HVAC technician jobs in California: what to know
What an HVAC technician does
HVAC technicians install, maintain and repair heating, ventilation, air conditioning and refrigeration systems. In California that work is busy year-round: air conditioning in the Central Valley and Inland Empire summers, heat pumps as homes move away from gas, and commercial refrigeration for grocery stores and restaurants. You might work on homes, office buildings, hospitals or factory systems.
Types of HVAC jobs
- HVAC helper or apprentice: the usual starting point, assisting a technician on installs and service calls.
- Installer: puts in new equipment, ductwork and line sets.
- Service technician: diagnoses and repairs systems, usually driving a company van between calls.
- Refrigeration technician: walk-in coolers, freezers and commercial refrigeration.
- Building or controls technician: large commercial systems and building automation.
Licenses and certificates
- EPA Section 608: federal law requires this certification to buy or work with refrigerants. Most employers want it, and you can earn it by passing an exam.
- C-20 contractor license: businesses that do HVAC work in California need a C-20 license from the Contractors State License Board. As an employee, you work under your employer's license.
- Training from community colleges, trade schools or union apprenticeship programs helps you start at a higher level.
Skills employers look for
- Electrical basics: reading wiring diagrams and testing with a meter.
- Understanding how refrigerant cycles work and using gauges.
- Working in attics, on roofs and in tight spaces, including in the heat.
- A clean driving record for service roles.
- Explaining problems and prices clearly to customers.
How to get hired

- Apply for helper and apprentice roles, which train you on the job.
- Have your driver's license ready, and check whether the job includes a company vehicle.
- Ask how the company trains new techs and whether it pays for more certificates.
