Want to reroute ducting....


I am redoing my laundry and find my current furnace ducting to be in the way. currently it runs directly out of the furnace down the center of my basement (basement is split in half into a den and laundry room). It is tight against the chimney and stops at the entrance to my laundry. This main trunk feeds the den and laundry. Unfortunately, the bulkhead for this trunk causes clearance issues. I would like to move it over to the exterior wall and then branch off from there. Any issues with doing this? Any tips? The laundry is exposed ceiling and the den is not exposed. the total distance from the exterior wall to where the ducts end is no more than 15'

The duct you add to move the trunk to the outside wall will need to be bigger then what you already have.
Or you won't get as much air as you do now.

The distance from the furnace to the exterior wall is about 6 feet.

The extra 90 ell at the wall to run parallel with the wall has about the same restriction of about 55' of duct.

Would the piece that comes off the furnace and the 90 bend be a larger size and then the rest of the duct reduce to the current size? I will check actual size tomorrow

The rst of the duct can then reduce to current size. You can use a reducing ell. Or a reducing thransition right after the ell.
