Hawaii does not publish broad reciprocity agreements — verify directly with DCCA

Hawaii's higher 75% passing score and mandatory Business & Law exam distinguish its licensing process. General liability insurance required ($100,000 per person / $300,000 per occurrence / $50,000 property damage minimum). Workers' compensation required if contractor has employees.
EPA 608 Certification — Required in All 50 States
Regardless of Hawaii's state licensing rules, any technician who purchases, handles, or works with regulated refrigerants must hold EPA Section 608 certification. This is a federal requirement under the Clean Air Act that no state law can waive. EPA 608 Universal (covering Type I, II, and III) is the most versatile credential for most HVAC roles.
