my new 15,500 units are a bit louder than the carriers they replaced, but it has been softened a bit with foam and ensuring everything that can wiggle is supported with cushion clamps
and i have done like others and tried to make the intake air route is as smooth as possible
right now on high fan about 4 feet away it reads 55 db, at the intake it reads 63
that falls in the CONVERSATION range??
the rumbly noises i softened with a few screws in the outside cover that was flapping around.
