What is the Difference Between EPA 608 and 609 Certification?

Are you curious about the distinction between EPA 608 and 609 certification? Both certifications are necessary for different types of cooling systems, but the most important difference is the type of cooling systems they cover. EPA 608 certification is required to purchase non-exempt or ozone-depleting substitute refrigerants, such as HFC refrigerants. This certification applies to stationary refrigeration and air conditioning systems used in buildings. On the other hand, EPA 609 certification is needed to purchase CFC-12 or EPA-approved substitutes for MVACs that contain ozone-depleting substances.

This certification covers mobile air conditioning systems, such as those used in vehicles and portable air conditioning units. In a nutshell, individuals certified under the EPA 608 program are qualified to work on cooling systems used in buildings, while those certified under the EPA 609 program are qualified to work on vehicles and portable air conditioning units.
