How do I Set Vents to Maximize Air Conditioner?

Air conditioning vents are the access points from which air enters the room from the air conditioning ducts and system. The vents of the air conditioning system are adjustable to maximize or minimize the flow of cooled air. By simply adjusting the vents, the air conditioner will produce more or less air in occupied rooms. Closing the vents in unoccupied rooms will produce greater airflow in other rooms.There are also a few maintenance procedures that can improve the airflow through the vents and maximize air conditioning.

Adjust vents to get the most out of your air conditioning.

Closing and Opening Vents

Step 1

Locate the vent in an unoccupied room. Close the vent to direct the airflow into another room to maximize the air conditioning in the occupied room. If operated by a lever, move the lever on the side of the vent. If operated by a knob, turn the knob on the side of the vent.

Step 2

Push the lever down, or turn the knob counterclockwise to close the vent.

Step 3

Open vents in an occupied room. If operated by a lever, grasp the lever on the side of the vent. If operated by a knob, grasp the knob on the side of the vent.

Step 4

Push the lever, or turn the knob clockwise all the way to open the vent. Keep the vents in occupied rooms open all the way to maximize airflow.

Step 5

Point the open vent toward the center of the room. The vent needs to direct airflow to the center of the room and not directly toward a wall, the floor or the ceiling. Ensure there are no objects such as furniture or curtains blocking the airflow coming out of the vent.

Step 6

Clean the vent if blocked by dirt or debris. Dusting the vent cover on a regular basis can prevent slat blockage that prohibits airflow. If necessary, remove the vent cover and clean with soap and water.
