Would it be better to place an air conditioning vent near the floor or ceiling?

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.
