Answer
Kelly, thank you for your question.  Usually when an AC unit is not working it is because there is not enough Freon in the system.  Normally, it takes about 1 to 2 12 oz cans of R134a plus oil charge to pump up an AC unit.  Also another thing that can be the problem is a leak in the system.  Leaks are easily detected by use of Leak Detector.  It contains a red or other color dye that shows where your leak is.
Hope that helps
