Register placement

Afternoon all,

I would like some feedback on the best place to install registers throughout the house and/or in specific rooms. I have attic access over every room in the attached layout, and I would like some feedback on the best places to put the supply and returns.

I have seen many split levels install one large return near the stairs and feed each of the rooms. Is this a common practice for a split level home?

thanks for any input.

Welcome to the forums.

We don't know your location - is this mostly heat or AC or both?

I prefer many local returns as to one giant.

New Jersey 07849.

Only for AC. I currently have hot water baseboard heat.

I was thinking about the larger return by the stairs and smaller returns in each bedroom.

With forced hot air furnaces, A/C units share the same duct work. All registers will be on an outside wall under or near a window. I do not know why that is.

HVAC guys like to set registers under windows both because they are less likely to get covered up with furniture and it places the heat where the most likely area of heat loss is.

Marksr, interesting. That begs the question. It seems that that would be the wrong way to do it. Assuming a perfect world, would not a heat register located at an inside wall or perhaps in the middle of room (not practicel of course) be better? The furnace would cause a positive pressure in the room and force or prevent possible cold air from entering from outside. Same scenario for the AC.

The heat and moving air helps prevent condensation on the windows in the winter.

If this is only for AC, I would put the vents and returns high on the wall.

I agree. Cool air falls to the floor while hot air rises.
