route How to become an hvac technician in California
To become a licensed HVAC Technician in California, individuals must obtain a C-20 Warm-Air Heating, Ventilating and Air-Conditioning Contractor license from the California Contractors State License Board (CSLB). Key steps include demonstrating four years of journey-level experience within the last ten years, passing both the C-20 HVAC Trade Exam and the Law & Business Exam, and submitting a comprehensive application with a $450 fee. Applicants must also be at least 18 years old, undergo a background check, secure a $25,000 contractor bond, and provide proof of EPA Section 608 Certification and workers' compensation insurance. California offers reciprocity with Arizona, Louisiana, and Nevada, potentially waiving the trade exam for qualified applicants from those states.
