Aircon/heatings sounds like a tractor

[Rholtby]

Evening all,
I had my aircon serviced a while back, they told me then it was faulty. I've scanned the car with carista. I may need to scan it again as I've lost the report but I believe one of them was a faulty compressor. Would this cause the heating to vibrate through the car sounding like a tractor?

One way to check is to remove the serpentine belt and see if the problem persists.  It only runs the alternator and compressor, so don't run it for too long!
