I have a 9" flex duct from my Central heating & air unit that has a fairly long run. It goes from one end of the house from my first floor attic to the upstairs attic then goes down through a wall cavity to my family room. It does not have as much (or enough pressure as all my other ducts. unfortunately due to space limitations, I cannot make it any bigger. In my upstairs attic, I can possibly reroute it somewhat to take maybe 2-3 bends out of it & I am wondering if would really be worth it to increase the pressure at the register ? Right now I think I have 4-5 bends & I could probably get it down to 3-4. Any thoughts ?

Yes, I agree unfortunately I do not think it was possible to get a bigger duct through the areas that it had to be routed. The house is almost 70 years old & the CH & A was added about 15 years ago so I think this is all they had to work with. The ducting is not rigid sheet metal duct but the insulated flexible ducting. Initially I was contemplating a pusher fan & installing it in line about mid way but closer to the end of the run however I wanted to have it activate when the fan blower kicks on & not manually with a switch. The only problem with that is that I have a split system with a mechanical damper that divides the two zones. I wonder if the inline fan would come on everytime the heater blower does even if that zone is not heating or cooling ?

Still, what do you think about removing a couple bends in the run if possible ? Worthwhile ??
