So, here's the deal. I want to recharge it
myself. I don't know anything specifically about air conditioners,
but I am an engineer and I have lots of tools and instruments. Can
someone please explain to me a general synopsis of what I need to know
in order to recharge my AC.

So here's the deal. You can't. Unless you have a license, you can't buy
the refrigerant. You also need a couple of hundred bucks in equipment to do
the charge. There are gauges specific to refrigeration and charging.
