Hi all,
I've got a Sears Kenmore room air conditioner unit in a thru-the-wall
sleeve in my living room.

When it's running, it keeps spitting out little pieces of
black--something--perhaps dirt, that are really dirtying up my nice
carpet. Not all the time, but maybe a half dozen chunks each day.

I cleaned the A/C filter, but that's not stopping the problem.

Where is that black stuff coming from, and how can I stop it?

Disintegrating insulation? Gasket?

I used to work in a building where the central air spewed black soot. We
made them tape filters on top of the vents. They practically tore apart he
building for ten years trying to figure out what it was. After I was long
gone, they figured it out. Turned out the grabage trucks used to pull up
right by the intake and spewed exhausts into the building HVAC. THis was a
building chock full of world class engineers!

Probably a dried out foam gasket. I have an older car that is doing
the same thing. Brown sticky pieces of foam come out of the vents
sometimes.

My old unit had a sponge rubber filter right under the front vents that
dried out and began to crumble after a few years. It was pretty worthless
to start with. While it did catch some dust, it was hardly enough to keep
the cooling fins from getting pretty gunked up so I tossed it.

What does the black stuff look and feel like? Could be pieces of the foam
filter, but can also be wads of mold that built up in there over the winter.

He never said he had a foam filter.

This is probably fungus/mould growing on the wet evaporator. It will
need to be cleaned and sterilised with a suitable chemical. Not an
easy job.

So what? It may or may not have one. Maybe it did and it was replaced. It
is still a possibility and I'm sure he is capable of looking as to the type
of filter he does have.

That's what it feels like as it crumbles away between my fingers.

I had better get that cleaned soon, I have terrible allergies.

That's the problem with renting because you're at the mercy of your slumlord.

If you owned the window AC, you could take the unit apart and clean the coils as needed.

Â* More likelya buildup ofmold and dust/condensate mud . A good start
would be to pull the front cover and clean or replace the filter and
vacuum as much crud as you can from the evap coil (that's the one right
behind the filter) . You can break that crud loose with an old
toothbrush as you suck it outta there . Spray the coil until wet with a
household general purpose cleaner with bleach to help kill off the mold
.. What it probably really needs is to be pulled and completely cleaned .
BTW , that mold in there can be a breathing hazard for some people ...

We'll have to rely on the OP to let us which they more closely
resemble. Good guess. On a cold night, an air duct might be good
place for a mouse to warm up. I didn't think of that..

My units from the 1990s started doing that a few years ago. Blowing sheet-like
chunks of smearable stuff that has no mold odor to it, as well as finer
particles. I'm sure its not mold (I hope) because I am allergic to mold and I
always feel better - breathe better - with the units running. I took the front
off - the face bringing the grill mount with it - and cleaned what I can get
to, but it makes no difference in the debris production, especially at first
use after the heating season. I clean the dust filters once a week when I'm
running the units. They sit in the windows over the winter as I can't heft
them out anymore and have no place to put them if I could. They work well - my
hunch they are better than anything I could replace them with. One is made in
the US and the other in Japan.

Same issue here. I have a living room 30year old GE thru-wall-unit made in Japan that still works! Came with my condo and for the past 3 summers it has spit pepper size black particles onto the floor that are soft and easily smear when I clean them almost daily. I took out this very heavy until in 2019 and throughly cleaned it with paper towels and vacuum and it was disgustingly dirty and rusty. Less particles spit out but it did not stop. I live in Chicago area so I cover the until both inside and outside to stop the cold air from coming in so I'm wondering if this would build mold, however my bedroom a/c does not have this problem. I really miss the mini-split a/c units we had in Europe, seemed cleaner and more efficient system. I'm thinking of purchasing a new unit this summer as as I jokingly googled it but seems I'm not crazy now but even more disturbed. Cancer survivor here so its scary to think it could be mold. Good luck to you all in resolving this issue!

Sounds like mold. I'd get the coil and fan professionally cleaned
outside of the house.

I.ve seen that before - but the rubber was not only rotted but slimy
- with mold or something very mold-like that came off with bleach -
bleach does not take off rubber - - - I cleaned it up and used some
weatherstrip foam tape to replace the "seals" then sold it.

Spraying through the front grill is probably not doing a very good job.
You have to take it out of the case so you can flood the coil and
possible the drain pan. Best done outside so you can rinse it well.

Ed probably knows more about this, but I woudl have thought it was the
foam filter coming apart. OTOH, if it s 4tarted in the 2nd year,
another reason to think Ed is right.

I myself would not bother a landlord about little things like this
(unless nothing fixed it and I couldn't use the AC), or expect him to
pay the $10. It was partly this behaviour (never calling him) with my
landlord of 6 or more years, partly that I didn't call him at home and
certainly not at night, that even though I went on personal rent strike
twice and he had to take me to court both times, and even though it was
a draw once and I won iirc $150 one of those time, he was still willing
when he was paying me to leave to pay me before I actually left. So
that his assistent, who often handled things in court, told him not to
pay me before I'd left, and the landlord's reply to that was "You can
trust Micky."

For various reasons, I thought he was a jerk (and that's the nicest word
I can think of), but I treated him politely anyhow.
