ps: They did mention something about my car running out of "Freon". As far as i know, Freon is R12. I could be wrong tho. Im not an expert on this subject. So i just have to figure out which kind of refrigerant my 93 240sx uses.

ok freon can be r12 or r134a.
Two totally different refrigerants.
r12 came in older cars, i know on hondas it was 94 when they first started puttin r134a in cars rather than r12 for several enviromental reasons. Back on topic though, Being it is 2013 and you just had this service done i can guarantee you that they put in r134a being r12/freeze12 is not very easy to get your hands on, let alone purchase(you must have certification from the state to purchase r12 nowadays).
It sounds to as if you are either under or over charged.
If your vehicle DID come with r12 and lets say it specified to put in 22 oz of r12 in it. Well that being said, if the mechanic installed 22oz of r134a then that is a problem right there. If the vehicle calls for 22oz of r12 than that means it would need 85-90% of that put in as 134a which would be 18.75 oz of r134a.
Also the desiccant inside the drier is not useable for r134a if r12 was previously used!
You must replace the filter drier/accumulator with one specified for use with r134a not r12 which is easily had being only 134a parts are sold nowadays.
So keep this all in mind and lets revamp this and hopefully you can figure out whats going on with your a/c system
