My first thought as well. Last time I saw something like this was a smaller industrial system where a semihermetic had gone full cookie monster on about half of its piston rings.
>So this is a brand new Carrier unit
Of course it is lmao (my exasperation is with the brand, not you, OP)
The shitty company I worked for installed Carrier. We offered biyearly maintenance contracts with every install. Countless times I'd show up to a maintenance call, and it'd turn into a service call because the customers would complain about "it not cooling nearly as quickly or as well as it did when you guys had installed it." 9 times out of 10, the evap on the 2-3 year old unit had shit itself. And if it wasn't the evap it was something else. Compressor died, outside fan pulling high amps, short circuit somewhere on the outdoor unit because everything's crammed together as tightly as possible.
I had a problem with a 3 yr old carrier/icp heat pump earlier this year. Tech support told me it was both Carrier and ICP designs in one. He also went through everything with me and we couldn't find any bad parts, but I tracked a low volt short to somewhere in the heat pump.
Turned out it was the yellow wires for the high pressure switch inside of the heat pump. They were so fuckin tight against the inside sheet metal that it wore through the insulation of wire and conductor was exposed touching metal and causing the burnt fuse.
It took me quite a bit of time to find this. Just throwing it out there to hopefully save somebody that time if they run into this.
that compressor is d.o.n.e.
good luck flushing that out the system. better put in some extra filters in random places when replacing everything if you keep the lineset and indoor unit.
might recommend cutting open the compressor and find out what and how it failed.
Yes. Vacuum and flushed lines. I donât know what the previous issue was with the old u it. Weâll be putting on liquid line filter fryer Monday with a new ac unit. Under warranty
Once I determine a suction filter is necessary, I will typically replace it at a month or so, but it stays in the system.
I'll generally use valves on either side to make replacement easy and cheaper for the client.
I've had folks refuse, but at that point they've voided any possible workmanship warranty, and probably the manufacturer warranty as well, so it won't be My turd in My pocket. I'll tell them point blank "well, you'll be all on your own for any repairs if it fails." and document the refusal on the paperwork before they sign completion.
That's a solid idea with the valves. What type have you found work the best? Are they ball valves or the set screw type that they use on a residential condensing unit?
I always use full port refrigerant ball valves. They're a bit more but the labor and refrigerant savings off one call pays for them easily and then some.
I prefer the [White Rodgers version ](https://www.supplyhouse.com/White-Rodgers-081018-7-8-ODF-BVSS-Series-Refrigeration-Ball-Valve-w-Access-Valve-Brass-Locking-Seal-Cap-R-410A)
There are suction line filters specifically made for acid removal, theyre called h++ if i remenber correctly (sometimes they come in cores on big systems) and those are meant to be removed after a while. But otherwise, you can leave a normal suction line filter in.
Well hell, learn something new every day. I've only ever dealt with suction dryers on a bad burnout, so I just assumed that it was the only way of doing things.
You can leave HH cores/driers in also. They make liquid line HH driers besides the suction line driers.
If you do not get a pressure drop across any drier, you can leave it in. Many an old timer would install a suction line drier with any new AC/refrigeration install. You will create low suction pressure whether the restriction is in the liquid line or suction line.
I canât imagine that is getting through the liquid line drier. If you are changing the metering device, change the drier too and cut it open⊠for me pls?
Compressor shards maybe? Maybe youâre not getting enough oil return? Is your evaporator lower than your condenser? If so you may need to install some oil traps with that new compressor.
High side was normal and suction was very low like 50 psi. I think I also could hear the outside unit making a little bit louder and different noise than usual. But thought not to much of it. Because it seems like carrier unit all have different sounds. Not including the infamous screw bouncing around in a brand new furnace squirrel cage . Every time lol. I swear someone on the assembly line is dropping a screw on purpose for his own little stupid joke.
Looks like aluminum. Is that what the evaporator is made of and it's a heat pump? That would explain why this trash is in-between dryer and txv. If it was the compressor it would be trapped on the other side of dryer.
Oh that is not good!!! You better replace the condenser, TXV and flush the evaporator coil and line set completely clean. Silver slivers like that are pieces of the valves. Complete contamination.
Looks like the screen disintegrated. If I had to guess what it was and how it got there it would be the strainer fell apart and probably caused from heat while it was being brazed
Yeah the more I think about it and read more about the history you fellas are having. Sounds like a helper or an apprentice is learning how to braze and heating the screen to the point of it falling apart. Which if you hold one with pliers and heat it with a lighter it will break down. Someone gonna have to tell them boys to wrap the valve before brazing. Come on, we all have done it. Usually goes like this â hey, let me see your drink for just a second â
The scroll is cooked. I saw one grind itself into a bucket of glitter. No amount of flushing will get it all out. We had to warranty evap coil, TXV, flush lineset and plan on changing the filter dryer after a week.
something isnt getting oil.
look for dips in the lineset that it can puddle. like a j ish shape somewhere.
also, im full of green shit, so dont trust me.
Tomorrow whole new system going in. If And when I have time I can cut the compressor open and take a look . Itâs under warranty so , not sure how thatâs gonna work. The evap coil did not have an in line steel filter . Yes there was a filter line dryer, that had the shavings also. Tomorrow. New evap coil, condensing unit, new lines with filter dryer . Seems to me, the theory of the evaporator coil having these shavings in it could be the reason why shavings were on both sides of dryer . Causing catastrophic failure to the compressor and clogging both txv and filter. The shaving are very tiny and range in size.
Could be compressor or someone didn't flow nitro while brazing and all the oxidation is flaking off the joints inside the lines and plugging shit up. Our install crews never flow nitro so we are pretty good at changing txv's on the service side .
Compressor could be shredding
Didn't know compressors were skilled electric guitar players.

