Which direction do return air vents face?
Supply air from furnaces and air conditioners should be on outside walls. The return air vent openings need to be on the opposite side of the room so the conditioned air is pulled across the room. If the supply ducts are in the floor, then the return air should be located up high.
Should vents point up or down?
Aim it upwards. In homes with central AC, vents are typically on the floor pointing upward for the reason you mentioned. You want to displace the hot air up top and hopefully get a current flowing. Blowing to the floor will not give much incentive for upper air to flow.
Do wall vents face up or down?
Registers that deliver warm air should be in the floor or low on the wall; registers to deliver cool air should be installed high up on the wall. Heat rises; cold drops, so aim highest as it will eventually go down (conversely for warm air). aqnd wrote: Aim it upwards.
How big should return air vents be?
A typical supply vent is 4 by 10 to 12 inches and a typical return vent is 16 by 20 inches or larger. Houses often have two or more return collecting points, each with a filter, which join before re-entering the heating unit.
Should you put filters in your return vents?
Do not put filters in your supply vents. Your AC system should have a proper fitting filter on the return side. By placing a good fitting, high quality filter on the return vent, you will remove particles from the air before they can enter the AC system.
Which return vents to close in the winter?
In the winter you want the cold air to be drawn through the return registers leaving the hot air behind. By opening the lower registers and closing the top ones you keep hot air in and draw the cold air out. Since cold air is heavy it will automatically flow down to the lower register.
Is the return air vent face up or down?
Should return air vents face up or down? Supply air from furnaces and air conditioners should be on outside walls. The return air vent openings need to be on the opposite side of the room so the conditioned air is pulled across the room. If the supply ducts are in the floor, then the return air should be located up high.
How many return vents should I have in my home?
Your Home Might Not Have Enough Return Vents Having several return vents (ideally one in every room, but even two or three is better than just one) creates consistent air pressure. If you have one return vent, your home is fine. Keep the doors to each room open so air can properly circulate.

Where are the return air ducts in a house?
Supply air from furnaces and air conditioners should be on outside walls. The return air vent openings need to be on the opposite side of the room so the conditioned air is pulled across the room. If the supply ducts are in the floor, then the return air should be located up high. This pulls the air across your body.

Is it better to have vents up or down?
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. In this manner, should vents point up or down?
How to improve the efficiency of return air vents?
The treated air is then forced out of the air vents into the rooms of the house, starting the cycle over again. Another good way to improve the efficiency of your return is to make sure the grills aren’t blocking the airflow.
