Fuck man... I could be wrong. You will have to look it up, it's been a bit so I'm afraid I might be misremembering. You might need a universal EPA cert, which means passing all of the tests, to be able to buy refrigerant. I believe it's just Core and part 1 though. Just Google it and you will find out easy enough. The test is simple. I passed it the first time only missing 2 questions. Hell, I still have the flash cards I made to study with, send me a few bucks for shipping and your address and their yours. There's like 400 of them... Seems like a lot but it's easy shit. Good luck in your endeavors, anon.
