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?]

if I understand you correctly, you have hvac ducts in the ceiling of the first floor.

The idea is to wash the wall with warm air because the exterior wall is the coldest part of the interior space.

Up here in the northeast we have vents under most windows coming from the floor, air will pass in front of the window to warm the cold air that is coming from the window...i hope that makes sense.

Ok, now the real problem.

Do you have two zones??One upstairs and one down(two thermonstats)

if not you need them...if so, you should have some diffusers inside the duct work that regulates where the air goes...if not you should look into that. How you system is designed sounds different to me...

Usually the first floor is fed from the floor registers, then you send up trunk lines (big ducts) to the second floor and branch out from there.

If you have both the first floor and second floor feeding from the same trunk line that may be in your ceiling, you will need to put some diverters in the duct work...

Air will take the easiest route out of the duct.
Up is easier than down, and heat rises, so if all the ducts for both floors are being fed from the first floor ceiling, the majority of the air will travel up unless you force it to travel down...

I would recomend that you have an HVAC designer come out and take a look.
