BTW - they do make mushroom shaped units that don't project outwards much.
P-Gal must first find out what the local code requires and they are not always uniform across the US.

Randy,
It is the huge volume of air going through a narrow space, like a standard 6 inch duct in must homes, that makes the most noise. Like a jet engine. Its isn't just installing a big motor that pull lots of air. It will work better then a little motor, but noise level will increase. Most dirty contractors don't understand this, or they don't care. When its done, you have a very loud vent system every time you cook.
Most residential remote mounted units aren't that big unlike commercial one that are belt driven.
