Furnace ducts replace

[hillboy]

Mice ate lots of holes in my furnace ducts. Getting the furnace out was easy but removing the part the ducts hook to was not. No doubt removal was not seen as necessary. I had to get in back to access and replace the ducts.

OK so I got that out and my question is are there newer type ducts that mice might not eat?
Can I convert to floor mounted ducts? The existing ones are wire flex sort of metalic material.
Any suggestions appreciated.

The best thing to go back with is the flex dust like it has. Unless you have lots of open room to work in, a rigid duct will be hard to install.

Thanks, Good advice.

Finished this project. Like most motorhome projects it grew a little.

All of the ducts, not just the mouse chewed ones, had holes. Most were small but all would leak air/heat.

I used a combo of rigid elboes and newer mylar coverd flex. Tied string to the old ones nad pulled them out. Then used the string to thread the new in, or out as the case may be.
This was with a surburban furnace so after removing the furnace from the shell I could access the snap rings for the ducts and do the hook up.

Like most deals the second time would be easy. The benefit is no air/heat loss now and removal of 20 years dust.
