Become a member of MACS!

The Mobile Air Conditioning Society (MACS) Worldwide has been the advocate for service and repair owners, distributors, manufacturers and educators making their living in the total vehicle climate and thermal management industry since 1981.

MACS Worldwide empowers members to grow their businesses and delivers tangible member benefits through industry advocacy with government regulators and by providing accurate, unbiased technical information, training products, training curriculum and money-saving affinity member services.

MACS produces award-winning industry publications ACTION magazine and MACS monthly technical newsletter, MACS Service Reports to keep members informed with factual information. These publications are archived on the MACS website for member research.

MACS has pioneered and facilitated the Section 609 certification program that has allowed more than 1.1 million service technicians to comply with the U.S. Clean Air Act of 1990 requirements for certification in refrigerant recovery and recycling to protect our environment.

MACS continues to lead the way forward with a revision of our Section 609 certification program to educate service technicians in the safe handling of R-1234yf.

MACS holds an annual Training Event and Trade Show for an intense three day training gathering and many regional training clinics throughout the calendar year. In 2018, MACS Training Event A/Ccess will take place February 14-17 at the Caribe Royale Hotel and Convention Center in Orlando, FL.
