No Window? No Problem. Here’s How to Vent an Air Conditioner Without a Window
Have you ever wanted to install an air conditioner in a room that has no windows? If so, you’ll be happy to know that it’s totally possible to do. Although window air conditioners are the easiest and most popular option, there is a way to vent an air conditioner without the need for a window. No matter what size room you are trying to cool, or what type of air conditioner you want to install, here is all the information you will need to understand the basics of AC ventilation so you can keep your windowless rooms nice and cool.
Basics of Venting an Air Conditioner Without a Window
If you don’t have a window available to install a window air conditioner, there’s no need to worry. Venting an air conditioner through your wall or ceiling is relatively easy and can provide effective cooling in any room of the house. The basics of venting an air conditioner without a window involve attaching an exterior vent to the outside of a wall or ceiling, as well as an interior vent that connects to the air conditioner.
Preparing the Room
The first step of installing an air conditioner without a window is preparing the room you want to cool. Make sure the room is free of clutter and large furniture pieces, then measure the length and width of the walls you plan on cutting for installation. Also, take note of any electrical wiring and other important components like water lines that may be hidden within the walls in that area of the room.
Attaching the Exterior Vent
Once you’ve identified a location for your exterior vent, use a stud finder or knock test to identify where it needs to be cut out for installation. A good-sized hole for a single-hose air conditioner should be around 8 inches wide by 25 inches tall. After marking out your measurements, use a saw or jigsaw to cut out your opening and clean up any rough pieces around the edges with sandpaper or an electric sander.
From there, attach the proper mounting brackets behind your new opening, then slip in your newly purchased exterior vent cover facing outward and secure it with screws. At this point in time, you should also check to make sure you have a good seal between your new opening and the vent cover by inspecting closely for gaps or cracks that may occur after installation. If needed, caulk these cracks with waterproof sealant depending on your preferences.
Installing the Interior Vent
Once your exterior vent is properly installed and sealed off from the outside elements, it’s time to install the interior components needed for your air conditioner. Start by cutting out an interior hole that’s slightly smaller than the outside opening you just created. This will help keep drafts at bay while also creating ventilation between both parts of the system. Then attach a plastic mounting collar over this new opening, then secure it with nails or screws. This piece will act as the outlet between both openings so make sure it fits snugly inside before moving on.
Next, slide in your newly purchased interior vent cover so it fits inside your installed interior space, and secure it with screws. Pay close attention that this fits snugly as well so no drafts are present during operation. Finally, attach an accordion-style aluminum tube from one opening inside to another outside. This will act as an insulation barrier between both parts of your system while also allowing airflow from one spot to another. The piece should fit snuggly in place but you can always use additional sealant for extra protection against any drafts or leaks if needed.
By now, you’re close to having your new air conditioning system up and running! If you haven’t already done so, attach your air conditioner directly to the back side of your interior vent by aligning it with pre-drilled holes on either side. Make sure all the screws are tightened securely before continuing forward with installation. Then plug in all necessary power cords and turn on your new air conditioner. Now you can enjoy optimal cooling in any room without ever having to install one through a window!
Venting an air conditioner without a window may seem intimidating at first, but with the right information and tools, it’s not as difficult as it may seem. All it takes is a bit of patience and attention to detail, and you’ll be able to enjoy optimal cooling in any room of your home.
