I have put together a study guide for the EPA 608 Type 2 test that will get you prepared to take the test. All of these questions are relevant knowledge that you should know and I’d suggest taking this test as many times possible until you get all of the questions correct. I’d also suggest checking out the EPA 608 core practice test as well since you will have to take the core along with the Type 2 test. Both of these tests will need to be passed before getting your EPA 608 certification.

My name is Bob Wells and I am a retired HVAC tech from Washington state. I am currently retired and no longer do much with HVAC, however, I feel like I have a lot of knowledge in the subject and I wanted to create a website where I could talk about what I've learned and help upcoming HVAC techs.
