Checking A/C the right way?

Help me settle a disagreement. A customer comes in and says "My A/C isn't working, can you take a look at it?". We pull the car in and see that the compressor clutch isn't engaging. We hook up the A/C machine and see that there's about 75 PSI in the system on an ~80 day.

What's the next logical step? Check the electrical side and see why the compressor isn't coming on, or evacuate the system to see how much refrigerant is in it? (or something else?) A brief explanation of the answer would be appreciated.

Thanks,
Jason
