HVAC Training Schools in Hawaii

Fortunately for those interested in finding work as an HVAC technician, available job opportunities are only expected to grow into the future. By illustration, the Bureau of Labor Statistics (BLS May 2024) reported that there were 396,870 HVAC technicians across the country, earning an average annual salary of $62,690. The BLS (2025) anticipated that the industry would grow 8 percent between 2024 and 2034, which is nearly three times as fast as the average for all occupations.

There’s evidence that Hawaii is predicted to need new technicians at a slower rate. Projections Central (2025)—a data organization partnered with the US Department of Labor—reported that there would be a 4.3 percent increase in HVAC positions across Hawaii between 2022 and 2032.

Of course, it’s impossible to pinpoint only one reason for growth in the field of HVAC. There are a number of driving factors; for one, as buildings continue to be erected in the state, demand will grow for skilled HVAC technicians who can install climate-control systems in the new construction projects.

Furthermore, climate-control systems must be maintained on a regular basis, and often need to be entirely replaced every 10 to 15 years; here, HVAC technicians must assist in this process. Finally, because the laws and regulations governing the HVAC industry are constantly in flux, technicians must stay abreast of these rules and help customers stay in compliance.

Generally, the easiest way to visualize the surge in demand for HVAC technicians is by performing an online search for jobs available in the area. For example, a search for HVAC positions in Hawaii on Monster (March 2026) brought up 219 results with companies such as Steve’s Plumbing & A/C, EPC Service Inc, Integrated Facility Services Hawaii, Inc, AlohaHP, Sunbelt Rentals, and many others. A similar search on Indeed (March 2026) yielded results with companies including Hawaii Unified, Air Conditioning Specialists Inc., Kokua Real Estate Services., and AirCare Hawaii, among others.

Before finding a job in the industry, aspiring HVAC technicians must first obtain some type of training, whether it is conducted formally or on the job. In many cases, the best training options are available through apprenticeships and degree or certificate programs, which combine classroom education with hands-on training to ensure graduates have the requisite skills and knowledge to succeed in the field.

For anyone interested in comprehensive training under the supervision of skilled professionals, an apprenticeship program through the Plumbers & Fitters UA Local Union 675 may be a worthwhile pursuit. The apprentice must complete 10,000 hours of on-the-job training and take courses in safety, soldering, brazing, welding, and various other skills. Apprentices are also paid for their work and receive other benefits, as well, including access to a pension, health insurance options, vacation time, and more.

As alluded to above, HVAC technicians must retain active EPA Section 608 Certification in order to perform work with refrigerants. This certification is split into four categories, including:

• Type 1 (small appliances)
• Type 2 (high-pressure appliances)
• Type 3 (low-pressure appliances)
• Type 4 (universal)

Furthermore, a number of skill-specific certifications are available to HVAC technicians, many of which can assist in a future job search. Currently, certifications are available through a number of organizations, including the Refrigerating Engineers and Technicians Association (e.g., entry-level Certified Assistant Refrigeration Operator); North American Technician Excellence (e.g., Industry Competency Exams or ICE); HVAC Excellence (e.g., Heating, Electrical, Air Conditioning Technology Plus); and others.

Finally, all HVAC technicians must comply with licensure requirements as set forth by the state government before performing any work. In Hawaii, in order to obtain a contractor license, a candidate must submit an application to the Board of Professional & Vocational Licensing with the Department of Commerce and Consumer Affairs, along with an application fee, and the following information:

• Proof of workers’ compensation insurance
• Proof of liability insurance in the amount of $100,000 for each person and $300,000 for each occurrence
• Proof of property damage insurance in the amount of $50,000 for each occurrence
• Location of the place of business
• An additional application submitted by a responsible managing employee, along with separate fees

Once the application is approved, the applicant must then complete two licensing examinations: one on business and law, and one on HVAC. Applicants should carefully choose the contractor classification for which they wish to apply. Class C-4 licenses cover those working with boilers, hot-water heating, and steam fitting, while C-40 is for refrigeration contractors and C-52 is for ventilating and air conditioning contractors.

The licensure process for HVAC workers in Hawaii may seem somewhat complex, but it is imperative that all professionals ensure they remain in compliance with the law.
