My old 28 years old unit made half the noise and had no vibration.
Attic ac unit vibration.
Assuming this vibration noise occurs only when the a c is running which should be real easy to check out and you cannot find loose mounting bolts or loose metal ducting thgat is vibrating then you should not quit using the unit and call a heating and a c tech to check it out.
Buy four vibration pads one for each corner of the unit.
Switch off the power supply.
Climb up using a ladder and find the ac on the roof.

Measure and make a note of the width and length of the base of ac.
