I'm going to add some crown moulding to some bedrooms. I've got HVAC vents mounted near the top of the wall and the moulding will cover part of the vent.
I want to move the vents out of the way. I can't move them down and am thinking of moving them to the ceilings instead (there's an attic above them so I've got reasonable access). Is there any reason this is a bad plan? Do they work just as well in either location?
