Environmental Protection Agency (EPA) MVAC Certification

What type of certification is required for over-the-road refrigeration units and R-22 air conditioning?

1. Section 609

2. Section 608

3. Section 610

4. Section 611

The correct answer is: Section 608

The correct answer is based on regulations that govern the handling of refrigerants in various applications. Section 608 of the Clean Air Act is specifically designed to regulate the use of refrigerants in larger systems, including commercial and industrial refrigerants such as those commonly used in over-the-road refrigeration units and R-22 air conditioning systems. Under Section 608, individuals who service, maintain, or dispose of equipment that can emit refrigerants into the atmosphere must be certified. This certification ensures that technicians are knowledgeable about environmentally safe handling practices and understand the proper procedures for managing refrigerants. Section 609, on the other hand, relates specifically to the servicing of motor vehicle air conditioning systems, while the other options do not correspond to relevant federal regulations regarding refrigerant handling in typical HVAC or refrigeration applications. This distinction is key in identifying why Section 608 is the appropriate certification for the systems mentioned in the question.
