I'll throw in my .02 at this point as well.
Modern cars are not cars of old that could just be manhandled under shade trees. If your modern car's AC is not working properly you don't just screw on a can and add it. You don't have a sight glass, so you need a manifold gauge set to do the job properly. And it could easily be a sensor issue, line constriction/deterioration or saturated dryer, and not low refrigerant.
If you just add a can of refrigerant to it and it's not low, you will in fact DAMAGE the system, perhaps getting to buy a compressor, hose or other component. The cost of repairing the mistake you make -- assuming you're not also injured in the process -- with exceed by many, many times the cost of taking it in and having it done properly by someone who knows what they are doing.
Moreover, most shops will also do a leak check, if you're low on refrigerant it has to be going someplace. Then it is actually fixed and you don't have to continue to add refrigerant.
Take care and enjoy the ride,
