The former Refrigeration Service Engineers Society has a new set of training DVDs and CDs available.

The materials were created by Jim and Peggy Johnson of Technical Training Associates and cover HVAC topics for beginners and longtime industry workers, officials said.

“The products offered by Technical Training Associates provide top-of-the-line in-depth instruction, content and illustrations that today’s HVACR contractor or service technician will encounter in the field, and focus on equipment and theories that are extremely relevant to the industry professional,” said RSES director of publishing, John Iwanski.  “Jim Johnson’s monthly Troubleshooting column in the RSES Journal is one of the most popular features with readers, and the same systematic approach to figuring out how to solve problems and understand theories on heat transfer, refrigeration, and electrical components can be found in these DVDs and CDs.”
