98 civic blowing dirt?

Greetings all. 1998 Honda Civic Lx 150k. I got this car with no working ac so I put in a used compressor (I know that junk parts are no good but it was close to free). I filled up with the compressor oil then with refrigerant. The problem is that when I turn on the ac dust or dirt particles blow out of the vent. Usually this happens the first time you put on an ac after it sits for a while but this happens every time I put it on. The ac didn't work last summer (previous owner is a friend) and the old compressor that I took off was siezed and couldn't be turned (also snapped belt). Is this dirt a)-because of new compressor b)-some other bad ac component c)-normal d)- I've been breathing in too much r134a gas
The ac seems to be working it's not blowing COLD air but its blowing cooler air than the outside heat. Any advice on this topic would be great thanks

The stuff coming out of the vents is deteriorating foam from the ducting seals. Not much you can do about it. the stuff just rots away.

thanks for the quick reply. Would that explain why I smell the ac gas when the ac is on, or why it's only partially cool? I don't know why the first compressor froze up or broke and there's very little info out there on these systems because of this freon gas business. I replaced it with a cheap used one because it was a quick fix to change the compressor, clutch and the 2 small pieces that attach to the compressor (thermal protector and safety valve). Is there any info out there on how to diagnose the system a-z? Presumably if it's not fully cold with a full charge and I smell ac gas in the cabin some other component is bad and probably caused the first compressor to break in the first place. Any further advice or direction would be great, thanks

I don't think you are smelling the gas but the dirt or something in the refrigerant (oil or dye) IF the EVAPORATOR is the leak. Leaks underhood you wouldn't really smell easily. If it leaked that fast it wouldn't blow any bit of cool at you in a day and would be done working by now,

If you had a compressor lock up and all you did is put a used one one, you can pretty much expect the whole thing to happen again real soon. Every time one of these compressors lets go, it sends metal and debri all through the system which just leads to quicker failure of the second compressor, not to mention the cause iof the original compressor failure that you have not found or resolved as yet. The reason there is no info out there is because it requires a good understanding of how the system works and a well thought out diagnosis of what the issues are with the system.
