a/c lineset vibration & noise

[bradarch]

On a fairly new a/c installation (1 year) there is a vibration and sound that is transfering from the a/c compressor to about the first 12 feet of copper line set.
Is there a way to limit this sound without re-working the whole line set and having to recharge the system? The suction line is insulated and the contractor mortered the opening where lineset passes through the masonry foundation wall.
Thank you

You could try adding weight to the copper line to reduce the diplacement or lower resonant frequency.
