Meet the teacher
Continuing our series of blogs introducing some of the teachers that will be presenting classes at the upcoming MACS Training Event and Trade Show in February. Each of these class leaders has been chosen for their detailed knowledge of their topic and their ability to present it to you.
Kermit Walden, Trans/Air Manufacturing
“Bus A/C systems”
Bus A/C systems can pose unique challenges when it comes to locating and repairing leaks. Anyone working in this specialty field needs to meet this instructor.
Kermit Walken is a field service technician for TransAir Manufacturing and his duties include field service repairs throughout the United States, conducting classes on installation, maintenance, diagnostics, and repair of TransAir systems, fielding technical calls, and assisting customers and other technicians with diagnosing and repairing systems. He’s spent the last 20 years installing, troubleshooting, and repairing A/C systems on buses ranging from small shuttles to large transit buses.
What’s this session all about?
Kermit replies, “Through the years I’ve learned a lot from mistakes made by others as well as my own. Mistakes, however costly, aren’t always a bad thing if you learn from them. My goal in this class is to help you avoid making the same mistakes in the first place by sharing what other technicians and I have learned.
“Having started out in the bus air conditioning industry as an installer, I’ve learned the “ins and outs” of hose routing in different applications, as well as the problems they can pose. I want to share with you some ways of systematically locating the leaks and deciding the best way to repair them and assure that they don’t reoccur.
“I’ll also be explaining how evacuating, leak testing and recharging the larger bus systems differ from the smaller systems found in the automotive industry and how to properly perform these tasks in ways that could save you time, aggravation, as well as money. I hope to see you there.”

When having your mobile A/C system professionally serviced, insist on proper repair procedures and quality replacement parts. Insist on recovery and recycling so that refrigerant can be reused and not released into the atmosphere.
