Up until recently my air conditioning worked great. All of a sudden it started failing, and I have no idea why. I'm not an expert by any means, but I at first thought it might be the evaporator. This turned out to be unlikely as I measured the system, and from system off, even going on 10 minutes of running (heard the compressor click on), the low side never dropped more than 5psi. Any ideas? I'm thinking the accumulator now, or could it be anything else?

What is the low side hide side readings running and what is low side at rest pressure. Also what is vent temp?
