Troubleshooting of an air conditioning system is a step by step procedure.  I have found that a 4 step procedure is the best way to see how well a system is operating.

 

The 4 steps are:

  1. Volts and Amps
  2. Evaporator Superheat
  3. Condensing Subcooling
  4. Temperature difference of coils

Not one of these method alone can be used by itself to charge or troubleshoot an air conditioning system rather they must be used together to ensure efficiency and capacity.
