608 Certifications for Servicing Air Conditioning and Refrigeration Systems

Before testing your knowledge on 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 focuses on ozone depletion, the value and risks of refrigerants, the Three R’s (Recover, Recycle, Reclaim), safe practices, recovery techniques, and more.

Type 1 – Servicing Small Appliances

Available online in an open-book format, the Type 1 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. Keep in mind you will also need to take the Core Section test, but since it is open-book, the Core Section will need to be taken in a proctored environment for future certifications!

Type 2 – 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. The focus of this education and training is geared more toward leak detection and how to properly test equipment. Type II also focuses on recovery techniques and requirements to minimize loss or cross-contamination.

Type 3 – Low-Pressure Appliances

The proper servicing and disposal of low-pressure appliances requires Type III certification, but it is important to know that this near-identical exam is different from Type II in that low-pressure systems work in a vacuum. Leak-tests and proper pressurization are an essential component of low-pressure HVAC services.
Universal Certification

Technicians who pass all three certification exams will be awarded 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 total.

What is the EPA 608 Test?

This certification exam is designed to educate HVAC technicians in various methods and refrigeration products, providing a safe and eco-friendly outcome with each service. Each section of this test includes 25 questions, equating to 100 questions for a complete certification.

Individuals working to earn their 608 certification must do so under the guidance of an EPA-approved certifying organization such as Mainstream Engineering.

How Hard is the EPA 608 Test?

For those who do not study, passing the EPA 608 exam may prove challenging. Technicians who prepare and study will likely pass the exam without too much worry. Be sure to review your study manual and memorize the proper information. This will help to reinforce your in-field services later on.

Is There a Difference Between a Refrigeration EPA Certification and an HVAC EPA Certification?

The difference in verbiage may cause some confusion, but these two terms are interchangeable in EPA terminology. AC systems rely on refrigerants to complete operations, and therefore fall under the umbrella of EPA 608.
