Default A/C refrigerant noise on LS430 normal?

When the compressor cycles on, I can hear the refrigerant flowing at idle. The sound is like a quiet high pitched squealing. My wife said it sounded like water. The Lexus salesman and service advisor couldn't hear it. Anyone know if this is a common issue and if it's normal?

I haven't really heard of that kind of problem before. Just a suggestion though, why not try to have your whole A/C system cleaned and see if the noise will disappear.
