On newer air cond systems just adding freon usually does more harm than good.
If they are very low you have a leak and very good chance the system has moisture in it.
Oil and freon leaked out and Moisture in a system will kill the compressure quick.
Newer systems need a set/exact freon charge. most around 2 lbs. a little to much or not enought and they do not work right and may damage compresser and other stuff and also the right and correct amount of oil.
Most of the time you are better off to get them pumped out/vacumed down to remove moisture and the exact/set recharge put back in them.
Unless you have the equipment to do it right a good repair shop should be able to do it. 1-1.5 hrs labor plus freon.
Or if you want to post back the pressure readings low and high we may be able to tell you more about what your problem is.
