486. Closing Your HVAC Vents
28 Jan 2026 · 1 min
Podcast episode (Derek Cole) advising listeners not to close HVAC supply vents. Speaker A answers questions from TikTok/LinkedIn, explaining that closing vents restricts airflow, strains the blower motor and duct system, disrupts designed CFM and return pathways, and may cause long-term problems despite perceived short-term savings. Uses a car-vent analogy to contrast short/home system differences.
Chapters
All right, got a lot of questions from the video on TikTok and I wanted to take a moment to answer a few of them. A lot of people took it personally. Some actually had good questions. First of all, there is a new article on my LinkedIn page. Don't close your H vac vents. Yes, I'm still sticking by it. Do not close your H vac vents.
Why?
You don't want to do this. Understand there's dampers in your floor grills or your ceiling registers. Just because you can close them doesn't mean you should close them. You don't want your straight airflow. You want to make air easy to get in, get out. You want to get into the room. You want to get back active, return. Closing your vents restricts airflow, strains your blow motor because it's trying to push air out. You're trying to bring it back in because you're closing the vent, it has nowhere to go. You're trying to bring it back in, which is a problem. But it's also a problem for your duct system. Your duct system can only handle the amount designed of CFM to handle. So if you're trying to push your back, it is then trying to push air forward and you're bringing air back. It's straining the blow motor, straining the duct system. Not a good long term solution. I think someone said in the comments it's just like your car. You know, you turn vent off in your car and the other one blows harder. Well that's true in the car and it could be true at home in some cases. But instead that car vent going 2ft away from it, your duct system has a what, 20, 25 foot run off the main trunk line to that room so that air has to travel back and try to go somewhere else. It's going to cause a strain. So I know you think you're saving money by closing vents and unused rooms, but the long term effects could be a problem. So don't close your HVC vents.
