Step Two: Measure the Window

But if your window unit is huge, then maybe two sets of drapes would do the trick as well as blocking out light, to begin with.

Blinds or drapes might be better suited for you if you have natural sunlight coming in and you don’t want to shade the window. But, if you want to save money on some drapes or blinds, try shading.

Step Six: Other Methods

There are other methods that some people have used to block out light from their window ac unit without having drapes or blackout curtains. One example of this is tinting your window. If you have a car, you might know that having the windows tinted darker makes it harder for outside lights to get in and allows less heat inside while driving during the summertime.

You could do something similar with your window air conditioner unit. Another example is using tin foil on the inside of the window. This might not be aesthetically pleasing, but it will do the trick of blocking out light if you are looking to save money on some drapes or blinds like mentioned above.

Blocking out the light from your window ac unit is essential if you want to be able to watch a movie or play video games without a glare getting in the way. Using drapes or blackout curtains is a great way to block out light, but blinds are also an option and other methods mentioned above if you are trying to save money.

How Do You Block a Light but Not Airflow?

Use caulk to block the light from coming in. It is best if it is white or a color that looks like a window’s frame. Clear caulks let too much of the actual color of the window show through, and colored caulks have more of a tinted look than an opaque one.

The best caulk to use is an opaque, weather-resistant one. Use the smallest bead possible, so it goes farther and does not look messy. It may take a couple of applications to get it just right. This will help in how to block light from window ac unit.
