The roof of the building in which my studio is located has a condenser
that
is vibrating and sending an awful sound through my place. Can anyone
suggest
a method to decouple it from the roof to get rid of the vibration?

There are lots of companies that offer isolation products. Try
www.kineticsnoise.com

The most popular method I've seen is to build a steel hanging support for
the
unit and hang the unit with springs. My air handlers are inside the
building
and are all hung from the ceiling with springs. The compressors are on
the
ground outside on vibration isolators.

Wouldn't it be cheaper to fix whatever is out of balance?
