“Duct tape” is not to be used on ductwork as it is not designed for handling temperature extremes. The term was developed because the term “duck tape” which came from a strong adhesive back on cotton duck was trademarked by one company. Note that this company uses its trademark on several different backed tapes.
What you need for the ductwork is called HVAC tape.
There is also gaffers’ tape, available from dealers in photo and video equipment that holds lights and accessories in place and does not generally take the wallpaper or paint with it when removed.
What I use for general repairs I get at either the US Cavalry Store or Cheaper Than Dirt depending on who has the better price point that month. It is described as 60 mph or something like that and I call it military stuff. It does pull wallpaper, paint, finish or veneer off the wall. It holds—that is the general idea.
A note: In scout leader training we ran a lashing contest and prohibited tape. In a survival situation, use the tape.
