Cold Air Return Vents

These are the vents that are usually on the wall and they do not have a control mechanism to open or shut their flow.
Cold air return vents. Their purpose is to allow air to return to the furnace to be heated or cooled. Remember that when choosing sizes, always measure the duct opening. Try the following, since it is still the winter heating season:
It is an air inlet. Some systems have two sets of return vents, one up high for warm air and one low to the floor for cool air. If you block the return air vent it can prevent your heat pump system from working properly.
No, the return air vent is a very important component to your heat pump system and cannot be obstructed. Shortly after we developed a method of making cold air returns. Our cold air return vents actually have a lever that allows us to open or close the vent depending on the time of the year.
To explain the components of a forced air system: During cold weather, gas burners create heat in the heat exchanger (image 2), which in turn heats the air. They can be placed into staircase cavities, stacked closets that run one on top of the other, or in stud cavities in the wall.
It draws cool air from all the rooms in your house that have a return vent and pumps hot air into these rooms through the heating vents. The return air vent openings need to be on the opposite side of the room so the conditioned air is pulled across the room. It accomplishes just what the various names imply, return colder air, via registers and ductwork, to the.
If you cover the return vent in a particular room, that room won't get as warm as the others. If your home has returns in most rooms this is. This pulls the air across your body.
