If the A/C is still delivering cold air, your refrigeration charge is probably just fine. DO NOT adjust the charge. DO NOT remove the R12 and replace it with R134a unlees you want to be disappointed in A/C performance.

Most likely you have belt slippage from a glazed/worn belt or failing belt trnsioner. You may also have a clutch slippage problem, and would have to clean the external oil and grime from the clutch to solve that.

Open the hood with the engine running and cycle on the A/C. Tou'll almost be able to see if the belt is slipping. Apply some belt dressing (carefully) to see if the belt is slipping and if the noise changes.

DON'T spoil your working A/C system because of a slipping belt or clutch.
