An increasing number of businesses are requiring applicants to have an EPA certification in order to qualify for their positions. Furthermore, the certification is a federal requirement for anyone who works with refrigerants or refrigeration systems. Anyone who completes the EPA examination and certification process has an increased understanding of the numerous laws and regulations that are associated with handling HVAC chemicals. There are different categories of EPA certifications, but this article will discuss the EPA Section 608 certification.

There are four different EPA Section 608 certifications. The specific certification you hold will dictate which appliances you are allowed to work on. You must pass the appropriate EPA exam to be awarded any certification. You can opt to take only one test for a certain certification, or take them all to be qualified to work on any appliance.

What Is EPA Certification?

EPA certification is a requirement for anyone who handles or purchases refrigerants. These include ozone devouring CFC refrigerants such as R-22, R-11, and R-12, and to the majority of substitute refrigerants such as HFCs. Certification requires passing a written EPA refrigeration test specific to their specialty. There are four EPA certification levels. These are Type I, Type II, Type III, and Universal.

For all levels of certification, you need to first pass the Core Section of the EPA examination. This covers areas applicable to any job with refrigerants. The core exam covers ozone depletion, section 608 regulations, Clean Air Act and the Montreal Protocol, refrigeration, substitute refrigerants and oils, dehydration evacuation, shipping, recovery techniques, safety, and the three R’s (recover, recycle, reclaim). The core is comprised of 25 questions, and you must get at least 18 correct.

Type I Certification – Small Appliances

Type I grants the authority to work on small appliances. The open book test is comprised of 25 questions covering safety, recovery requirements and recovery techniques. You must get at least 21 of the questions right to pass.

Type II Certification – High-Pressure Appliances

Type II certification grants you the authority to dispose of or operate on high and very high-pressure appliances, not including small appliances and vehicle air conditioning. The exam covers leak detection and repair requirements, recovery requirements, recovery techniques, safety, and refrigeration.

Type III Certification – Low-Pressure Appliances

Type III certification grants you the authority to dispose of or operate on low-pressure appliances. The subjects covered in a Type III exam are the same as those in Type II. The Type III test is similar to the Type II. However, Type III is concerning low-pressure systems. Although a lot of the terms are similar, the dynamics of low-pressure systems are very different.

Universal Certification

Universal certification grants you the authority to work on all kinds of equipment. You can service high and low-pressure equipment and small appliances. In order to achieve Universal certification you must pass all sections of the EPA 608 Technician Certification exam, core, Type I, Type II and Type III. This all-inclusive exam is comprised of 100 questions, 25 per each section.
