How to apply
To obtain an HVAC Contractor License in Washington, begin by registering with the Department of Labor & Industries online at https://lni.wa.gov. Complete the Application for HVAC Contractor License (Form HVA-001) and submit with proof of business registration, evidence of liability insurance coverage (minimum $300,000), and documentation of EPA refrigerant certification. You must pass the Washington State HVAC Competency Exam, which costs approximately $150 and covers heating systems, cooling systems, ventilation, electrical basics, and code compliance (Washington Revised Code § 18.106.070).
The exam is administered by third-party testing centers throughout Washington; schedule your exam through the L&I website. You must document four years of work experience in HVAC or a relevant apprenticeship completion from a registered apprenticeship program (WAC § 296-142-010). Alternatively, you may substitute related work experience, such as heating system installation or air conditioning service. Submit proof of workers' compensation insurance coverage (if you have employees) and proof of business liability insurance.
L&I will verify your experience and exam results, then issue your license upon approval. The application process typically takes 2-4 weeks from submission to issuance. Your license must be displayed at your place of business and kept current.
Federal Requirements
Federal requirements for HVAC contractors center on workplace safety, environmental compliance, and employee protections. All HVAC contractors employing workers must obtain an Employer Identification Number (EIN) from the Internal Revenue Service (26 U.S.C. § 1402) and maintain current federal tax identification. The Environmental Protection Agency (EPA) regulates refrigerant handling under the Clean Air Act (42 U.S.C. § 7671q), requiring technicians to be EPA-certified for servicing air conditioning and refrigeration systems containing ozone-depleting substances.
Occupational Safety and Health Administration (OSHA) standards (29 U.S.C. § 651 et seq.) apply to all HVAC work, including requirements for fall protection, electrical safety, and hazard communication. If your business employs workers, you must maintain workers' compensation insurance as required by federal employment law. The Americans with Disabilities Act (42 U.S.C. § 12101) requires that HVAC contractors provide accessible facilities and accommodate clients with disabilities during service calls.
Contractors should also comply with the Fair Labor Standards Act (29 U.S.C. § 201) regarding employee wages and hours. If handling refrigerants, you must comply with EPA regulations on recovery, recycling, and reclamation under 40 CFR Part 82. Additionally, businesses must maintain records of EPA-certified refrigerant handlers and document all refrigerant transactions.
Local & County Requirements
Spokane City imposes several local requirements for HVAC contractors beyond state licensing. All mechanical contractors must obtain a Trade License from Spokane City (Spokane Municipal Code § 17C.110), which costs $183 annually and must be renewed each year. Before beginning any HVAC work, you must pull a Mechanical Permit from Spokane City Community Development Services for each project (SMC § 17C.200). Permit fees are based on the estimated cost of work, typically ranging from $100-$500 depending on project scope.
Spokane requires all HVAC work to comply with the International Mechanical Code (IMC) and the Spokane Energy Code. Projects involving furnace replacement, ductwork installation, or commercial systems must pass inspection by Spokane Building Official inspectors at rough-in and final stages (SMC § 17C.250). Zoning compliance is mandatory; ensure your business location is in a zone permitting mechanical contracting services.
If your HVAC business includes refrigeration services, you may need additional permits from Spokane County Health District. Spokane County requires compliance with EPA refrigerant recovery standards and proper documentation of all refrigerant work (Spokane County Code § 17.08). For commercial HVAC systems serving food facilities, restaurants, or healthcare facilities, additional health department permits may apply. Bonding requirements may apply for certain commercial projects; verify with Spokane City before bidding. Contact Spokane City Community Development Services at (509) 625-6300 or visit their website for current permit requirements and fee schedules.
Total Cost Breakdown
The first-year cost to establish an HVAC contracting business in Spokane includes multiple required fees and expenses. The Washington State HVAC Contractor License application fee is $415-$550, plus the competency exam fee of approximately $150 (Washington Revised Code § 18.106.070). You must obtain liability insurance with minimum coverage of $300,000, which typically costs $800-$1,500 annually depending on business size and claims history.
Spokane City requires a Trade License costing $183 annually. Initial mechanical permits for your first project range from $100-$500 based on scope. EPA refrigerant certification training and exam cost approximately $200-$400 if not already certified. Workers' compensation insurance (required if you have employees) costs approximately $800-$2,000 in the first year depending on payroll and risk classification.
Business registration with Washington Secretary of State costs approximately $60-$120. A surety bond or contractors' license bond may be required for certain commercial projects, ranging from $300-$1,000 annually. First-year continuing education costs approximately $300-$500 for required 14 hours of approved coursework. Total estimated first-year startup costs range from $3,200-$6,000, including all licenses, permits, insurance, and education. Annual renewal costs (years 2+) are approximately $1,500-$2,500, covering license renewal, trade permit, insurance, and continuing education.
Licence Renewal
Washington HVAC Contractor Licenses must be renewed every two years (Washington Revised Code § 18.106.090). Your license will display an expiration date; renewal applications must be submitted at least 30 days before expiration to avoid lapse. The renewal fee is approximately $200-$250 (varies annually). To renew, log into your L&I account at lni.wa.gov and complete the renewal application, confirming continued compliance with liability insurance requirements (minimum $300,000 coverage) and EPA refrigerant certification.
Washington requires 14 continuing education hours for each two-year renewal cycle, with at least six hours in HVAC-specific topics and the remaining hours in business management, safety, or related technical areas (WAC § 296-142-020). Approved continuing education courses are available through community colleges, trade associations, and industry organizations. You must document all continuing education completion and maintain certificates for L&I verification.
