HANDS-ON A/C SYSTEM SERVICING FUNDAMENTALS
TROUBLESHOOTING, MAINTAINING & SERVICING
TOPICS:
….Refrigeration and Air Flow System Servicing
….Hands-on Electrical Troubleshooting
….EPA Refrigerant Recovery Certification
WORKSHOP FEE: $345.00
(Includes EPA Exam Fee)
This 3-day workshop provides training on refrigeration fundamentals and refrigeration systems applied to residential and light commercial air conditioning systems, reach-in refrigerators and freezers, and walk-in coolers. In the hands-on electrical portion of the workshop, participants will wire circuits and use test equipment to test HVACR system electrical components. Detailed training is also provided on the proper use of test equipment and electrical safety. In the refrigerant handling certification portion of the workshop, EPA regulations and guidelines, recovery procedures, leak repair requirements, and evacuation and dehydration are covered in preparation for the 100-question multiple-choice exam. Throughout the workshop and certification preparation training, take-home interactive and detailed workbooks and manuals, which can be used later as a reference on the job, are issued to each participant.

ABOUT YOUR INSTRUCTOR…
Jim Johnson has been a full-time technician as well as a full-time trade school and community college instructor and administrator in the refrigeration, HVAC/R and appliance fields since 1973. He has facilitated over 200 training seminars in the HVAC/R electrical and refrigeration areas alone, as well as many other workshops in both technical and non-technical areas.
Jim takes the time to explain theory to you, but it’s not dull or boring. You learn what you need to know and understand what you need to understand because Jim explains it in a clear, simple manner that eliminates the mystery behind the subjects of electricity and troubleshooting. His background includes a satellite training network for HVAC/R and appliance technicians and the development and presentation of more than 75 video training sessions. Many of the video programs he has written, developed and presented contain interactive workbooks.
He is nationally recognized as one of the HVAC/R and appliance industry’s best-known technical writer and instructor, having written four textbooks for the HVAC/R industry and 10 technician handbooks… but he is quick to caution people that they shouldn’t be too impressed by that fact.
"Book learning is good stuff, no doubt about it," he says, "but until you put that knowledge to practical use, it isn’t worth much."
Jim is also a regular columnist for Indoor Comfort News and he has been providing their troubleshooting feature for over eight years. He has also written more than 300 feature articles for trade magazines.
Jim’s favorite saying?
"This stuff ain’t rocket science."
Jim allows plenty of time for questions and he encourages everyone in attendance to ask about anything they need to ask about. Students and workshop participants over the years have consistently rated Jim’s ability to communicate and explain things clearly as excellent. He is a member of RSES and ACCA, and is NBI-Certified as a Residential and Light Commercial Air Balancing and Diagnostic Technician.
Workshop Fee: $345.00 Includes all necessary workshop materials, take home manual, and EPA Refrigerant Handling exam grading fee. All necessary tools and supplies are provided. You're welcome to bring your own hand tools and test equipment if you prefer.
