476. Why the Need For Air Returns
28 Jan 2026 · 2 min
A listener asks if every vent needs an air return. The answer: more returns improve airflow, especially in rooms with closed doors. Place them near distant bedrooms or on opposite sides of the house, and avoid pulling air from attics or crawlspaces.

Do you have to have an air return for every vent or could you have the vents in the bedrooms and half in the hallway?

Be sure to tag me or DM me on Instagram Derek Mcole so I can say hi. Thanks again for listening. And let's begin.
When we zone houses. Well, let's start here. Let's back up a little bit. The more returns and the bigger the return. It can't be too big, you can't have too many because you want the air to get back to the unit as easily as possible. So for example, if you got a 1600 square foot house, the back bedroom at the corner in the returns towards the other side of the house, it's.
Going to be harder for that air.
To come back to the return. So I mean, it's not a bad idea in that situation to have one on this side of the house and have one on this side of the house. That way the air can come back as quickly as possible and can get back to the unit. So the more returns the better. I mean, obviously you don't want to go crazy and put, you know, 20 returns in a 900 square foot house. That's probably not going to work out. But I think I know where you're going with this question. When we zone, when we zone houses and doors stay shut in those rooms, we like to put a return in those rooms because that all feeds back to the main return that can get to the unit. So for example, when I was a.
Kid living at home, our house was.
Zoned, so I kept stayed in my room quite a bit and shut the door. So every room had a return. So it made it as easy as possible. You don't necessarily have to do that, but if that door is going to be shut, and I think we covered one time before about, you know, carpet and air gaps and things like that. If it's going to be hard for the air to get back to the return, you want it in that room. So that would be fine as well. The bigger return, the better. I mean, anything that eases up the fact that air needs to get back to the unit is better for it. So in that situation with the 1600 square foot house, I mean ideally you want to have one over here and one over here. You just don't want one return because it makes it hard for that bag room for the air to come back to it. Now it's going to get air one way or another. You want to get clean, filtered air. You don't want to get air from the attic or from the crawl space that's dirty and dusty and smelly. You want to control as much of that as you can.