Renewal can be completed entirely online through the L&I website; no in-person visit is required. If you miss the renewal deadline, your license automatically expires, and you cannot legally operate as an HVAC contractor until reactivation. Expired licenses can be reactivated with late fees (typically an additional $50-$100) and proof that you did not work unlicensed during the lapse period. Submit renewal applications at least 30 days before expiration to allow processing time and ensure continuous licensure without interruption.
Penalties for Operating Without a Licence
Operating as an HVAC contractor in Washington without a valid license is illegal and subject to significant penalties under Washington Revised Code § 18.106.130. The Department of Labor & Industries can assess civil penalties of up to $1,000 per violation, with each day of unlicensed operation constituting a separate violation. Criminal penalties under RCW § 18.106.130 include fines up to $5,000 and potential imprisonment up to 90 days for operating without a license.
L&I actively investigates unlicensed HVAC contractor operations through consumer complaints, inspector observations during construction projects, and permit applications. If discovered operating unlicensed, L&I issues a Cease and Desist order requiring immediate cessation of all HVAC work. The contractor must stop all operations, inform clients of unlicensed status, and may be required to complete inspections of previously installed work at the contractor's expense (WAC § 296-142-010). Failure to comply with a Cease and Desist order results in additional civil penalties and potential criminal prosecution.
Unlicensed operation creates liability exposure for customers, who cannot recover damages through the Construction Lien Law or HVAC license bond protections. Insurance companies may deny claims arising from unlicensed work, leaving both contractor and homeowner without coverage. Violated customer contracts may be unenforceable, and customers can file complaints with the Attorney General's Consumer Protection Division. If you perform unlicensed work and a customer suffers injury or property damage, you face personal liability without insurance coverage. Additionally, unlicensed contractors cannot pursue mechanics' liens or file claim disputes, severely limiting legal remedies for payment issues.

Frequently Asked Questions
Do I need a license to start an HVAC business in Spokane if I already have experience?
Yes, you must have a Washington State HVAC Contractor License regardless of experience level (Washington Revised Code § 18.106.040). However, Washington does recognize relevant work experience as qualification for the competency exam. You need four years of documented HVAC work experience or completion of a registered apprenticeship program to qualify for licensing. Even with decades of experience, you cannot legally perform HVAC work in Spokane without the active state license. The state license is non-negotiable and separate from any prior certifications or experience credentials. Operating without it exposes you to fines up to $5,000 and criminal penalties.
How long does the Washington HVAC license application process take from start to finish?
The complete process typically takes 6-12 weeks from initial application to receiving your active license. First, you must pass the Washington State HVAC Competency Exam, which you can schedule immediately after submitting your application; exam scheduling takes 1-2 weeks (Washington Revised Code § 18.106.070). The exam itself takes approximately 4 hours. After passing, you submit your exam results with your full application package to the Department of Labor & Industries. L&I processes the application in 2-4 weeks, verifying your experience documentation, insurance coverage, and EPA refrigerant certification. The entire timeline depends on how quickly you prepare documentation and schedule your exam. Spokane applicants should plan 8-10 weeks for a smooth process and allow 2-3 weeks of buffer time.
What happens if I perform HVAC work in Spokane before getting my license?
Performing unlicensed HVAC work in Spokane is illegal and carries serious consequences (Washington Revised Code § 18.106.130). You face civil penalties up to $1,000 per violation, with each day of work constituting a separate violation. Criminal penalties include fines up to $5,000 and potential jail time up to 90 days. The Department of Labor & Industries will issue a Cease and Desist order forcing you to stop all HVAC work immediately. Any work performed unlicensed cannot be legally billed or collected, and customers cannot recover damages through the Construction Lien Law. Your liability insurance will likely deny claims for unlicensed work, leaving you personally liable for any injuries or property damage. Additionally, you cannot obtain a license if L&I discovers you worked unlicensed, as this demonstrates willful violation.
Do I need separate local Spokane permits beyond my state HVAC license?
Yes, the state license is only one requirement (Washington Revised Code § 18.106.040). Spokane City requires a separate Trade License ($183 annually) and a Mechanical Permit for each individual project (Spokane Municipal Code § 17C.110, § 17C.200). Mechanical permit fees range from $100-$500 depending on project cost and complexity. You must pull permits before starting any HVAC work, and your work must pass inspections by Spokane Building Official inspectors. Additionally, if you serve commercial facilities like restaurants or healthcare buildings, Spokane County Health District permits may apply. Zoning compliance is also mandatory; confirm your business location is in a zone permitting mechanical contracting. The combination of state and local requirements is non-negotiable in Spokane.
Can I transfer my HVAC license from another state to Washington, or do I need a new license?
Washington does not have formal reciprocity agreements with other states for HVAC contractor licenses (Washington Revised Code § 18.106.040). If you hold an HVAC license from another state like California, Oregon, or Idaho, you cannot simply transfer it to Washington. However, out-of-state experience may count toward qualifying for the Washington competency exam. You must apply for a Washington HVAC Contractor License through the Department of Labor & Industries and pass the Washington State HVAC Competency Exam, which covers Washington-specific codes and regulations (WAC § 296-142-010). Out-of-state experience typically qualifies you to sit for the exam without additional apprenticeship requirements. The application process takes 2-4 weeks after exam passage. Contact L&I directly at (360) 902-9400 to discuss how your out-of-state credentials apply to Washington requirements.
