I have checked temps comming from the registers in two locations (two different bedrooms). The difference is 8 degrees!
Checked for leaks either end - no luck there.
Changed both ducts with new 6.0 r value runs. same diameter same lengths, no bends or separate attic areas.
I do not know what is causing one to be 8 degrees lower than the other!
Any help would help.
:confused:
