I got my EPA 608 universal for free after 2 night of cramming and an online proctored test. Skillcat, I think they charge like $50 if you want a printed card, worth it to me because I wanted to be able to walk into supply houses and buy refrigerant.

I almost did this after I helped a friend install a mini-split.

Having just installed a mini-split in my office shed with a pre/charged unit. I told him it was easy and helped him. We ended up needing to buy an extra long line set to make the distance work, which needed more refrigerant.

I called 15 different places and finally found one that could come out and charge the line for under $350. Which was hard to stomach with the whole unit costing only $750 from Amazon.

I always wondered how difficult it was to do this. I’m really glad to know it’s possible

Getting the 608 is mostly rote memorization and the only thing required at the federal level. On the state level if you want a trade license that generally takes 4 years, but where I live residential owner-builder doesn't need it.

608 lets you buy the refrigerant

Me too, except I got it in the SkillCat free trial. Did it while rocking my then baby over a few weeks. Super easy for anyone that is a “good” test taker and has high school level reading
