"Individuals who have made outstanding career contributions to the mobile A/C and heat transfer industry are recognized for their work with the Mobile Air Climate Systems Pioneer Award." Recorded Live at the 2024 MACS (Mobile Air Climate Systems) Training Event & Trade Show, Carm Capriotto discusses the automotive air conditioning industry with Peter Coll and Pioneer Award Winners Larry Hays, and Tom Massey. They explore the evolution of air conditioning systems, the importance of collaboration, and the role of MACS in advancing the industry. Larry Hays' career in automotive service began in high school when his shop teacher got him a job at an independent garage. Shortly thereafter, and while still in high school, Larry took a work/study job starting at 80 cent an hour and stayed there for 5 years before moving to Dallas Smith Transport. There he got his first taste of the A/C life learning to install factory A/C in a 1962 Buick and rebuild A6 compressors at the GM Training center in El Paso, TX. After three years, Larry found his forever home at Tony M. Coury Buick in Mesa, AZ where he would go on to spend the next 40 years. In 1966 Harrison Radiator introduced their own automatic A/C system and often visited Larry from the GM Proving ground due to his close proximity.  The visits led to friendships, networking and, eventually an introduction to the likes of Paul Weissler, Jim Resutek, Ward Atkinson, and many others. In 1976, Tom Massey, an ASE certified Master Technician, started his own shop in Sioux Falls, SD. Doing A/C in South Dakota in the 1980’s, Tom was frustrated because the one fitting that was needed for the job was not available locally so, Tom started stocking A/C fittings, A/C units and other parts to be available on demand. When other shops found out that he had inventory, the business progressed to add wholesale parts & distribution. He was a distributor for ARA, AIR & later for the company that became Global Parts Distributors. Tom’s passion for A/C drew him to heat of Las Vegas in 1993 when he started Auto Air & More Inc. selling A/C parts to consumers, fleets, dealerships, and competitors as well as servicing vehicles.
