COOLING WHAT MOVES YOU
Thank you for visiting MACS!
Beginning at 8:00 AM Monday, December 11, 2023, some features of our site may display a Check Engine light as we swap out a Compressor, Condenser and Evaporator. Our technicians are diligent but slow so some functions will be out of commission until December 14, 2023. In the meantime, if you need any assistance at all, please call us at +1 (215) 631-7020.

Sharing knowledge and building consensus to drive the industry forward

2024 Training Event and Trade Show

Keeping the environment safe with a 609 Certification
Obtaining a 609 Certification ensures refrigerant can be recovered, recycled and disposed of properly. In addition, it keeps you in compliance with legislation and helps protect from fines.
One important note: 609 Certification is not skills training. Rather, it gives individuals the required knowledge on federal laws regarding the mobile climate control industry.

Empower with mobile air climate systems training
Whether diagnoses are inaccurate or customers have multiple comebacks, MACS customizes training to workers’ unique needs. With practical knowledge they can immediately utilize, industry workers will be empowered to get jobs done right—the first time.
Choose from in-person training at your facility, using your vehicles, or live online training.
