Whine/drone sound when AC turned on.

After several replacement compressors (under warrenty) there is a huge whine/drone sound coming up thru the steering column which can be felt on the steering wheel from idle to around 2000rpm. The video above was taken today.

Anyone have any ideas of what could be causing this issue?

As soon as you turn the AC off, the noise stops almost immediately (2-3 seconds).

Thanks.

Engine mounts is one thing, another is a pipe touching where it should not.
