I am just having a new plenum made and a transition to my old supply duct all insulated.
I pick it up later today. I was quoted for about $300 not to bad.
So far I am glad I am doing his part myself.
This is my current plenum I am just replacing this.
The new plenum is 34" 1/4 by 18" 1/4
The old supply. I am just getting a transition made to connect to this one to the Geo unit.
Geo Supply
Geo return.
