plenum rebuild vs. replace

We are in inspection negotiation with a home that we want to purchase. Our inspector noted that the plenum has been in contact with the soil and the bottom has corroded away. The seller's repair agreement says that it will rebuild the plenum. We have no experience in home repairs, much less HVAC--is rebuild fine or should we ask them to replace it? We are waiting to hear back for clarification about the wording, but I would like to know ahead of time if rebuilding it is fine.

They are hiring a local heating and cooling company that has excellent reviews to do the repairs.

The replace will be rebuilding :thumbsup:

Now I'm even more confused.

"Rebuild" to me means they leave the original structure and replace just the corroded part.

"Replace" to me means that they will remove the original plenum and put in a new one.

But maybe "rebuild" means something different in this context that I'm missing?

Depends on the material that was used.

lol come on guys, give a straight answer, it is much more convenient to replace entire plenum because even if they do a VERY good job, you dont know if something in the plenum has died (i.e. mouse, rat, hippopotomus etc.) thus it will cause a stench and will cost you even MORE money to replace it if that is the case.

Nothing smells like a critter caught in the heat strips...

Rebuild or replace will depend on the material used to make the plenum. But more than likely it will be replaced. Its usually easier than trying to attach new material to old..
Now if the plenum runs for a long distance then just the damaged section would be replaced. Which is all that would be needed.
