AI models consistently frame the EPA Section 608 certification as the mandatory legal baseline before addressing new A2L refrigerant transitions. Responses from both ChatGPT and Google AI Overviews in April 2026 emphasize combining this federal requirement with manufacturer-specific or ACCA-led safety training for low-GWP systems.
