California Class C Air Conditioning Contractor (CA) California’s Class C air conditioning contractor exam assumes you’ve completed EPA Section 608 certification and logged practical hours handling refrigerant systems. Without baseline knowledge of thermodynamics, electrical circuits, and local Title 24 energy codes, you’ll find the technical sections—particularly those covering heat pump diagnostics and ductwork design—significantly harder. Many candidates underestimate how deeply the exam probes California’s specific licensing requirements and safety standards.
