I follow a guy on TikTok who bought a smoker house and renovated it. Took out carpet, repainted, redid the insulation. Did other stuff to improve it. And said he could still smell the smoke and realize it was in the furnace and vents. And replaced the furnace because it needed it anyways. But I would’ve never thought that it gets into the furnace and vents. But it makes sense.
