Summary
Operating as a licensed HVAC contractor in Oxnard requires compliance with both state and local regulations. At the state level, you must obtain a C-20 license from the California Contractors State License Board, which involves demonstrating four years of experience and passing comprehensive exams. Your technicians also need EPA certification for refrigerant work, and you must maintain substantial insurance coverage including general liability, workers compensation, and a contractor's bond. Locally in Oxnard, you'll need to register your business with the city and obtain mechanical permits for most HVAC work through the Building Division. The permit process is relatively streamlined, but inspections are required at key stages. Given Oxnard's location in Ventura County, you'll be working in a higher-cost market with opportunities for both residential and commercial projects, particularly given the area's growth and proximity to Los Angeles.
