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?]

In the notheast we tend to favor the heating load for designing the system, I am not to familiar with design principles in Georgia but would think you favor A/C. You have one thing going for you in that you have two systems, however we normally install a return air duct in any room that has a door [or can be closed off] this helps keep equal pressurization thru the system. You didn't mention the shape of the outlets or design. Ceiling diffusers are generally a pattern style which means they can direct air in 4 directions, 3 ways, corner, 2 way, or one way. It sounds like you have either a one way or three way. If you want to try an experiment just turn it in the other direction. This is generally easily accomplished with removal of a couple screws. Or you can head to the local home store to find a different deflection. Our rule of thumb is anything closer than 2 ft. to the wall should be directed to the room while anything out further can be directed in a multiple pattern, this applies only to ceiling grilles.sorry I got long winded, good luck (IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif)
