How to Start an HVAC Business in Hawaii (2026)

Last updated: February 26, 2026

Starting an HVAC business in Hawaii requires the C-52 Ventilating and Air Conditioning Contractor license issued by the DCCA Professional and Vocational Licensing Division (PVL). The C-52 is a Class C specialty contractor license that authorizes fabrication, assembly, and installation of air conditioning, heating, ventilating systems, controls, and related thermal insulation. You need 4 years of supervisory HVAC experience, must pass both the C-52 trade exam and the Business & Law exam administered by PSI, and maintain minimum insurance coverage. Employees working under you do not need their own C-52 license – only the business owner or Responsible Managing Employee (RME) must hold it.

How to Start an HVAC Business in Hawaii (Step by Step)

Step 1: Form Your Business Entity and Get Your GET License

Register your HVAC business before applying for the contractor license. DCCA BREG will require your business entity information on the license application.

• LLC Formation: File Articles of Organization at hbe.ehawaii.gov. Fee: $50. Annual report: $15/year.
• EIN: Apply free at irs.gov.
• GET License: File Form BB-1 at Hawaii Tax Online. Fee: $20 one-time. HVAC services and installation are subject to GET at 4.5% combined (4.0% state + 0.5% county surcharge). Contractor services are GET-taxable.

Step 2: Obtain EPA Section 608 Certification

Any technician who purchases, handles, or recovers refrigerants must hold EPA Section 608 certification regardless of state licensing status. This is a federal requirement.

• Certification types: Type I (small appliances), Type II (high-pressure systems), Type III (low-pressure systems), or Universal (all types). Most HVAC techs pursue Universal certification.
• Cost: Approximately $20-$50 through EPA-approved testing centers.
• Where to test: ESCO, Mainstream Engineering, or other EPA-approved organizations administer the exam. Online options are available.

Step 3: Document Your Experience

The C-52 license requires proof of relevant supervisory experience:

• Experience requirement: 4 years of full-time supervisory experience as a journeyman, foreman, supervisor, or contractor in HVAC, within the previous 10 years. “Supervisory” means you directed others or had responsibility for quality of work, not simply performing hands-on work as a helper.
• Documentation: Three reference certificates from former employers, clients, or supervisors who can attest to your supervisory HVAC experience. Use DCCA’s official reference form.
• Pro tip: If you are applying as a business entity, you need a Responsible Managing Employee (RME) – a qualifying individual who holds or applies for the license on behalf of the business. The RME’s experience counts for the business.

Step 4: Apply for the C-52 License

Submit your application to the DCCA PVL Contractors License Board:

• Application fee: Approximately $50 (verify current fee on DCCA website)
• Submit to: DCCA PVL Contractors License Board, 335 Merchant Street, Honolulu, HI 96813. Applications and forms available at: cca.hawaii.gov/pvl/boards/contractor/application_publications
• What to include: Completed application, application fee, three reference certificates, proof of business entity registration (LLC documents), and any supporting experience documentation.
• After application approval: DCCA will authorize you to sit for the required exams and send instructions for scheduling through PSI.

Step 5: Pass Both Required Exams

Hawaii requires passing two exams administered by PSI Exams before a C-52 license is issued:

• C-52 Trade Exam: 80 questions, closed-book, 3 hours. Tests knowledge of HVAC systems, installation, code compliance, and safety. Passing score: 75%.
• Business & Law Exam: 80 questions, closed-book, 3 hours. Tests Hawaii contractor law, contract management, employment law, and business practices. Passing score: 75%.
• Exam fee: Approximately $75 per exam paid to PSI. Both exams may be taken on the same day at a PSI testing center.
• Study materials: DCCA provides a candidate information bulletin with recommended reference materials. The National HVAC Contractors Association and PSI both offer study guides.

Step 6: Obtain Required Insurance

Before your C-52 license is issued, you must demonstrate minimum insurance coverage:

• General Liability: $100,000 per person / $300,000 per occurrence
• Property Damage: $50,000
• Workers’ Compensation: Required upon hiring your first employee. Hawaii’s threshold is 1+ employee. Purchase from a Hawaii-licensed carrier. DLIR DCD: labor.hawaii.gov/dcd.
• Provide proof of insurance (certificate of insurance naming DCCA as certificate holder) with your license application.

Step 7: License Issuance and Renewal

• License fee: Approximately $415 if licensed between October 1 of an odd year and September 30 of an even year; approximately $215 if licensed in the other half of the biennial cycle (shorter period to next renewal). Fees reflect the biennial renewal structure.
• Renewal: Every 2 years by September 30 of even-numbered years (next: September 30, 2026). Renewal fee is the standard biennial amount.
• License board contact: DCCA PVL Contractors License Board, (808) 586-3000, cca.hawaii.gov/pvl/boards/contractor
