What noise? Do you mean air rushing out of the vents? The
blower coming on? Both? Other? Ass-u-me it's a forced air
system from your descrip.
Sending output to unused, unwanted places is, uhhhh, shall was
say, STUPID? I bet that guy's union would like to hear about
this, if you feel like the effort! And so especially would the
BBB and your local code enforcement office. Talk to the latter;
they may have some good advice for you, but you gave no hint of
where you're located or even urban/suburban/exurban/non-urban.
Too little information for anything definitive.
But, that is about the worst advice I've ever heard of coming
from a reliable and honest contractor. Something's not cricket,
either with your post or that contractor. I'd guess at this time
that you have more issues than this one because it's a LOT more
involved here than "extra" capacity.
You were very wise to consider the extra capacity, and it's a
very smart move that's cheaper today than later, but ...
something's very wrong here.
I suggest another post with more details.
