An AC company came and added heat strips to my heat pump unit. They also
added two ducts. When I checked them, there is very little air coming out
of them. When checking the ducts that were in place, there's a good flow of
air from them. The new ducts are about 20' long on each leg. Could there
be too much resistance to push the air that far? I would think a little
bit, but there's hardly any air coming out.
I have called the company, but they can't send anyone out until Monday. I
went up in the attic, and can't find any place where the flexible ducting is
loose or not held together well with those bands.
Any ideas?
Steve

...
What about returns? If there's no return where these new legs go,
they're pushing against a dam...

I'm not so sure the new ones aren't returns

The above response is apt to be part of problem, there could also be
many other factors that need correcting.
There is a proper way to install ductwork.
The entire ductwork system should be evaluated for proper design &
function in accordance with the "Manual D."
Learn some of the fundamentals so you will know if the contractor is
doing it right:
