Debris blowing out through floor vents

[kramersfolly]

Greetings; for some weeks now I've had debris blowing up through the floor vents in our house. It began as small, very thin foil fragments and has now progressed to foil and find, brown dirt. It's very strong in a number of vents.

I'm guessing there is a damage in the ductwork and with floor vents, this means under the house, correct? I really know very little at this point beyond the basics, and I have no idea how to find the source of the debris. It's getting pretty bad!

Any ideas, help, advice, tips etc are most welcome.

My suggestion is to get a reputable HVAC tech out to diagnose this situation.

You might have some critters chewing up the insulation around the pipes...
