Every space in my residence has one supply vent and one return vent. Exactly what I recently discovered when I was taking a look at my furnace is that the return-air ducts (which are actually stud tooth cavities with sheet metal at the bottom) cause nowhere. They get to the air filter, then the hole to the heater is obstructed. On the opposite side of the heater, there seems to be a much newer pipe linked for outside-air intake. My best guess is that at some time, the previous owners included an A/C system (which is newer) and at the same time set up the new air consumption pipe. Why on earth would they have done this? Does this mean that the filter, which is linked to the deserted return-air duct, is refraining anything?
