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.

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

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:

You have a right to your opinion. A sig is ok in any NG & when a link
within the post is helpful & on topic I welcome them.
I don't have to defend my credibility, all I want to do is help people
live a better life. This is an NG that is supposed to be helpful to its
readers.
I will continue to communicate what is hopefully helpful irrespective of
opposing opinions. Live & let live. :-)
