I have a centrl air unit installed in the attic; I was recently going duct by duct to make sure all connections were tight and insulated - during this process: I noted that the return duct which draws air from inside the house was insulated for the first few feet but then ran across the attic uninsulated until it went back into the unit. Am I mistaken or should the return that passes through the super heated air of the attic also be insulated? I spoke to a contractor friend of mine and he said it is common not to insulate the return - but it just seems wrong to me...
