Could be low on refrigerant. The correct way to determine this is to recover the old refrigerant and determine how much was recovered by weight and compare what a fully charge system should be by weight. The difference is how low the system is.

Mistermetoo- i had exactly same problem, but nothing already mentioned in this thread was solution for my problem. It was broken water valve in A/C system. after replacing it A/C working again.
