Why are heater vents placed under windows?
The movement of cool air creates floor drafts that most people find uncomfortable. The placement of forced-air heat registers or baseboard heating units under the windows counteracts this process by sending up warm air to mix with the cool. The end result is that the room feels more comfortable.
Where should heat vents be located?
Supply register vents should be in every room as well. Located on the outer walls, under windows, in the ceiling, or on the floor, placement depends on the heating or cooling system as well as the construction of the home. Supply vents help change the room temperature to your desired heat or cool setting.

Why is there no air flow in the upstairs vents?
I have recently seen several newer furnaces installed that appear to be set on a very low speed when the heat or air conditioning is on, when it should be at maximum. In that scenario, there may be a high enough volume of air to provide reasonable flow at the lower levels of the home, but not the upper floor.
Can a car vent blow cold one side and hot the other?
