Charlie: James is listening to us on the stream up in Columbia, South Carolina.
Charlie: He says, “Should there be ductwork behind the return vent of a house?”
Tom: Well, air returns can be ducted, or they can be chase, what we call chaseways where you just build an area in the wall system where it’s just an open chase, and then it’ll go into the return plenum. So, it depends how it’s designed.
Charlie: Okay. But, the answer is not necessarily.
Tom: Not necessarily, but you just wanna make sure it’s all tight, and cleaned for sure.
