Re: changing cooktop vent from recirc to exterior vent
Does the wall the stove is on meet an exterior wall?
If so, you may be able to run the duct vertically above the cabinets and along the wall to the exterior. You'll need to create a soffit by boxing in the vent -- you'll lose any storage space above the cabinets.
A soffit really doesn't look that bad. Those decorative plates the lady of the house has up there just gather grease and dust anyway.
