The first thing that needs to be done is to get a set of A/C gauges on it to see pressures. If the compressor is coming on or cycling there should be a pressure change. It is usually ~30 on the low side and ~190 on the high side while running and the A/C on. This will also help to determine if charge is correct. Both pressures should be equal with the A/C off. And usually when the charge is correct the pressure will equal the outside temp as a starting point. Example: 90 deg outside = 90 psi in the system.
