Not a return
Popped off the louver and I see a foil hose that disappears down and to the left towards the closest wall. However, there's no exit point underneath and nothing on the exterior wall. Only place I haven't checked is the roof.
Also, there's no air movement while running the furnace. And, anyway, the furnace is 15' away with a huge kitchen slide-out in between.
I'll be calling Crossroads in the morning to see if they can identify it, but I'm 0 for 3 in getting answers from them on anything.
My wife noticed that there was a place labeled for a "vent fan" switch on the control panel for the garage. However, there's no switch there.
Anything I could be missing?
