Thread: Rusty ground air ducts

We are selling our home and noticed that some of our ducts are rusted. Will we have to re-route the ducts through the ceiling to get it to pass inspection or is there another inexpensive fix to this issue? Thanks!

DH: Where are they located, in the attic or a crawl space? How badly are they rusted? Do they have holes in them? Pictures?

More likely than not, yes the ducts will need to be re-routed.

... or is there another inexpensive fix to this issue? Thanks!

More likely than not, no there is not an inexpensive fix for this ... well, depends on what you consider "expensive" and "inexpensive" I guess.

First, though, Aaron's questions about access and the duct's locations need to be addressed.

I will take pictures and will try to post asap. The ducts are in the foundation. I have no crawl space. I'm pretty sure that some have holes where rust has rusted through. I've heard that I could "patch them" but not sure how or if this would pass inspection if I did so. Thanks!

That's what I was presuming with my answer.

The old ducts in the slab trick huh. Isn't that how a family died when a pest control guy drilled down and treated for termites but actually loaded the ducts up .

Bad story. I never did find the write up on that but it did happen.

I've heard of that too. Yes, I believe it really did happen.
