Flexible duct in soffit


I bit the bullet and cut a hole into the soffit in my kitchen. Stuck my head in there and took a look around, and found wires to the light over the sink and about two feet of flexible duct. It's extended from a metal duct in the outside wall and terminates in the register vent upstairs in my son's bedroom floor. The register sits directly under the window in the bedroom.

I'm wondering why the duct just doesn't go straight up. I understand not punching through a load-bearing joist, but why not just extend the flexible from it and up through the floor? It would be a foot farther away from the current register.

In another bedroom, the register is right next to the closet door, not really near the window at all.

Just wondering about the configuration and if I can move the vent to remove some (or all!) of the soffit. Thanks!

The register doesn't have to be at the window, so yes you can move it.

Flexible duct in soffit


We've completely demo'd the soffit. It looks like the only reason the original vent wasn't continued through the wall and up into the ceiling is because of the ledger board that belonged to the soffit. (On one side of the soffit, the builders cut through the ledger board to make room for our main drain line.)

Is it really as simple as just removing the ledger board and linking up a short run of rigid vent? I figure we can trash the flexible duct because we won't be re-routing anything.

This is the flexible duct branching off from the duct in the wall:



This is the flexible duct wiggling up to the air vent in the bedroom over the kitchen:



A different angle of the flexible duct branching off:



Thanks for your help!!!!

Geez, no wonder your air flow to that room isn't very good.

Yes, you can cut out that ledger board and run the duct up. Should wrap it with insulation though.

I know, right?!?!?!? Heading off to Orange or Blue to pick up supplies today. Shouldn't be very hard. I'll get a better look at the set-up when I rip out the flexible duct. I'd bet the duct in the wall is wrapped in insulation, anyway. I'll just follow. THANKS!!!!!
