I recently inspected a townhouse and ran across an interesting situation. The forced air furnace is located upstairs and is a downflow type. What I discovered is that there are no return air vents located downstairs at all.
The furnace is located in a closet/laundry room upstairs. The only return air intake is located directly on the other side of the wall from the furnace. The return air enters directly into the plenum through a vent installed on the other side of the wall. A filter was installed in this area and it was completely filthy (causing all sorts of other problems)
I am no mechanical expert, please advise if there is a requirement for return air ducts installed throughout the dwelling.
