I would not acquire no for an answer, and located a way to incorporate a twelve"x12" return by harvesting the upper shelf of a wall cupboard to find the duct within the upper attic for the side attic in which the air handler is finding. This all remaining carried out soon after I'd a type of utility-subsidized blower door and duct force tests, which uncovered that my air return was unsealed and broad open up into the joist cavities among my two flooring (I needed to army crawl within my partitions with precut plywood and Wonderful Things to rectify this issue).
