I still think it is worth getting the A/C charge checked out, even a system 50% full will still blow very cold but the trinary switch will be struggling to get enough pressure. It could even be a dodgy trinary switch, I had one to fix recently that one day was ice cold and another it was reacting like it had no refrigerant, a knock on the trinary would bring it back to life.

Some places advertise they wont charge unless they make your system x degrees colder so if there is nothing wrong it wont cost.
