Hello. You likely need to [pressurize the refrigerant]https://www.yourmechanic.com/services/heating-ac-inspection) in the system properly. Unfortunately there is no way to test the system without hooking up gauges and physically testing it. If you have recently filled the system, there may be a leak. This would need to be repaired first. When you hook up a set of professional gauges, or have the system tested by a mechanic, they can test for pressure loss and make sure the system is closed. You can purchase charging kits at most automotive stores that will accomplish the basic job of adding refrigerant. Again the symptoms sound like the climate control us working perfectly fine, minus the fact the air is not getting cold enough. In this case, you are low on refrigerant and will need a recharge.
