You likely will not be able to buy the freon, so just take it to a qualified service station and have them perform a leak test and then recharge the system. This is really not a DIY job, and needs to be done using the proper equipment by a trained and qualified service person.
1993 was the magic year that everyone stopped producing R-12 equipment. With yours being a '93, it could be either R12 or R-134a. If it's R-12, it has been illegal to buy or sell R12 since 2000, so no one is going to have it. If it's R-134a, the auto parts stores are going to have it, but I'm not sure if they will sell it to you unless you have an EPA card. Also, the leak would have to be found and repaired or you will be back to recharging, and since you don't know how long it actually took it to leak down, you don't know how large the leak is or if it's repairable.
