It depends on your state. Many states require an HVAC contractor or technician license, while others regulate it at the city or county level. Everywhere in the U.S., though, you must hold federal EPA Section 608 certification to handle refrigerants.
States like Texas, California, and Florida require HVAC contractor licenses with experience and exam requirements, while a handful have no statewide license at all and leave it to local jurisdictions. Always check your specific state’s rules before working unsupervised.
Regardless of state licensing, the federal Clean Air Act requires EPA Section 608 certification for anyone who purchases or handles regulated refrigerants. It never expires and is the one credential every working HVAC tech needs.
Where a license is required, you typically need 2–5 years of documented experience (apprenticeship or supervised work), proof of insurance, and a passing exam score. Completing accredited training and an apprenticeship is the standard route.
