First of all, this run is for data lines, not AC but this seems like the best forum…
My house is a 2 story with slab floor. I need to get some wires from the attic to the lower floor. On the lower floor, one side of the wall is a garage so I could open that wall if necessary (it is finished but not painted). The same wall on the upstairs is a bedroom/hallway which is finished and just painted etc. so I don’t want to cut open drywall or even try using a right angle drill through an existing hole.
First off all, the upstairs room already has a wall plate with cable in the wall/stud bay I plan on using and I might as well use that same stud bay space. It’s possible that there is already a hole running through the floor for the cable. If not my plan would be to drill from below through the floor plates from the garage.
So before I go off half cocked I thought I’d run my plan by someone in the know..
1. Open a small hole in garage next to ceiling right below stud bay with cable in bedroom. Try to determine if there is already a hole with cable.
2. if there is no hole, use a right angle drill to drill a hole upwards into stud bay. Having an existing cable access box hole will allow easier fishing of wires past access.
Does this sound like a reasonable plan?
It appears that all of my AC wiring goes from the attic straight down through to the second floor (becuase it’s slab floor) but your not really supposed to run data cables (i.e. CAT5e) next to AC and the holes probably wouldn’t be big enough anyway.
Is it possible to get a mechanics mirror into the hole and look down at the plate? Depending o your area it may be stuffed with fire caulk or foam to seal it off so the hole doesn’t act like a chimney.
I would try to avoid cutting through the drywall in the garage to preserve the fire rated integrity.
You may also have thermal insulation in the wall that can make fishing difficult.
