If the compressor continues working, that tells me the AC is working. If you are losing cold air in the vehicle, it tells me there is a problem with the blend air door. The door is located near the heater core. Its purpose is to determine if you get heat or AC. If it is closing due to vacuum loss or a malfunction. That is where I would start.
Let me know what you find.
