A/C REFRIGERATION & ELECTRICAL SYSTEM TROUBLESHOOTING
This training experience explores the fundamentals of maintaining, troubleshooting and servicing air conditioning systems from a nuts and bolts perspective.
WHO SHOULD ATTEND:
In the hands-on refrigeration system portion, participants will use gauges and a temperature pressure chart to evaluate operating systems, use recovery equipment, vacuum pumps and re-charge systems.
In the hands-on electrical portion, participants will use digital and analog meters to test electrical system components, and wire actual circuits from schematic diagrams.
As a workshop participant in this hands-on HVAC training workshop you will have the opportunity to build your own personal foundation of understanding of the fundamental concepts of electricity, refrigeration and air flow in comfort cooling systems, then apply that information to develop effective troubleshooting skills.WORKSHOP SCHEDULE: BOTH DAYS 8AM To 5PM

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 300 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 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 ten years. He has also written more than 500 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.
The bottom line?
Jim teaches you what you need to know and makes sure you have some fun in the process.
