Default Weathermaker 8000 was extremely loud, now whisper quiet

Ok, so I have a Carrier Weathermaker 800 in my house that was rattling and
running so loud that we couldn't hear anything. We had a guy come check it out
and at first he said something was probably stuck, but couldn't find anything.
Then he said we needed a new blower motor and wheel.

So today, it is whisper quiet and and working better than ever before. And I'm
thoroughly confused. No work has been done. Any ideas?

Sounds like you had a very good tech. The furnace just KNEW it had to
shape up. I sometimes have that effect on equipment. I get close and
whatever was malfunctioning mysteriously stops (for at least as long
as I'm around - but often longer)

More than one of my clients has joked about having a picture of me
around for when I'm gone on holidays - - -

Could be a bearing/bushing is on its way out and the "wheel"
happened to have been moved onto a sweeter spot -- for the
time being.

Thanks for the replies.

So should I go ahead with the replacement? Or save the $700 for the time
being.. I mean seriously, it's never worked better since we bought this house..

Look at the bearing/bushing. Move the "wheel" off to one "side",
try it; move it to the other side, try it. If there's slop or
a noticeable difference in performance, inspect more closely and
see if you can just replace the bearing/bushing.

You may find that it sounds good *now*. But, over time, the
wheel "moves" into a bad spot that makes the noise more
pronounced. I'm just suggesting you do that NOW, manually,
and see if such a spot exists; then figure out WHY it exists!

E.g., swamp coolers (here) have a large squirrel cage blower...
like 2 ft in diameter by 1 ft wide. They tend to be supported by
sintered bronze bushings that wear, over time. Replacing the
entire squirrel cage would cost more than the cooler itself!

OTOH, swapping out the bushings is an hour's work and $30...

I would put the money aside for the repair and see what happens. It
may go another 5 years with no problems or it may get loud in 15
minutes.

If and when you have the repairs done, have them done by the company
who told you it was the problem and get a warranty - not just on the
repairs, but on solving the problem. If what they replaced doesn't
solve the problem, they make good on it.

My guess it was something stuck or out of line and while he did not see
it, he fixed it. His poking around could have knocked something loose
that fell out or stopped something from rubbing. Could even have been
the access panel.

My seconf guess is he did not have a clue what was really wrong and
figured replacing everything would fix it. Motors do go bad but blower
wheels rarely have problems unless physically damaged.

I;d enjoy the quiet and do nothing until something happens again. Ten
I'd call a different service compamy.

I wouldn't be surprised if there was just something rubbing the fan that got
moved during the inspection. Just keep ear on it.

I'm curious Mr.ZM, was the noise inside or outdoors? O_o

If this is like the typical furnace blower, you'd think the bearing is part
of what was replaced just a year ago, no? And if it's like a typical blower
and you have the typical repair tech, they aren't going to replace a bearing,
they will most likely replace the whole motor or blower assembly, etc.
A bearing like that isn't typically even shown on the parts diagram as a
separate, replaceable part. If you're creative, capable and determined,
as a DIY you may be able to identify it and replace it.
