well if you took it to the dealer we have no way of just adding more refrigerant. system has to be recovered first then they pull it into a vacuum and monitor for leaks. then they will charge it and visually inspect for leaks. then use a "sniffer" which detects refrigerant to look for leaks. At least that's how I do it. That crap in a can is exactly that, crap. Any shop that does ac work will do it right. Just monitor it and if it starts to blow warm again have it re checked for leaks. If they were smart they would have added leak tracer dye to the system which shows up really good under black light if theres a leak.
