Whistling nosie from AC

I have a 2005 EXT and lately when the air is on i've been noticing a whistling sound. It is not constant but is on and off in an irregular pattern. It's very annoying and very audible. It's a squeak, whistle. It's faint, but noticable. Had it to the dealer twice--they hear the sound but can't find anything wrong. What gives?
