Summary
Operating as an HVAC contractor in Santa Rosa requires both state and local compliance. At the state level, you'll need a California C-20 license from the Contractors State License Board, which involves demonstrating experience, passing exams, and maintaining continuing education. Locally, you must register your business with Santa Rosa and obtain permits for most HVAC work through the city's Building Division. The permit process is straightforward but requires proper documentation and inspections. Insurance requirements include general liability and workers' compensation coverage, plus the state-required contractor's bond. The Santa Rosa market offers good opportunities for HVAC contractors, with strong demand for both residential and commercial services driven by the area's climate needs and ongoing construction activity.

The license must be renewed every 2 years with 32 hours of continuing education. Additionally, contractors must register with the City of Santa Rosa as a business and obtain a business license. For refrigerant work, EPA Section 608 certification is required.
