Navigating contractor licensing in Hawaii requires precision. Hawaii requires a specialty contractor license (C-52 or C-40) to act as a contractor in these classifications under the Contractors License Board regulations. This guide details the steps to obtain your C-52 Ventilating and Air Conditioning Contractor or C-40 Refrigeration Contractor license.
Do You Need an HVAC Contractor License in Hawaii?

The state issues specific classifications for different scopes of work within the trade:
- C-52 Ventilating and Air Conditioning Contractor: The official C-52 classification is to fabricate, assemble, and install warm-air heating and air-cooling systems, complete ventilating systems, and complete air-conditioning systems, including specified related piping, controls, instrumentation, building automation, energy management, trenching, backfilling, patching, restoration, insulation, and heat pumps.
- C-40 Refrigeration Contractor: The C-40 classification is to assemble and install devices, machinery, units, insulation units, ducts, blowers, registers, humidity and thermostatic controls for air temperature below 50°F in refrigerators, refrigerator rooms, and insulated spaces, and construct walk-in refrigerator boxes.
Hawaii C-52/C-40 HVAC License Requirements
The Contractors License Board requires the qualifying individual (the Responsible Managing Employee - RME) to meet the following criteria:
- Age and Reputation: Must be at least 18 years of age and demonstrate a good reputation for honesty, truthfulness, financial integrity, and fair dealing.
- Experience: Demonstrate a minimum of four years of full-time, hands-on supervisory experience in the C-52 or C-40 trade classification within the ten years immediately preceding the application. This must be verified by certificates of experience submitted with the application.

The Hawaii C-52/C-40 HVAC Licensing Process
Obtaining a C-52 or C-40 HVAC license in Hawaii is a multi-step sequence:
- Submit the Application Packet: Complete and mail the "Application for Contractor's License" along with the non-refundable $50 application fee. For RME applications, you must include certificates of experience and a project list. For entity or sole-owner applications, you must include financial statements.
- Deadlines: Applications must be received by the Contractors License Board's filing deadline.
- Board Review and Approval: The Board reviews the application for completeness and experience verification. Sole-owner and entity applications are evaluated for financial solvency.
- Register and Pass the Exams: Once approved, candidates register with the state's exam administrator. You must pass both required exams within six months of approval.
- Exam Provider: Contractor examinations are administered by PSI Services, LLC (effective January 2023). Note that while some older DCCA forms may still reference Prometric, the dedicated examination scheduling page confirms PSI is the current testing administrator.
- Required Exams: Candidates must pass both the trade-specific exam (C-52 or C-40) and the Hawaii Contractor Business and Law exam.
- Submit Insurance Documentation: After passing the exams, you must submit proof of the required insurance coverage before the license is issued.
Insurance and Bonding Requirements
Hawaii specialty contractors must carry general liability insurance and workers' compensation insurance.
- General Liability Insurance: Contractors must maintain general liability insurance with the following minimum coverage limits:
- $100,000 for bodily injury to one person
- $300,000 for bodily injury per occurrence
- $50,000 for property damage per occurrence
- Workers' Compensation Insurance: A certificate of workers' compensation insurance is required unless an allowed exclusion applies.
EPA Section 608 Certification for HVAC Technicians
All technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must obtain EPA Section 608 Technician Certification. This is a mandatory federal requirement. There are four types of certification: Type I (small appliances), Type II (high-pressure), Type III (low-pressure), and Universal.
Renewing Your Hawaii License
Hawaii contractor licenses must be renewed biennially by September 30 of every even-numbered year. Unrenewed licenses are forfeited. No continuing education requirements for license renewals were identified in the reviewed Contractors License Board statutes and rules.
