Furnace problems....

[Matthew Reed]

Not sure what to do. Got this house to refirb and found that someone has taken the original furnace - a down-draft that blew into the ducts in the crawl-space - and changed it to an updraft. The updraft now blows into some new ducts in the attic and uses the crawl-space ducts as the air inlet. The ceiling ducts are not installed correctly, don't have the correct placement and are leaking like crazy into the attic. Some are needed for an addition that is on a slab.

The crawl-space ducts are rusted and need replacement.

What do I do? My partner says "fix the leaks and leave it". I think we should replace the updraft with a downdraft and have it working right. But that will be $$$.

Any suggestions?
