California Requirements

To work as an HVAC professional in California, it’s necessary to obtain a C-20 Warm Air Heating, Ventilating, and Air Conditioning Contractor License.

Contractors State License Board logo

This license can be acquired through two avenues: completing formal education and on-the-job training, or accumulating four years of journeyman work experience.

While getting the required license is crucial, HVAC technicians have the opportunity to enhance their career prospects and expand their knowledge by pursuing additional certifications.

Two popular certifications in the field are:

  • The EPA license is required for anyone who handles refrigerants and demonstrates their understanding of safe handling and disposal practices.
  • NATE certification is nationally recognized and validates a technician’s technical expertise and knowledge of HVAC systems.

The course listed above is geared towards prepping you for these certifications.


If you’re on a mission to become a skilled HVAC technician, one of the best paths toward that goal involves enrolling in an apprenticeship program.

In California, these programs are usually available through industry associations or trade unions.

Some of the reputable associations in the region include:

When you opt for an apprenticeship program, you’ll have the opportunity to work alongside experienced HVAC technicians, who will guide you through every step of the way while receiving a stipend.

The length of the apprenticeship may differ based on the program, but it usually lasts between three and five years.

State Licensure

In California, HVAC contractors and technicians who work on systems worth more than $500 must acquire state licensure. The California Contractors State License Board (CSLB) is the governing body responsible for regulating the industry and ensuring compliance.

To get a license, applicants must meet certain requirements, which include:

  • Obtaining a minimum of four years of experience working in HVAC
  • Apply for Original Contractors License C-20 specialty
  • Passing a state exam
  • Get EPA Section 608 Certification (included in the course above)
  • Purchasing a bond of $15,000

Keep in mind that the licensure requirements can differ depending on the area of specialization within the HVAC industry. Therefore, conducting thorough research to understand the criteria applicable to your specific field is vital.

Acquiring a state license not only fulfills legal obligations but also instills confidence in customers, assuring them of your qualifications and ability to deliver top-quality HVAC services.


If you intend to become an HVAC professional in California, you will need to pass two exams in order to obtain licensure.

The HVAC exam
