HVAC TECHNICIAN
Installs, maintains, repairs heating, ventilation, air conditioning, and refrigeration. Year-round demand, climate-change tailwind. California is not a right-to-work state — union density is higher than average and prevailing wage rules cover most public projects.
The License.
Most states issue a journeyman license (allows you to work under a licensed contractor) and a separate master or contractor license (allows you to pull permits and run your own business). The journeyman license typically requires completing your apprenticeship and passing a written exam; the master/contractor license requires additional field hours — usually 2 years as a journeyman — and a separate exam.
Requirements in California: confirm current hour and exam requirements directly with California Contractors State License Board (CSLB). Rules update frequently and our data reflects published standards as of early 2025.

Source: BLS OEWS May 2025. These are median wages across all workers (union and non-union). Year 1 apprentice: $34,000–$48,000/yr. Journeyman top of scale: $56,000–$96,000/yr.
California is NOT a right-to-work state. Union scale in California's major metros typically runs 20–40% above the national median. Prevailing wage laws apply to most public-sector projects.
The Path.
California does NOT use the federal RAPIDS system. The state's Division of Apprenticeship Standards (DAS) administers all registered apprenticeship programs independently. A RAPIDS-registered apprenticeship from another state may not transfer. Find California programs at dir.ca.gov/das.

The Exam.
Licensing exams for hvac technician work typically cover the applicable mechanical code (IMC or state-specific), plumbing code (IPC or UPC depending on the state), and material standards. California may adopt different code editions than adjacent states. Confirm the specific code edition before purchasing prep materials. Prevailing wage requirements in California apply to most public-sector projects, which ties exam and licensure to wage scale compliance for contractors.
Be honest about pass rates. Many licensing boards do not publish them. When they do, first-time pass rates for journeyman exams in the trades typically run 50–75%. Preparation time varies — most serious candidates spend 60–120 hours on exam prep. Use code books from the correct edition, not what's currently in print.
What recruiters won't tell you.
- 01EPA 608 is required by federal law to handle refrigerant. Get it first.
- 02Residential service is commission/spiff-heavy — pay claims often inflated by recruiters.
- 03Some 'HVAC' trade school programs cost $15K+ for what a community college does for $3K.
- 04Lincoln Tech, UTI, and Penn Foster HVAC programs have had repeated regulatory scrutiny — check outcomes before enrolling.
- 05California has its own apprenticeship agency (DAS) and does NOT use the federal RAPIDS system. A RAPIDS-registered apprenticeship from another state may not transfer directly.
- 06California CSLB licensing is required for any job over $500 in labor and materials. Working unlicensed is a misdemeanor and can result in fines up to $15,000.