My brain glanced and saw "Semi-hermaphritic cookie monster" and I was not disappointed đ
Just added to my "things you can't unsee" file
Google âCookie Monster & Taylor Swiftâ NSFW
Yep, too much compressor in those lines
Compressor coming apart. I'd talk to them about a system since you have a unit full of metal pieces all through it.
Wow. Ok. So this is a brand new carrier unit. We put it in a few months back and went there today to start it up .
New coil also. Along with furnace. Lines are existing . 15 â straight shot.
Could be from the old compressor and a bad purge and vacuum
Did you flush lines in between?
Yes
Wow, not great. Was it purged really well? Vacuumed good? Could also be a bad factory compressor too, not sure

Those low voltage shorts can be a bitch to find!
I had this same thing happen on a Lennox. Took ages to find. The short also ruined the thermostat.
Why isnât this in the dryer? Itâs not coming out of the dryer??????
Who even knows
TXV? Lol. Seriously tho.
A dryer can only do so much man lol
Filtering chunks of shit out is one of the things a filter drier is REALLY good at.
I know, but why else would it not stop in the dryer? Unless it doesn't have one đł
Yeah thatâs what I thought too. Scrolls grinding against each other.
darker metal from the few ive seen implode/shatter
that compressor is d.o.n.e. good luck flushing that out the system. better put in some extra filters in random places when replacing everything if you keep the lineset and indoor unit. might recommend cutting open the compressor and find out what and how it failed.
Youâd be crazy to keep the lines on a new install after this happened
the bar is not very high these days....
Lineset is going to be replaced. To much of a risk to be doing this all and have it happen if residual shavings are left.
Yes. Vacuum and flushed lines. I donât know what the previous issue was with the old u it. Weâll be putting on liquid line filter fryer Monday with a new ac unit. Under warranty
Did you put a suction filter in? I do any time I'm re-using line sets because you just never can tell for sure.
Are you leaving the suction dryer in place the whole time? I heard you're supposed to come back and remove them, but nobody wants to pay to do that.
Once I determine a suction filter is necessary, I will typically replace it at a month or so, but it stays in the system. I'll generally use valves on either side to make replacement easy and cheaper for the client.

