Mainstream Engineering Offers EPA Section 608 Technician Testing
To work in the HVAC industry, technicians who maintain, service, repair, or dispose of refrigerant-containing equipment must be certified under the Environmental Protection Agency’s Section 608 of the Clean Air Act. Mainstream Engineering is a certifying agency for Section 608 Type I, II, III, and Universal certifications. This online resource can help you explore certification options, study, practice, and take the test online!
The EPA has developed four types of HVAC certifications:
- Type I Certification – For Small Appliances (5lbs or less of refrigerant)
- Type II Certification – For Medium-, High-, and Very-High Pressure Appliances
- Type III Certification – For Low-Pressure Appliances
Universal Certification – For anyone who possesses Type I, Type II and Type III Certifications
EPA-Approved Section 608 Certification is needed to service building air conditioning and refrigeration systems.
EPA Section 608 Technician Certification
Type I Certification – Can only work on Small Appliance (5lbs or less of refrigerant)
Type II Certification – Can only work on Medium, High, and Very-High Pressure Appliances.
Type III Certification – Can only work on Low-Pressure Appliances.
Universal Certification – Someone who possesses Type I, Type II, and Type III Certifications
Mainstream offers free study materials for Type I Open Book Certification online:
For technicians using the Type I Open Book format only, the exam is open-book, but the passing grade is 84% (per section) instead of 72% (per section) and the core questions must be repeated in a proctored environment if other certifications are later desired. We suggest the closed book exam! Click here to find a proctor location in your area.
608 Certifications for Servicing Air Conditioning and Refrigeration Systems
Before testing your knowledge of different types of appliances, you will need to pass the Core Section of your EPA 608 exam. The core section of this test discusses the purpose behind industry regulations and each technician’s responsibility to generate a safe and environmentally result. Your core exam section will contain a variety of topics, including a focus on ozone depletion, the value, and risks of refrigerants, the Three R’s (Recover, Recycle, Reclaim), safe practices, recovery techniques, and more.
Type I - Servicing Small Appliances
Available online in an open-book format, the Type I EPA 608 certification enables you to service smaller appliances. This section includes proper recovery techniques and industry requirements for small appliances, including recovery in equipment made before and after November 15, 1993. Moreover, there is a requirement to take the Core Section test; however, the test is an open-book, and the Core Section requires a proctored environment for future certifications!
Type II - High-Pressure Appliances
This EPA certification will enable you to service or dispose of medium to very high-pressure appliances, except in applications such as small appliances or air conditioners within motor vehicles. This education and training focus is geared more toward leak detection and how to test equipment properly. Type II also focuses on recovery techniques and requirements to minimize loss or cross-contamination.
Type III - Low-Pressure Appliances
The proper servicing and disposal of low-pressure appliances require Type III certification; however, it is essential to know that this near-identical exam is different from Type II in that low-pressure systems work in a vacuum. Therefore, leak tests and proper pressurization are crucial components of low-pressure HVAC services.
A technician that completes and passes all three certification exams will receive a Universal Certification. You will have to be tested on each of the three certification types in addition to the core exam. Expect to answer 100 questions in total.
