Why the 609 Certification is Important
The Clean Air Act of 1990 requires auto technicians to be certified in handling refrigerants. Properly disposing of refrigerants helps protect people and the environment from harm. Without correctly recovering and recycling refrigerant, dangerous health risks are posed to humans and the global climate. An EPA 609 Certification allows industry professionals to understand and stay compliant with EPA guidelines in handling and disposing of refrigerants.
