How to Redirect Airflow From Window Ac

How do you redirect airflow from a window air conditioner? In this post, we will explore how to redirect airflow from window ac unit to be directed outside rather than inside. This makes it possible for you to put your AC in a bedroom without worrying about being too cold from the air blowing on you all night long.

How to Redirect Airflow From Window Ac

One way to do this is with a hose and some strategically placed buckets or bowls. Another way is by using a vent cover insert that has been specially designed for this purpose. These inserts are inexpensive and easy to install, making them an excellent choice when deciding how best to deal with the problem of having an open window near one’s bedside while running cooling equipment during warm weather months.

Materials You Needed

  • Utility knife
  • Screwdriver

Step by Step Guide on How to Redirect Airflow From Window Ac

Step One: Gather Supplies

For this project, the supplies are minimal. All you will need is a Sawzall or equivalent reciprocating saw, duct tape, and Teflon Tape. Please note that your window ac unit must be plugged into an outlet at all times during this process.

Step Two:  Remove Window Ac Unit From Window

Using the saw, remove the window ac unit from the window. You will need to unscrew or cut any brackets that hold the unit into place. If there is a filter, you may want to vacuum it off of any debris before attempting to pull out this step.

Step Three: Remove Plastic Housing On Window Ac Unit

Once you have removed the window ac unit from the window, remove the plastic housing around it. This will expose the blower motor and fan inside of your unit and allow airflow to pass through.

Step Four: Cover Blower Fan With Duct Tape

To create a seal for this project, we can use duct tape to cover the blower fan. This will prevent any cool or warm air from leaving your room and allow us to redirect it back into the room we are currently in.

Step Five: Tape Off Vent Opening

To make a seal for this project, we can use duct tape to cover the blower fan. This will stop any cool or warm air from escaping your room and allow us to redirect it back into the room we are currently in.

Step Six: Reverse Direction Of Fan

Now that airflow is being redirected into the room you are currently in instead of outside; we need to reverse the fan’s direction to push air into the room instead of out.

Step Seven: Plug Window Ac Unit Back In

Once airflow has been redirected, plug your window ac unit back into an outlet and power it on. You can now enjoy fresh air within the room you are currently occupying!If you want to enjoy fresh air in the room you are in, you need to redirect the airflow and then plug your window AC unit back into an outlet.

If there is no longer a vent opening for airflow to come through on your window ac unit, you can remove the duct tape from the vent opening and place a small hole or crack in it to allow a steady stream of air.

Step Eight: Enjoy Your Fresh Air!

Once you have finished powering your window ac unit with redirected airflow, enjoy your fresh air comfortably while staying cool. While this project will allow you to experience fresh air in your room, it does not allow any ultraviolet light to enter the space.After you have set up your window air conditioner unit to redirect airflow, you can enjoy fresh air in your room while staying cool.

However, because this project does not allow any ultraviolet light to enter the space, you will need to duct tape the vent opening and place a small hole or crack in it to allow a steady stream of air.

Once You Have Finished Powering Your Window Ac Unit With Redirected Airflow, Enjoy Your Fresh Air Comfortably

If you require both UV light and airflow from within the room, I recommend using a high-quality ozone generator that works in conjunction with your window ac unit rather than making this project yourself.


Can I Tilt a Window Air Conditioner Into My Home?

You can’t tilt an air conditioner out your window because the refrigeration lines are full of chemicals that will kill you if they leak. If the unit falls over on its side, the lines will burst immediately and also dump their deadly load into your home.    

Can I Get a Window Air Conditioner to Fit Into a Small Space?

Room-sized window air conditioners will not fit in the space you have left. You can get a much smaller one, but it won’t function as well, and you’ll still be cold because there’s no way to remove enough heat from your home with an underpowered unit.

How Can I Make My Window AC Unit More Efficient?

A window air conditioner will not increase your home’s efficiency. They are designed to cool one room, often a small one, and selling them with the idea that you’ll be “cool for pennies” is misleading. Instead, purchase an efficient unit or install central air conditioning if possible.

Can I Put My Window AC Unit Outside?

Window air conditioners are designed to stay inside, where the electrical power is. They should not be put outside in any way because they don’t have the weatherproofing you need to keep them safe from rain and snow. So don’t even consider it.

Should Window Ac Vents Point Up or Down?

There is no real right or wrong answer to whether ac vents should point up or down.  This happens to be a personal preference that some people swear by, and other people feel very strongly against.  

The choice will probably come down to what you think looks best and what works well with your home’s layout.  Most people believe that it doesn’t matter one way or another, but this article is for those who care about how their ac vents look and where the air goes.


In the end, it’s important to understand where you want your airflow from your window AC unit. For example, if you have a room that gets too hot with the air on and don’t need any cooling, but do want some warmth in other rooms or hallways, then an exhaust duct is perfect for this purpose.

On the other hand, if there are no adjacent rooms that can use warmer air coming from your AC system, which would lead to wasted energy costs without much benefit, then a supply duct will work better.
