I've heard that running AC wires through a heating/cooling duct is not allowed by code. I figured there are a number of reasons for this.
My house has some ducting for the central heating and air, and there are also a number of air shafts that just use the space in the wall between studs (no metal ducts). While inspecting the wiring in my own house (which has had 4 previous owners), I see some wire that goes into one of the air shafts. It doesn't go into any ducting, but it does go up the same stud-section that is used for the air shaft.
So I wanted to know, what are the specifics about running through air shafts or ducts? My guess is it isn't allowed in either case, but I wanted to find more info on it.
Thanks.
