Taking the EPA Section 608 certification is a crucial step for anyone who wants to work in the HVAC field. It may be possible that you’ll never have to handle refrigerants, but that’s unlikely since they’re essential not only for food cooling systems but also for air conditioning and related systems on homes.
Successfully passing this test gives you a lifelong license to be able to buy, recycle, reclaim and recover the refrigerants you’ll want to work with. It’s also good across the country - so if you decide to move to another state, you’re still covered.

The Testing Structure
As you probably know, there are 3 types of Section 608 certification, plus the universal level which includes the other three. It’s up to you to figure out which Type to prepare for. Obviously, the most all-purpose license is the Universal. But if you are sure that you’ll only be working with certain types of units, you can take one of the other types.
Each of the 4 exams - Type I, II, III and Universal - consists of a section especially for that area, as well as a core section. The core section covers material that is relevant to any area.
Core Exam Contents
The EPA Section 608 core exam’s focus is on things you need to know for all the other areas. These include
- Important historical information and regulations
- Clean Air Act
- Montreal Protocol
- Section 608 regulations
- Ozone depletion
- Recovery, Recycling and Reclaiming
- Substitute refrigerants and oil
- Shipping regulations and best practices
- Recovery Techniques
- Dehydration Evacuation
Knowing key dates is important. Of course it’s also essential to understand the harmful effects that refrigerants can have when not properly handled.
Type I Exam Contents
The Type I exam is the only one that is open book. It can be taken online from home, even. But that comes with a price - you have to get a grade of 84% to pass, compared to 72% for the other exams. It covers small appliances and focuses on these areas:
- Recovery Techniques and Requirements
Type II Exam Contents
Type II deals with high-pressure equipment. We recommend you take this exam even if you don’t think you need it. If you take Type I and later decide you want Type II, you’ll have to take the core exam over again in a proctored setting.
The subject areas for this exam deal with high-pressure devices and focus on:
Type III Exam Contents
If you plan on working with low-pressure devices, Type III is the exam you’ll need to take. To be ready for this, you’ll need to study the following areas, especially as they relate to low-pressure devices:
- Recovery Techniques and Requirements
- Recharging Techniques
- Leak detection and repair
All of the above areas are part of the universal exam. You’ll have to take the core exam plus the universal exam, which draws from all the other areas. It’s definitely tougher than the others, but it also gives you greater opportunities.
How To Best Use These Practice Tests
Our practice tests are designed to help you get the feel for exam material. The questions on the exams are similar to these. We encourage you to use them to help get you ready for the real thing.
Here’s some tips for taking the tests:
Study first. Be prepared to take the exam before you try it. Remember, we’re using possible exam questions. We might not have covered every possible question or possibility. Don’t limit yourself to knowing just the info in the practice tests.
Set aside time to take the quiz. Take the quiz when you can dedicate the appropriate amount of time to it. Try to work in a quiet environment where you won’t be disturbed - similar to real exam conditions.
As far as possible, try to take the tests without looking the answers up. You won’t be able to do it on the real exam, so it’s good to get in practice.
Take the exam until you’re comfortable with your grade. Our site lets you take the exam as often as you want.
Don’t forget to take the core exam. Remember to practice the core exam, too. Both it and your area-specific exam are necessary to receive your certification.
Section 608 certification is a great way to get your career underway, and is almost indispensable unless you want to seriously restrict your usefulness as an HVAC tech.
