you should evacuate and refill but you can get away with filling it back up

if there was a hole in one of the lines there's probably not going to be any refrigirant in the system. you can fill it but make sure you use the right gauge b/c you need the exact amount in there.

How would one evacuate an ac system? I am also looking to recharge my ac system. There's one I can get with a hose and pressure gauge with 3 bottles for $39.99 locally.

Okay to evacuate a system it has to be run in a vacuum for about 30 minutes or so. 30kpa of vacuum. It should hold that vacuum for about 15 minutes or so if there is no leak in the system. I would also recomend replacing the receiver/drier found behind the inner fender cover on the drivers side.

if you dont evacuate , system could have misture and air pocket due to leak,,if you dont have tools to do job take it to shop have the job done right if you want your a/c to cool at its peak ,it is not that expensive you got r134a the cheap refrigerant to do an a/c service and add 1 lb freon it will probably cost $ 30-50,,, look for sales

It may not work at all. Depends on how much moisture is in the system.

i would evacuate it AND repalce the receiver/drier. moisture in the system and air pockets will cause it to either not work, or not cool and possibly do more damage later on.
evactuating isnt much workand you can even take it to a shop and ask them to evacutate it and it wont cost a lot. having them evacuate it and you refill it is a lot cheaper than paying someone else to do it again after yo dont do it right the first time.
