The installer working with the duct situation came up with a great plan.
The original plan was to extend the duct run along the joist space in the basement, notch out the joist closest to the south wall and run the duct up about 14″ closer to the door. When the contractor thought about this, he decided that wasn’t a good idea as the joist was already notched for the existing duct and had been structurally compromised.
They have cut the floor to prep for putting in the headers.
So what they are going to do today is put in a header of 2 x 2×8’s back to the next joist over and sit them into the brick exterior of the house. That will allow them to cut the joist and join it to the header giving them room to move the duct.
Also, the are running the duct in a straighter run in the basement eliminating some of the 5 or 6 bends which are currently there. No wonder that original duct doesn’t really do much to supply the office! Hardly any air is getting by all those bends! I am hoping that the new supply line will be much more efficient.
