My AC isn't be blowing very cold air and I'm guessing it just needs to be recharged (it's a 2013). Can I just use the stuff in a can (that you can buy any auto store) and do it or is there something more to the process?
AC systems are tricky: the first question is, do you know where you’re losing the refrigerant, or even if the AC is cycling on to blow cold air? Replacing refrigerant is the uninformed, very short term approach to try and fix something, which may not be broken, or if it is, needs more than just refrigerant. I like NA engines, and am not concerned about CO2, but refrigerant is a real pollutant, and should not just be added if there’s a leak, as you’ll just leak more. If you are low on refrigerant, then you probably have an old o-ring that’s brittle and needs to be replaced. I would recommend a shop or dealership, since they have the tools to properly find the leak, fix it, vacuum, and then refill the proper amount of oil and refrigerant into your system.
It still blows "cool" air just not cold. It hasn't been done since new so I thinking it just needs some to be added. I think over time it just evaporates.....

Most likely you are probably right. A good HVAC shop can connect gages up at various points and determine if you are low on fluid. However to the previous point, being low on fluid may also mean there is a leak somewhere. Most likely the shop will begin with a re-charge if necessary and also a soap "snoop test" to look for bubbles and a leak.

No, it does not evaporate with time unless theres a leak.
I had the same issue. It ended both my condensers had small hole from rocks. You need to add a fluorescent dye, then inspect with a black light for leaks.
