Welcome to Allpar. You should be very leery on adjusting the refrigerant amount in the system unless you have a good reason to. If the system is low, you have a leak that has to be addressed first.
You may be able to view the gauge set while going down the road for when it is acting up. That is the time when you want to diagnose this.
The instrument cluster (CCN) is the module that controls the A/C system. It can store fault codes and offer sensor information that may help in diagnostics. You may need an advanced scan tool to access this information. If the evaporator is icing up, you will lose cooling while driving.
The TIPM and PCM control the compressor which is engaged all the time. The displacement is varied according to A/C demand. These modules also can store fault codes and system information.
