Who actually needs EPA 608 certification?
Section 608 of the Clean Air Act requires any technician who maintains, services, repairs, or disposes of equipment that could release regulated refrigerants into the atmosphere to hold certification. That includes HVAC technicians, refrigeration technicians, and anyone else who works on covered equipment — regardless of employer size or how often they do this kind of work.
The four steps to certification
1 Decide which certification type you need
Certification is split into Core, Type I, Type II, and Type III. Which ones you need depends on the equipment you actually work on — small appliances, high-pressure split systems, low-pressure chillers, or some combination. Many technicians choose Universal certification to cover all three Type categories at once.
2 Study and prepare
Once you know which sections you need, study the material specific to those sections. Our free study guide breaks down exactly what's covered in each section, and our free practice test shows you which areas need more work before exam day.
3 Take the exam
The exam can be completed in person at a testing center or through remote online proctoring — see how online testing works if you're considering that route. Each section requires a minimum score of 70% to pass (some open-book formats require 84%).
4 Receive your credential
Once you pass, your certification does not expire and does not need to be renewed. It's yours for the life of your career, regardless of how many employers you work for.
