TRAINEE certificate is the lawful work-while-qualifying lane — supervised, hours logged by affidavit. No provision covers work while a specialty certification application is pending.
The exam and the hours
Specialty certification is exam-gated after the hour thresholds — and QUALIFYING EMPLOYMENT is a rule of its own: hours only count worked for an employer with at least one properly certified journey-level or specialty electrician on staff. Uncertified-shop hours are dead hours. Your personal floor is EPA 608.
How apprenticing works here
The trainee lane starts at 16 with basic trainee classes, banking hours by affidavit toward the 1,000/2,000/4,000-hour specialty thresholds under certified supervision.
The local picture
The L&I program governs statewide.
If you want to contract for yourself
The contracting business carries its own L&I electrical-contractor registration; the tech carries the specialty certificate. Two separate obligations that never substitute for each other.
