What is a HVAC return vent?

A return air vent is the part of your HVAC system that allows that warm air to flow back to your air conditioner. Not only will that air be cooled again, but it will also be cleaned by your air filter or air cleaner.

Considering this, what does a return vent do?

The supply vents in your home blow conditioned air out into your rooms. This air travels from your heating and cooling system, through your ductwork and out of the supply vents. The return vents in your home suck the air from your rooms into your return ducts and back to your heating and cooling system.

Secondly, is it OK to cover a return air vent? Avoid covering your cold air return vents with curtains, drapes or rugs. Always check your air filters and replace them when needed. Clogged air filters can also cause cold air return blockages.

Also asked, where do return air vents go?

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.

Should every room have a return vent?

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.
