Can I use duct tape?
Okay, I am supposing this is a silly question but I am going to ask anyway. If I am taping ducts do I use duct tape (as in Red Green, grey tape)? Somewhere in my head is the nagging thought that I am not supposed to but I don't know why. Also I have a whole Costco sized pack of duct tape so I would like to use it if I can.
Part B of this is that I live in a 76 yr old house (bought in May '06) with a new furnace, but older duct work. When they installed my cable they came through the floor vent and a bunch of duct work fell. So I need to hook it up again as winter is closing in on us. Because that one duct fell so easily (held with what seems to be now brittle masking tape and some fine wire which is also brittle attached to the joist). I wonder if I shouldn't just retape and rewire the rest while I am at it. If I do, can I pull the pieces down and clean them or is that asking for trouble when it comes to putting them back together?
Part C is where ever there is cable for TV, the wire is coming up through the warm air vent opening. This means all the covers won't go back on flat at all. What are my options? I have thought of drilling holes right through the floors closer to the TVs (unfinished basement, hardwood floors) or can I drill through the metal floor venting and string the cable through it and the cover?
