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.
