Does not matter. Air will displace naturally when pushed into a room from the vent. Vents and ducting are laid out according to the plans of the unit. That is the only reason for top vents and bottom vents.
If you are speaking of the intakes, the same principal applies.
Because heat rises.
In my house there is. I call it "my arm". If you have really high ceilings, I suppose you could use a pole of some kind.

Floors in heating season, ceilings in Air Conditioning season
Hi: would love to help, but your question leaves more questions than answers. I simply do not have enough to go on here to help as much as I would like to. You are only as good as your information & I'm afrain you tell me very little. Assumptious guidance is bad business. Tell me more about your system/systems, and how they are arrainged in your house to work for you and all you can about the house to. Thanks: Jimiwane or you could open your second floor vents all the way, and crack the vents on your second floor. Works like using Balance dampers, but not as effective as having your system balanced properly.
on the floor on the floor
should be on floor.
Heating vents are typically placed near the floor to ensure better air circulation and distribution of warm air throughout the room. Placing them near the ceiling may lead to stratification of air, where the warm air stays near the ceiling and doesn't effectively heat the room.
Heating vents should be located near the floor since hot air rises. If the heating vents are located near the ceiling the heat would stay there and not warm the room.
Ceiling. Cold air fails
up in the summer and down in the winter
Cose the high vents in the winter and low in the summer..
Because heat rises. Ergo, if they were located by the ceiling, it wouldn't warm the whole room efficiently.
Might be a blockage in the ductwork somewhere.
It would be better to place the heating vent near the floor because the heat will travel up and down, so that way the room would be heated evenly. If you place it near the ceiling, the heat would not heat the floor that well, since the heating vent sucks back in the heat
Either way will work ok as long as the system is designed that way from the beginning. The best place for the air conditioning registers (vents) will depend on who designs the system and the construction of your home. In some homes it is not practical to install the registers in the floor that have a concrete foundation. If you have a very low or flat roof it may not be practical to install them in the ceiling. Houses that are cooling most of the year have the registers in the ceiling and home that heat most of the year tend to have the registers in the floor.
Heating vents should be placed on or near the floor because heat rises. In rising, it will warm the air of the room. If the heating vent were near the ceiling, the room would stay chilly, even though heat was being poured into it.
