We have a 36" gas cooktop with a 36" GE range hood. The hood does a horrible job of clearing smoke and grease. We'd like to have someone put in the duct work to exhaust outside. Our range sits against an interior wall, but is only about 3 or 4 feet from an exterior wall. This shouldn't be that big of a project for the right contractor, right? This is a new construction, colonial home less than 2-years old. Who would we call? An HVAC guy, a kitchen guy, an electrician, a general contractor or what? Anything else we need to know? Thanks!
