Understanding EPA Certification Concepts

Robert Stringham introduces a video series for EPA Certification 608, initially aimed at his students but now reaching a wider audience. The series covers thermodynamics, refrigeration cycles, refrigerant charging, safety, and regulations. It includes practical lab activities and addresses different types of refrigerant certifications. Despite some quality issues, the videos have successfully certified many technicians over 15 years.
