Deflectors for ceiling vents can be beneficial in improving airflow and directing conditioned air more effectively throughout a room. They help prevent drafts and ensure that the air is distributed evenly, enhancing comfort. While not always necessary, their use can optimize heating and cooling efficiency, especially in spaces with high ceilings or unusual layouts. Ultimately, whether to install deflectors depends on the specific needs of the space and the existing HVAC system.
Does not matter. Air will displace naturally when pushed into a room from the vent. Vents and ducting are laid out according to the plans of the unit. That is the only reason for top vents and bottom vents. If you are speaking of the intakes, the same principal applies.
In my house there is. I call it "my arm". If you have really high ceilings, I suppose you could use a pole of some kind.

It is generally better to place an air conditioning vent near the ceiling. Since cool air is denser, it tends to sink, allowing it to distribute more evenly throughout the room when released from a higher position. Placing vents near the ceiling can help promote better airflow and maintain a more consistent temperature, enhancing overall comfort. However, the specific design may vary based on room layout and heating needs.
Yes they do, but they are hard to find. I've found ones for 24 x 24 diffusers, but can't find one for a 48 x 4 inch diffuser!
Cool air falls toward the floor. Deflectors shouldn't be necessary unless the vent is behind a curtain or something, or if you want to deflect the cool air toward your easy chair.
There may be something blocking the deflectors from sending air up there.
Thanks for answering the question Should ceiling vents be directed towards the window or the room? NOT
on the floor on the floor
should be on floor.
When you say "exhaust vents in your ceiling" I assume you are referriong to the heating and AC vents inside your house and not the roof vent on the outside used to vent the attic. It is most likely that the duct work was ran in the ceiling for ease of installtion or the house may be built on a slab and they did not want to run the duct work through the slab.
Vent air deflectors are used to redirect airflow from heating or cooling vents to improve comfort and efficiency in a room. To use them, simply install the deflector over the vent, ensuring it is securely attached and positioned to direct air where needed—either upward, downward, or sideways. Adjust the angle as necessary to achieve the desired airflow pattern, and periodically check to ensure it's clean and unobstructed for optimal performance.
The purpose of Ceiling Vents is to provide Ventilation in a room where it may be necessary, such as a Science Lab. Because gases generally rise (as they are hotter than the air and so less dense), they can escape out of the ceiling vents without causing any harm to people inside the science lab. They can also be used to help deal with a fire.
Heating vents should be located near the floor since hot air rises. If the heating vents are located near the ceiling the heat would stay there and not warm the room.
Cose the high vents in the winter and low in the summer..
Ceiling. Cold air fails
