Here are my thoughts, but I am no expert on this.
I would think of it like this:
1) The guy came out and gave you an opinion on what the problem is,
suggested a solution, and gave you a price. I don't know if he charged you
for that service, but from the way that you wrote this I am assuming that he
2) It couldn't hurt to get another opinion as to what the problem is and
what would be a good solution; plus get a price from the second opinion
person for whatever solution he suggests.
3) If it were me, I think that I would test the theory of the first person
by taking the vent cover off of the noisy return vent and seeing how the
system sounds with the vent cover off. If the 16x20 return duct is too
small and is causing a restriction in the return air flow which is causing
the noise, then the vent cover itself will be restricting the return air
flow even more. By taking the vent cover off and seeing if that changes the
noise situation, you could help confirm whether the first contractor's
theory is correct.
4) What is below the living room? Is it a basement with an open joist
ceiling, or a crawl space with an open joist ceiling, or what? Do you know
where the contractor is proposing to run the new return duct -- in between
the ceiling joists, or somewhere else?
5) Depending on where and in which direction the ceiling joists run, would
it be possible to create another return duct using the open ceiling joists
as a return duct with just a flat metal cover over those ceiling joists?
High or not that is his quote get another contractor. I see to many people
at TV court show's with similar
No one forcing you to take quote get some ales..

I had a HVAC contractor come over and evaluate the loud noise we get from
our vent in our living room (built in 05). He says the original contractor
under spec'd the size of all the return vents in the house causing us to
hear the blower through the vent (The 16x20 vent could suck a piece of
cardboard down it there is that much pressure).
His solution is to add another floor return vent across the living room. So
he will cut a hole in the main return line at the furnace and run a flexible
line about 12 feet and cut a hole in the floor and add a vent.
Quote is $1250. To me that seems somewhat high as I can't imagine the parts
will cost more than $250 and the job (to my mind) can't be more than 4
Should I get a second quote or does that quote seem rational?
