Installing an Air Conditioner Without Blocking Airflow

Properly installing air conditioner in a home will result in its correct operation without blocking airflow. The steps described below should help you properly install an air conditioner.

Tools and Materials Needed
  • Air Conditioner
  • Window
  • Screws
  • Screwdriver
  • Electric Outlet
  • Paper Strips and Tape
Step 1: Place Air Conditioner in Window

Lift the air conditioner unit into the window and set it in place. Close the window on top of the air conditioner in order to create a tight seal and attach the spacers that are typically on the side of the unit. If necessary, use a screwdriver to attach the spacers to the window frame in order to secure the air conditioner.

Step 2: Plug in the Air Conditioner

Take the cord to the air conditioner and plug it into the nearest outlet. The cord should have some slack so that it does not pull the unit too far forward or cause the unit to work improperly. Turn the air conditioner on to allow it to begin its operation and cool the room.

Step 3: Test Airflow Quality

Place several strips of paper with tape on the blower vents of the air conditioner. While the air conditioner is on, observe the unit to determine how the air is moving and whether the airflow is impeded in any way. This test can show you how the air conditioner is working and whether the filters need replacing or if the air conditioner was improperly installed.

After the unit has been in operation for a while, go to different spots in the room and determine if they are being cooled at a uniform rate. Again, if different areas within the room appear to be colder than others, this can indicate that the airflow is blocked or not being evenly distributed. Check the filters and replace any that are worn, reinstall the air conditioner unit and repeat this step.
