Vibration in Refrigerant Piping

A good way to tackle this problem is always informing the customer in writing and quoting a lower noise unit and a normal one and let him choose.

This takes a lot from your shoulders but the legal aspect depends on local laws and rules.

Yes people tend to get intolerant if you rub them the wrong way as I’ve come to learn … from these posts too, I seem to do that a lot!

You were right to mention the fan noise it is an important issue, you can lower it with slower fans but probably need larger condensers, and be careful when installing them in windy areas because you normally don’t consider wind force but you must with slow fans.
