The two ducts were way down there. and one in bath.
The other is on other side in master bedroom. None on couch fascia.
That t stat would never satisfy IMO in the winter..
Now I have a duct there.
Now that I have one there under couch I may add another. Since I have room for one more on the plenum. Ill put it about 3-6 inches from this one on the couch..
As far as intake air?????
IDK I assume it comes in from the big space behind the back of couch. There is a big gap there. They have this big piece of luan over the furnace.
The Air flow in I assume is the channel where I ran the new duct through and air gets drawn in from behind the back of couch.
Maybe I should remove the piece of luan?
