Short spoken advice (YouTube short) warning homeowners not to block floor supply vents or place couches directly against return vents. Explains airflow from floor vents rises, hits the ceiling, then falls along exterior walls to condition them; blocking vents can reduce room comfort and impair heating system performance (described as a “closing event”).
So it's going to affect that room, that situation. It's also going to affect the heating and air. So 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, hitting the ceiling and then falling back down to condition the wall. So if you have furniture or something in the way, obviously that can happen. So it's going to affect that room, that situation. It's also going to affect the heating in there itself because it's now starting to push. It's kind of like closing event. I think we talked about that before. I know there's an article on LinkedIn about it. It's kind of like closing event. I mean, it's pushing the air right back down to the hole, which cannot be good as well. So.
