Licensed HVAC contracting with service rates of $85-$150/hour.
Starting an HVAC business in Hawaii requires proper licensing, EPA certification, and significant investment in specialized tools and equipment. Hawaii DCCA oversees HVAC licensing. AC and cooling systems dominate demand year-round. Startup costs range from $28,600 for a solo operator to $143,000+ for a fully equipped operation. Standard Hawaii business taxes apply. HVAC is a high-demand trade with strong earnings—contractors in Hawaii charge $85-$150/hour, with system installations generating $3,000-$15,000+ per job.
Any HVAC technician who maintains, services, or disposes of equipment containing refrigerants must hold EPA Section 608 certification. Violations carry fines up to $44,539 per day.
The EPA is phasing down HFC refrigerants under the AIM Act. Stay current on which refrigerants are available and train on new alternatives. This is both a challenge and business opportunity.
