SkillCat EPA Universal Practice Test

SNAP evaluates refrigerants for each specific appliance and use, weighing environmental impact, safety, and feasibility. It isn’t limited to blends that exclude HFCs. Some refrigerant blends containing HFCs have been, or can be, accepted for particular applications if they meet SNAP’s criteria, while other high-GWP options may be restricted or phased down. So the idea that only HFC-free blends are accepted isn’t accurate—the acceptance depends on the exact substitute and its intended use.
