Based on what? I'm going to have to see some info to support that, many
higher efficiency units have variable speed blowers that ramp to speed,
reducing blower noise etc. Just don't install a Lennox Pulse if you're
concerned with noise, we're not talking Atta-Boy's here! ;-)

Based on surmise. You are just considering loudness. I
would expect the more efficient furnaces to run the blower
more of the time, especially if they use multiple blower
speeds.

And you would be correct. Most often, the blower may be set to run
continuous at about 1/2 capacity allowing moe even comfort.

Just because the blower doesn't run at full speed
doesn't mean the blower noise isn't irritating and that
could be considered more noise, or noise more of the time.

True, but if the ductwork is sized and installed properly - *TaDa* quiet.

I prefer a house to be dead quiet but it seledom is due to
the computer and refrigerator, let alone the furnace.

See above ductwork reference and take unit location into account when
building. I understood your reference to indicate that you were advising
the higher efficiency to be likely louder than the OP's almost new std. eff.
That's just not normally the case, IMHO. Oh, and turn on a bit of music,
it'll cover up that fridge & computer. ;-)

Maybe you are thinking of furnaces out in the garage, but
ours is in the center of the house it an enclosure, hate to
call it a closet. No way is it quiet, or would be quiet
regardless of type.
Hell, I can hear the hum of the attic fan in certain parts
of the house. Music helps but I grew learning to read and
study when it was quiet so I'm likely to start listening to
the music instead of paying attention to what I am reading.
Nothing like reading 2-3 pages then suddenly realize you
were listening to the music and have no idea what the word
in book were.
