Forty years ago, automotive service technicians who worked on mobile cooling systems needed a central place they could access for unbiased information. In answer to that need, the MACS Mobile Air Climate Systems Association was founded in 1981. Early on, our founder Elvis Hoffpauir, along with other technician trainers, traveled around the country hosting service training sessions. Their goal was to bring information and training from the OEMs to auto technicians and mechanics, so they could better serve their customers.
When the U.S. Clean Air Act of 1990 required service technicians to gain their EPA 609 Certification, MACS pioneered and facilitated the training program. Because of our outstanding EPA 609 Certification training course, MACS was the first organization the EPA recognized for its 609 Certification program.
