Ways To Install Portable AC Without Window

Now, we present to you the ways that you can consider how to install portable air conditioner without window.


Way #1. Through your wall

This option allows you to be free of where you are going to place your vent passageway. However, you have to consider some factors.

One of these factors is your wall. You should select a wall that is composed of wood or drywall for easy drilling. Drilling through thick walls composed of bricks or stones is more complicated.

Make sure the wall you’re drilling through doesn’t have any cables or piping. Making a hole into these materials could disrupt your power and water supply.

To make ventilation possible with your wall, read the following steps.


Step #1. Drill a hole

Use a pen to mark where you’re going to drill. You can also follow the shape of your duct for the hole.

A hole saw is very convenient to produce a perfect spot for your vents. But they can only work for thin walls.


Step #2. Seal the flange

We will use the flange to connect the hose to your wall. So you’ll have two flanges for both sides of your border.

You can use caulk to seal it. Then, on the exterior side of your wall, close the flange with a vent grill cover.


Step #3. Attach your hose and cables

Snap the other end of the hose to the interior flange and the other one to the unit. Then, connect all remaining cables and wires.


Way #2. Through your sliding door

Consider this option as a larger version of your horizontal sliding window. For example, you can buy a tall panel that fits the height of your door.

Then, you can use this as your panel for your exhaust hose. Or you can attach the window panel that comes with your purchase. Finally, use a sealant or screw to seal the panels together.

Remember to drill a hole in the larger panel as well. You may also slide it through your door from one side to the other. Use your sliding door to hold it in place. After, you can now attach both ends of your exhaust hose to the panel and unit.


Way #3. Use your dryer vent

This choice is for you if you own a dryer that you don’t use too often. However, most specialists don’t advise this.

Your portable AC hose and a dryer vent look and function the same. So, why bother drilling onto a new hole when you can use what’s available?

When you buy a portable AC, there should be a ventilation kit. So you can remove the dryer vent from the hole and use yours. Or you might prefer using the dryer vent because of factors such as length. Or they are permanently attached to the hole.


Way #4. Through the ceiling

You can mostly notice a square hole in the ceiling with vent grill cover in some offices or establishments. This hole will be helpful to vent your portable AC unit if you don’t have any windows.

For example, you work in a private office with no windows, and you want to lower the temperature. You can attach the other end of your hose to the ceiling and let the warm air flow upward.

However, this option would make your vent visible and eye-catching. So, please place it in the corner of your workplace where it will be less apparent.


Way #5. Utilize your chimney

Homeowners do not frequently use this option because other options would work just fine and perfectly. Chimneys are meant to allow the interior air to escape. However, they are most commonly found over the fireplace or next to the kitchen.

So, it would be hard finding a way for your hose. But for this option, your chimney should be unused and clean.

We’re sure that you don’t want to put your exhaust hose on top of a flaming fire because it might melt. If you prefer this option, then you should call in a professional to position your hose because the procedure is complicated. And some chimneys are high.

We suggest using this if you have a smaller home such as a cottage or rethink other options.



And those are the possible ways on how to install portable air conditioner without window.

After finding a way for ventilation, you can directly attach the hose to the unit and hole plus other cables. And your AC is now ready to use.

In times like this, we must be resourceful and find a way to make the best of what we have.

We hope that these options could make your home a better place and improve air quality. Have a nice day!
