The V2 revision contains three specific tables that are guaranteed to appear on the exam:

The international treaty phasing out ODS (Ozone Depleting Substances). 2. Clean Air Act Regulations

The 9th Edition V2 represents an updated iteration of this knowledge base, reflecting critical shifts in policy—most notably the transition from Chlorofluorocarbons (CFCs) to Hydrofluorocarbons (HFCs) and the ongoing phase-down programs (AIM Act). This paper dissects the manual’s core modules, providing a comprehensive overview for the aspiring technician.

Mastering the EPA Section 608 certification is a mandatory milestone for anyone pursuing a career in the Heating, Ventilation, Air Conditioning, and Refrigeration (HVAC/R) industry. Under Section 608 of the Clean Air Act, the United States Environmental Protection Agency (EPA) requires that all technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must be certified.

V2 places a massive emphasis on next-generation, mildly flammable refrigerants known as A2L refrigerants (such as R-32 and R-454B). Technicians must understand the specific safety, storage, and handling protocols for these low-GWP alternatives. Epa Section 608 Preparatory Manual 9th Edition V2 Pdf

Authorizes the EPA to phase down Hydrofluorocarbons (HFCs) by 85% by the year 2036 due to their high Global Warming Potential (GWP).

Once you pass, you will receive your official certification. Your credentials do not expire, but it is important to keep a copy of your certification at your place of business for up to three years after you are no longer operating as a technician.
