Also to know is, which way do air vents face?
They should blow the air towards the wall. You don't want the air to be felt blowing on you directly if you're in the room. By blowing the air that direction you are 'washing the air' against the wall creating a current for the the return register to pull that air back into the system.
Likewise, which way do wall vent covers face? A downward direction is preferred more, as air always rises up after collecting heat from below. The velocity of air will have to be low and linear by the time it reaches occupants.
Considering this, which direction should ceiling return air vents face?
If you have an Air Return is on the upper wall I like to slant the louvers upwards so that floor traffic does not view into the duct opening. That is the same with Supply vents as well IF you have adequate air flow and few cold or hot spots in the room from inadequate air flow or distribution.
Should I use vent deflectors?
If your goal is to direct the airflow more precisely, vent deflectors are a better choice. Directing airflow away from curtains, plants, and equipment to prevent disruptive breezes. Directing airflow away from walls and furniture, and toward the center of the room to provide more even temperatures.
