Can anyone else with the 6.2L hear the AC compressor at idle and while accelerating?

Took it in for them to check and of course the tech said he couldn’t hear it.

 

Sounds like mine is either over or undercharged. Might put my own gauges on them to check...

Ok today I heard it in my 5.3 Silverado work truck. Maybe I’m being too picky coming from a powerstoke where all I heard was the engine?

Update: took it in and they found a bad idler pulley. Blamed it for the source of the noise. I still hear the ac compressor albeit a little less now.
