To ensure compliance with refrigerant recovery and recycling regulations, HVAC-R professionals should familiarize themselves with local, national, and international regulations, such as the Clean Air Act and the Montreal Protocol. They should also maintain accurate records of refrigerant recovery and recycling activities, use certified recovery equipment, and follow industry best practices and guidelines. Additionally, technicians should obtain necessary certifications, such as EPA Section 608 certification, to perform refrigerant recovery and recycling tasks.
