Hello, my name is***** of the time if this occurred before with the AC system being used and now it does it all of the time then it may be a failure in the AC compressor itself. I usually start by removing the belts and spinning each pulley by hand to listen for the noise. If there is a loose belt this will occur also. I am suspecting the compressor though. I hope this helps. If you need anything else please let me know.
