UA Local 250 Apprenticeship

What do HVAC techs earn in California?
California HVAC technicians average about $73,900 per year, with entry-level graduates typically starting between $25 and $36 per hour and experienced techs in major metros pushing well beyond that. Licensing status moves the number more than anything else, which is why the California licensing guide should be read alongside this list.
California HVAC schools: frequently asked questions
Do you need a license to work as an HVAC technician in California?
Not as an employee. California licenses contractors, not technicians: the CSLB C-20 Warm-Air Heating, Ventilating and Air-Conditioning license is required to contract jobs of $1,000 or more, and it takes four years of journey-level experience to qualify. School plus employed field years is the standard route to that experience.
How much does HVAC school cost in California?
At community colleges, remarkably little: $46 per unit means Fresno City's 28-unit certificate runs about $1,288, and San Francisco residents attend CCSF tuition-free under Free City. Private schools like Brownson charge substantially more for focus and speed. The union apprenticeship costs nothing and pays you.
Which is the best HVAC school in Los Angeles?
LATTC is the legacy answer, training LA's trades workforce since 1925 with the deepest employer recognition in Southern California, at community college prices. The honest caveat is enrollment bureaucracy and full lab sections, so apply early. Graduates feed both open-shop employers and the Local 250 apprenticeship.
Is the California union apprenticeship worth it?
If you want commercial and industrial work, yes, strongly. Local 250's five paid years produce refrigeration fitters earning at scales classroom routes rarely reach. If you want residential service, the open-shop route through a college certificate is faster and better matched to the work.
