I need to close off a flexible AC line. I combined two rooms by knocking the wall between them down, and the room is small enough that one register is plenty. I’m having subfloor redone so I can remove the extra register as well. To close off the flex line, do I just need to cut it and seal it as tightly as possible with tape?
More permanently, I’ll try to remove the line entirely, but for a temp fix until I’m able to do that, would this work, or is there a better fix?

You could just use a cap of the proper diameter for the flex to seal it (using tape and panduit strap). Best way would be to pull the flex out and seal the hole in the ductwork with a sheet metal patch.
