Are those flues on the right of the pic #2? I'd be a lot more concerned with their configuration and the paper insulation facing up close to the one.

Have a great one.

Copper & steel only corrode if there's a liquid electrolye present. I doubt it'd be much of an issue in my climate. Don't know about yours.

I've seen copper water pipes going through ducts many times on older houses but I've never seen a problem because of it.

Looks like a non-issue to me.

I see other stuff in those pictures though. . .

FWIW, my understanding is that, besides corrosion from dissimilar metals, other concerns can include leaks/condensation/mold inside the ducts, and "unplanned air exchange/leakage" in the ducts.
