/diy/ - Do It Yourself

There's not a lot of money in repairing window units because they're so cheap. You would need an EPA cert to be able to buy refrigerant also, which is likely most of the repairs you would be doing. Most window units don't even have ports to throw gauges on, so you have to buy special taps to get your gauges on. Even then, the units are "critically charged" meaning that just an ounce or two is enough too throw everything off. If you have enough knowledge and the proper tools to work on window units, then you def have enough to work on normal residential split systems. It's honestly pretty easy, what you can't figure out on your own you can figure out online. If you're going to go that route, don't be the local sheister.... If you're in over your head, say so and walk away from the job. You and the homeowner will both be better off in the long run. I don't know if I'd even suggest DIY hvac, there is a lot to learn and a lot if mistakes that need to be made, better that you're learning and fucking up as part of a company were experience and answers are just a phone call away.

EPA certs are really not that hard to get. Will cost you some money to have somebody proctor the test for you. There is 4 parts to the test , the Core Test, High pressure systems, medium pressure, and low pressure. (Referred to as parts 1, 2, and 3). You will need to pass core and also part 1 to be able to buy refrigerant.
IMHO, you're wasting your time if you're going to work on window units.
