I hope someone can point me in the right direction. I've got an airflow problem on the second floor of my house. Here is a picture of how it gets distributed:
There are 7 vents that feed from the square duct using the soft duct stuff. I was thinking if I swapped out the soft duct for hard duct, and did something about the extra foot of duct that feeds the branches I would have better airflow.
Any thoughts? I really appriciate the help, especially since it's been about 100 degrees and humid in VA!
