I have put in a new wood furnace in my basement and now need to hook my new ductwork from it to the existing ductwork. My question is about pushing hot air up through the coil for the existing AC unit. Can I just fabricate a piece of metal that will fit right on top of the coil? There is a perfect spot for this if it will work. Or will the heat damage the coil? I know they make backdraft dampers but even they would let heat to the coil on the A/C right? Can I get away with just a backdraft damber on the woodfurnace side?
Thanks.
Thanks.
