Do you have to replace the AC compressor when changing the serpentine and relay

What is your question?

2008 Toyota Solara 1118 miles car in good condition. The AC is working fine but the serpentine belt is squealing even louder when you turn on the air. It was adjusted a few years ago but now it is much louder. I was told to lube it but another mechanic said no I have to replace the compressor too. Per Toyota the Solara has 2 belts.

What makes this problem better or worse?

It's worse when I turn on the air

How long has your 2008 Toyota Solara had this problem?
