How Do You Install A Window Air Conditioner In A Jalousie Window – 10 Steps

These 10 easy-to-follow steps below should be enough to install your Window AC unit to your jalousie window.

  • Measuring the Jalousie Window: 

The first thing that you need to know is to find out what type of ac you need. For that, measure your jalousie window with a measuring tape. Make sure you keep track of the numbers properly and keep a note if needed. Do not measure the distance from corners to corners. Just take the measurement from the horizontal sides of the window and the vertical sides. Be sure to measure the window along with its panel. 

  • Purchasing the Air conditioner :

Now comes the part of buying the right shaped air conditioner for your window. For that, you need to do some simple calculations like finding out the BTUs needed for your room. You need to make sure to count the areas of your room where airflow is interrupted as air will go out through those places, and it will be hard for the air conditioner to cool down the air in your room. If the measuring indicates the maneuverability of a window AC unit is possible, then install a window AC unit. Otherwise, you can even check out the Portable Air Conditioner Units. They are also worth it if it’s a small room. But, It is best to opt-out of a window ac unit instead.

  • Purchasing a window vent kit : 

Now, you need a way to fix the AC unit to your window. For that, try purchasing a window vent kit. The vent kit will be attached to your AC unit to accommodate the airflow in and out of your room. You most probably won’t find the perfect fitted vent kit for your window. So, try purchasing one that can be changed to different sizes. 

  • Measure one of the window sash :

Measuring the length of your window sash is important to find out your equipment as well as your window AC unit. The measurement will determine whether it is possible for you to fit the AC unit there or not. Moreover, it will also conclude which size kit you can use in your window. Therefore, be sure to measure the sash and take notes of the measurement to purchase the perfect equipment. 

  • Removing the flaps : 

After you have bought your equipment and AC unit, now it’s time to fit it in the window. For that, take a screwdriver or the hardware you need to unscrew the top flap of your jalousie window. Now loosen up the screws in your vent kit and Attach your AC unit. The screw should be at either end of that section.

  • Screwing the flaps on the AC unit :

Once you have detached the window section, you need to add the AC unit there. Put screws through each hole located on the edge of the AC unit wall and into the top of the jalousie window. Be sure to install it with proper care and fix the screws tightly. Now, attach the other flap. Secure it properly by tightening the screws. 

Everything should seem perfectly fitted, and now you can install the AC unit to your jalousie window. If your window is high above the ground, keep a look at the outside for people. If anything goes wrong, the AC unit might fall and cause an accident. So, make sure there is no one outside your window.

  • Sliding the window vent kit into place:

Now it’s time to fit the window vent kit. Using the bottom flap as a guide, secure the vent kit in and flush it against the AC unit. This will keep it secure when your room is being cooled.

  • Checking the AC through power outlet:

Now plug your AC unit into the power outlet and see if everything is okay. Turn the AC on and see if there is enough airflow coming from the vents.

  • Cut out hole for the power cable :

If your AC unit has a power cable on the back of your window, then you need to make a hole to bring them into the house. You can directly use it without making a path through the wall. 

However, there might be air leaks, and you don’t want to waste your power. So, take a jigsaw or any other cutting machine to dig a hole inside the wall (if needed) or make a hole inside the sides of your window. 

Be careful not to damage any electrical wiring or gas lines. The jalousie window should already have plastic film covering it from when you first took off the flap on top of the window.

  • Covering the AC unit :

When the hole is made, now it is time to cover the AC. You can cover it with plastic film and also tape the hole around so that there are no air leaks or gaps between your AC unit and the jalousie window. This will keep the cool air inside your room.

Put Flap Back In Place And Finish Installation

Once cut open, a hole is finished, put the back flap in place and tighten screws to ensure it is secure. Reattach any other louvers that have been removed from the jalousie window as well.

Cleanup And Ongoing Maintenance

When you have installed the AC unit, make sure you clean the AC unit properly. You can use a vacuum to clean it. Keeping the window air conditioner clean can help the airflow stay consistent as there will be dust that will always pose a problem.

Try using the manual that came with your window air conditioner to know more about the cleaning process.

How do you install a Window AC unit in a Metal Frame?
