Mandatory Business Licenses (Contractor Level)
If you plan to operate your own HVAC contracting business, you must register as a contractor with the Washington State Department of Labor & Industries.
Contractor Registration (Specialty Contractor):
Business Structure: Choose your business structure (sole proprietorship, partnership, LLC, corporation) and register it with the Washington Secretary of State if applicable (corporations/LLCs will get a Unified Business Identifier - UBI number). Sole proprietors and partnerships will get a UBI through the L&I registration process.
Surety Bond:
Specialty Contractors: Required to have a $6,000 surety bond. (Note: This increases to $15,000 on July 1, 2024).
Alternatively, you can set up a dedicated assigned savings account at a Washington bank instead of purchasing a bond.
Insurance:
General Liability Insurance: Minimum coverage of $200,000 public liability and $50,000 property damage, OR a $250,000 combined single limit.
Workers' Compensation Insurance: Mandatory if you have employees. You must have an industrial insurance account number.
Application: Complete and submit the "Application for Contractor Registration."
Age: The applicant must be 18 years or older to register as a construction contractor.
Fee: $132.60 application fee.
Renewal: Every two years.
Local City Licenses: Many cities and counties in Washington, including Seattle, Spokane, Kennewick, Pullman, and Yakima, require additional local licenses for HVAC and refrigeration professionals. These often include their own specific exams and requirements for gas installation, heating journeyman, or refrigeration mechanic licenses. It is critical to check with the specific municipality where you plan to work.
Example (Seattle): Requires a "Refrigeration and Air Conditioning Contractor" license, which mandates that the contractor either holds a Master Refrigeration Mechanic license or employs at least one Master Refrigeration Mechanic. Seattle also has separate gas piping licenses.
Example (Kennewick): Requires a "Gas Installation License" with a written test.
Federal Tax ID (EIN) Number: Required for almost all types of businesses.
State Tax ID Number: Issued by the Washington State Department of Revenue.
Obtain Electrical Trainee Certificate: Start by registering as an electrical trainee and begin accumulating supervised work hours under a certified electrician. Fulfill the annual continuing education requirements for the trainee certificate.
Gain Experience and Education: Work the required hours (e.g., 4,000 for 06A, 2,000 for 06B) and complete the necessary classroom instruction for your chosen Specialty Electrician HVAC/R license.

Receive Licenses/Registrations: Upon successful completion of all state and local requirements, you will receive your Specialty Electrician license, Contractor Registration, and any necessary local city licenses.
Fragmented Licensing: Washington's system is highly fragmented. You need both state-level electrical specialty licenses for the individual performing the work AND a state-level contractor registration for the business, AND often various city-specific licenses/certifications for gas and mechanical work.
Continuing Education: All electrical licenses (trainee, specialty, journeyman, master) require ongoing continuing education hours for renewal.
Reciprocity: Washington has limited reciprocity for electricians with some states (e.g., Oregon, Idaho) for certain license types, but it's not universal for HVAC-specific electrical specialties.
