Missing Second Floor HVAC Return….
Recently I inspected a brand new home and as I looked at the HVAC system I was amazed to find that the Builder had installed the interior air handler in a first floor utility closet. For returns he installed open return grates in the side wall of the closet in the living room and adjoining first floor bedroom. The unit was open on top in the closet. Problem is he failed to provide for returns on the second floor. He provided supply vents in each of the second floor rooms but no way for the air to recirculate. In this situation there is no way to effectively condition the air on the second floor, in the summer it will always be hot and in the winter it will always be cold. The rule is always have at least one return on each floor so that the air can be drawn into the system heated or cooled and distruted back into that area.
