Short podcast excerpt (single speaker) giving practical HVAC/home comfort advice: avoid placing furniture over floor vents or directly against return walls so airflow can condition outside walls; describes airflow pattern (air blowing up, heating ceiling, falling back down) and mentions a smoke test example. Recorded guidance is informal and prescriptive for homeowners.

What I have seen and what you need to be careful of is when the vents are in the floor, do not put the furniture over the vents. Do not put a couch smack dab against the wall at the return. That will cause a problem. So back up a little bit, give it a little bit of room. And don't put furniture and things like that over the floor. Grills. Because it's trying to. If it's on the floor. Okay. It's supposed to be on an outside wall. So it's trying to condition that wall. So the air is blowing up. I mean, if you were, like doing a smoke test and you can actually see it, the air would be going up, heating the ceiling, and then falling back down to condition the wall. So if you have furniture or something in the way, obviously.
