OT - Any HVAC Types around?, Vents, point which way? Options

[DuckRyder]

O.K. heres the question:

In my house all of the vent louvres point toward an outside wall (and they are all near a wall) as a result, it usually feels real warm by the wall and real not warm in the room.

Is there a proper way to determine which way a vent points, and what is it.

(I'm talking about the downstairs, and the vents are in the roof, I don't ever go upstairs and there isn't any bitching from up there, so it must not need fidling with)

Thanks in advance for any enlightenment. [wheres the blanket smilie?]

For heating you heat the coldest thing in the room usually a window since they are the biggest heat loss vs a wall. The idea is also to take advantage of convection to help circulate the air so you don't have a thermocline situation. (layers of cold to warm air)
Sizing of the cold air returns and location are important as this helps with the flow of air.
Could be just a balancing situation also that a heating tech could resolve.
