The amount of refrigerant controls the pressure in the evaporator. That dictates the boiling point temperature. The amount of charge should be the first thing checked. Many will do this DIY.
Suggest 33-35 PSI, hood up, doors open, recirc off, max cool, max fan. The sight glass will show bubbles and will not be free of them when properly charged. To be bubble free, the pressure would have to be higher and that would be overcharged and the cooling effect cool instead of cold.
