Closing off air ducts

Wanda1885
10 years ago

I recently removed my oil furnace and installed a mini-split heating system and now have all the air ducts in the floors which I would like to close off. Any suggestions? I don't need them any longer and I seem to be getting the colder air rising from the basement where the oil furnace used to be so I want to close these off to avoid heat loss. What's the best way to do this? Any help would be greatly appreciated!
Thanks!
