Modern Automotive HVAC Boot Camp


There was standing room only when MACS Instructor Larry Turay taught an air conditioning Boot Camp at the MACS Training Event and Trade Show last year. During the break, Larry was out in the hall when a young man wearing clean shop clothes came up, introduced himself as Ron and said,

“Somebody told me I should take this class tomorrow morning. Can you tell me why I should attend yours and not the one I had planned? What makes it so good? Why do I want to be there and what’s in it for me when I go back to the shop? What do you do for 3 hours?”

Larry replied, “Well Ron, any of the classes you attend at the MACS Convention will be well worth your time. If you decide to attend mine you will find that the class is relaxed and informative, yet  fast-paced program and filled with tips, tricks, pointers and humor. The three hours will feel like thirty minutes, and what you’ll learn can be applied immediately when you clock in on Monday morning!”

Having been in Larry’s class that day, I can vouch for everything he said. Larry is an experienced teacher who knows how to communicate effectively with a room full of adults. He has a way of explaining things that make a complete novice and a seasoned expert both nod with acknowledgement and understanding. When people asked questions, Larry used it as an opportunity to get other people involved in the conversation. Keeping an audience interested and entertained for three hours is a skill that’s equally as important as the material being presented, because that’s how people remember what they hear.

In addition to knowing how to teach, Larry has also walked the walk. He worked as a tech and a shop foreman before moving into education as a high school teacher, post-secondary school instructor and college professor. As a professional trainer, he has been director of training for Everco Industries, training manager for Moog Automotive, field training manager for Four Seasons and field service trainer for Freightliner. He keeps up to date by researching and writing articles on A/C repair for various trade publications and has co-written the two textbooks on modern automotive HVAC and electrical systems currently available through MACS (
