Section 608 coverage focuses on who must be certified to handle refrigerants in appliances found in everyday buildings. The typical scope is the equipment used in homes and commercial settings—residential and commercial HVAC and refrigeration. That’s why Commercial and Residential best fits. Industrial or laboratory equipment and automotive systems involve different rules or separate certification paths, but the general Section 608 coverage described here targets the commercial and residential equipment technicians service.
