In short
Every HVAC technician who handles refrigerant needs EPA Section 608 certification under federal rules. Beyond that, licensing depends on where you work. Some states license individual HVAC technicians or mechanics, many license HVAC contractors, and some leave it to local governments. Contractor licenses typically require years of experience, an exam on mechanical code and business rules, and insurance.
