furnace vent hidden under sticky floor tile

Ok I have no furnace vent in the bathroom but in one corner the tile is warm when the furnace runs. It appears they might have put new tile over the old tile and thus covered up the furnace vent. How do I remove the sticky tile to see if there is a vent hidden underneath and then re attach the tile if there is none. By sticky tile I mean the kind that you peel and stick.

You should be able to just step on it and see if it flexes. A sharp box cutter could be pushed down on top..it should slide in between the louvers if there's a vent. Or drive a very small nail..should be able to tell if you hit metal or subfloor.

Hmm as I remember..this is a mobile home? Why not go under and look?

Heat the tile with a hair dryer, that will cause the adhesive to release.

Well i made a hole with a long screw and there was air coming out from the hole with the furnace running. You got the tile then I guess a wooden floor then the vent. So do I take a jigsaw and just cut till I hit metal?

Ouch...a long screw? Heck there could have been a duct there where it wasn't insulated.

I'd do the blow dryer thing and remove the tiles. Or cut a small area to see what you find. It's peel and stick..should be easy to cut through.

Just be careful. You could end up with a mess.

Most MH have a particle board sub floor. Generally the duct work is run just under the floor and will run in a straight line in one of the joist cavities. It's possible they laid a layer of plywood over the subfloor prior to laying the tile.

well there is a vent hidden under the tile and subfloor. Right now i got a 1/2 inch by 2 inch hole cut out in the tile and floor. The entire opening which is still hidden is 4x8. I measured the other vent openings in the floor and marked out the edges of the floor vent in the bathroom which is the same size. So i just have to get a vent cover for a mobile home

its done. I cut the hole out using a jigsaw on slow speed. The floor that was layed down is very thin maybe the thickness of 2 bingo chips. I installed the vent and now the bathroom has heat.