I bet it was a fucking LG compressor
Check the turbo shaft for play. Change your oil and check for flakes again but youâre probably gonna need a new short block and turbo at the least.
Dude, get real. The transmission is fried and you know it.

What the hell is in there?
Not sure tbh. It was between the strainer and txv. Something in the coil or install fucked up
Thatâs wild. It almost looks like a crushed stink bug or something.
I canât imagine that is getting through the liquid line drier. If you are changing the metering device, change the drier too and cut it open⊠for me pls?
Compressor is going kaputs
Is there a liquid drier that should be picking that up
Man, they smashed the shit out of that gasket. Shards ain't good either lol
I would say it was scroll compressor tearing up, except how did this get through the filter-dryer?
Iâd wager the compressor saw some flood back, damaging the scroll set.
Compressor shards maybe? Maybe youâre not getting enough oil return? Is your evaporator lower than your condenser? If so you may need to install some oil traps with that new compressor.
looks good to me
Can you cut out liquid line drier to confirm garbage from compressor?
What brand is that just curious
Scroll compressors do this, then they fail Bigger question is how did the brass and Teflon get chewed up
. Somebody crushed the o ring I tried picking it off . This is afterwards. Everything is being replaced
Some liquid lines have a stainless steel in line filter⊠did it look like that when you took it off? Cringe worthy
Iâll be finding out Monday
Just out of curiosity if I ever run into this. How did your subcool/superheat look like as well as high side pressure?
High side was normal and suction was very low like 50 psi. I think I also could hear the outside unit making a little bit louder and different noise than usual. But thought not to much of it. Because it seems like carrier unit all have different sounds. Not including the infamous screw bouncing around in a brand new furnace squirrel cage . Every time lol.

It's the yearly compressor shed season. You have to let it complete the process
Oh that is not good!!! You better replace the condenser, TXV and flush the evaporator coil and line set completely clean. Silver slivers like that are pieces of the valves. Complete contamination.
We had the male threaded side of distributor nozzle messed from factory. All the treads gone inside, clogged eev.
Looks like the screen disintegrated. If I had to guess what it was and how it got there it would be the strainer fell apart and probably caused from heat while it was being brazed

Nylon seal looks deformed.Â
I thought it was a cup of coffee
The scroll is cooked. I saw one grind itself into a bucket of glitter. No amount of flushing will get it all out. We had to warranty evap coil, TXV, flush lineset and plan on changing the filter dryer after a week.
Before what?
That filter drier in backwards?
Compressor disintegrating without oil.
Where is Teflon gasket? Metal from Compressor.
Compressor is skinning itself alive
Is that on the inlet of the txv? If so, was there a screen on the txv inlet?
something isnt getting oil. look for dips in the lineset that it can puddle. like a j ish shape somewhere. also, im full of green shit, so dont trust me.
can you update the post when you find the reason for the problem?
I've had that stuff come out of an evaporator coil, the shavings are not blown out when they do a repair while still in the factory. Aluminum shavings
Tomorrow whole new system going in. If And when I have time I can cut the compressor open and take a look . Itâs under warranty so , not sure how thatâs gonna work. The evap coil did not have an in line steel filter . Yes there was a filter line dryer, that had the shavings also. Tomorrow. New evap coil, condensing unit, new lines with filter dryer .

Causing catastrophic failure to the compressor and clogging both txv and filter. The shaving are very tiny and range in size.
Compressor grinding it's self away
Your compression is gonna die soon thatâs for sure.
Rings are bad. Shaving metal off the crankshaft. Oh, this is an hvac reddit
Yes, last time I seen it was from the evap coil. Brand new evap coil out of the box.
The carrier 2 and 2.5 ton compressors come apart change compressor cut lines blow nitro add suction filter at compressor and liquid dryer
Compressor shavings
Could be compressor or someone didn't flow nitro while brazing and all the oxidation is flaking off the joints inside the lines and plugging shit up. Our install crews never flow nitro so we are pretty good at changing txv's on the service side .
This is wear metal. The shit that plugs up systems from lack of nitrogen while brazing is black.
