A Section 608 certification allows a technician to purchase or handle controlled refrigerants, a requirement for HVACR maintenance or service tasks. It does not permit importing R-22 or authorize work on all HVACR systems without other required certifications.
A Section 608 certification allows a technician to purchase or handle controlled refrigerants. This is essential for those involved in the servicing, maintenance, or disposal of equipment that could release refrigerants into the atmosphere. It does not permit the importation of R-22 from overseas, which is a separate regulatory matter.
Also, while this certification is necessary to service motor vehicle air conditioners to some extent, more specialized certification (Section 609) is needed for that specific task.
Finally, holding a Section 608 certification does not authorize a technician to perform work on any type of HVACR equipment without regard to their individual qualifications, local laws, and additional certifications that might be required for certain types of work.
