Washington HVAC License Reciprocity and Out-of-State Transfer

Washington doesn't make it easy for out-of-state HVAC technicians. The state has one of the most restrictive reciprocity policies in the country for trade electricians — and since HVAC work in Washington is classified under the electrical licensing program, that restriction hits HVAC professionals directly.

The Reciprocity Situation

Washington maintains a reciprocal agreement with Oregon for the general journey-level electrician (EL01) classification only. If you hold an Oregon "J" license that was obtained by examination after completing an 8,000-hour apprenticeship and 576 classroom hours, you can apply for a Washington EL01 certificate without testing by submitting Form F500-148-000 along with the $114.60 application fee.

That's it. That's the entire list of reciprocal agreements.

Washington does not offer specialty electrical license reciprocity for the 06A or 06B HVAC classifications with any state. It doesn't matter if you've held a valid HVAC license in Texas for 20 years, or if you have a master electrician card from Florida. If you want the 06A or 06B specialty certificate that allows you to do HVAC electrical work in Washington, you're going through the full examination process.

The Out-of-State Application Process

Relocating HVAC technicians must submit an Out-of-State Electrical Examination Application (Form F626-009-000) to L&I with a nonrefundable $114.60 fee. The application requires:

Notarized experience documentation: You need signed, notarized affidavits from your previous employer(s) or your home state's licensing agency confirming you completed the required supervised field hours — 4,000 hours for the 06A certification or 2,000 hours for the 06B. L&I doesn't accept self-reported hours or generic letters of employment. Each affidavit must detail the type of work performed, the supervision ratio, and the time period.

Classroom training proof: You must submit documentation showing completion of at least 48 hours of classroom training covering the National Electrical Code and electrical theory (for 06A) or 24 hours (for 06B). The training must be from an L&I-approved provider or an equivalent program — out-of-state community college transcripts or trade school certificates usually qualify, but courses without a clear NEC curriculum component may be rejected.

Current credentials: Include copies of your existing state licenses, EPA 608 card, and any relevant certifications.

Taking the Washington Exam

Once L&I approves your application, you'll schedule the 06A or 06B specialty exam through PSI Services. The exam has two sections:

  1. NEC & Theory: Covers electrical theory and the National Electrical Code as adopted by Washington
  2. Washington Laws and Rules: Covers Chapter 19.28 RCW (electrical installation law) and Chapter 296-46B WAC (administrative rules)

Both sections are open-book. You can bring original, bound copies of the NEC, the Washington electrical statutes (RCW 19.28), and the administrative rules (WAC 296-46B) into the testing center. You need a 70% or better on each section to pass.

The Washington Laws and Rules section is where out-of-state technicians typically struggle. You can study for NEC questions with the same materials you used in your home state, but Washington's electrical statutes have specific provisions — administrator requirements, trainee supervision ratios, contractor registration rules — that don't exist in most other states' electrical codes.

Getting Your Experience Affidavits Before You Move

One of the biggest mistakes relocating technicians make is waiting until after they've moved to Washington to request experience documentation from their previous employer. Get your notarized affidavits before you leave.

Once you're in another state, getting a former employer to track down your hours, draft an affidavit, get it notarized, and mail it to you becomes significantly harder. If the employer has closed, you'll need to work directly with your previous state's licensing board to obtain verified records. Some states maintain centralized databases; others don't. Either way, this process takes weeks or months — time you'll spend unable to work legally in Washington.

If your previous employer refuses to sign or verify your hours, contact L&I's Electrical Licensing or Apprenticeship Compliance division directly. They have processes for handling uncooperative former employers, but they need to hear from you before you can proceed.

Setting Up Your Business After Certification

Passing the exam gets you the individual electrical credential. If you're planning to operate independently — not just work as an employee for an existing Washington contractor — you still need to set up a contractor registration with L&I. That means a corporate entity (LLC or equivalent), a $15,000 specialty contractor surety bond, $250,000 general liability insurance, a designated electrical administrator, and the $150.20 registration fee.

The Washington HVAC License Guide covers both paths — the individual licensing process for relocating technicians and the full business launch sequence — with a specific out-of-state transfer checklist that tracks every document you need to submit and in what order.
