Answer
Hi Jp thanks for asking!
It is not necessary to cahnge freon at all, It doesnt wear out, the problem I think that you are having is a compressor clutch wearing out, The compressor will make a rattling noise when worn out with the ac clutch off because the clutch is not engaged and it is just free standing, When there is pressure on the clutch the rattling will stop.
Good Luck
