Sharing knowledge and building consensus to drive the industry forward


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.
