How to Vent a Portable Air Conditioner through a Patio Door

Venting a portable AC correctly depends on how you place it. You wouldn’t want to use an extension line and try to straighten out your exhaust hose. Also, note that the hoses are not as elegant as the AC, so you need to consider the distance. Below are the steps on how to vent a portable AC through a patio door

Step 1: Decide the Distance between the Unit and the Door

Decide the Distance between the Unit and the Door

Before anything, you should measure the distance you need leave from the sliding door. Your space should contain the whole AC vent hose length. You need to get a portable air conditioner sliding door vent kit if your machine didn’t come with one.

When you have gotten the suitable vent kit, open your sliding door to get the space you need for installation. If the vent hose is around four inches, you need to open it up to 6 or 7 inches to get enough space. That gap automatically becomes your new door closing point.

Step 2: Mount the Panels and Vent Hose

Mount the Panels and Vent Hose

Install the vent in the gap you created earlier on the sliding door using the vertical panels provided in your kit. However, you can use wood to fill the gap if the panels don’t cover up and then paint them to match your walls. Ensure to use a weather sealant on the new panel to give it the best possible insulation.

The sealant prevents unwanted air or moisture from passing through the cracks. Additionally, use rubber straps on the panel edge to ensure tight-fitting when the door closes. Try and install the vent and panels to allow you to use the sliding entrance for exit and entry. But you should know that space where the vent passes won’t close.

Step 3: Attach an Adaptable Security Bar

After installing the vent and panel, you’ll notice that the sliding door won’t close to the lock. It means you need to attach an adjustable security bar or strong wood in the opening along its track. The bar helps you stop the push back from outside, meaning you should remove it before you open.

You can decide to remove hot air through a wall outlet into a storage room, garage, or outside. Ensure that there is no wiring or piping that goes through the wall, then cut it open with a jigsaw. Make the correct size of the hole you need and seal the edges with silicone caulk.

Dryer Vent Connection

Although it’s not advisable, some people may connect the portable air conditioner to a dryer vent. However, while dryer vents are about four-inch in diameter, most exhaust hoses have a larger size. But some pipes have a diameter of four inches and so would fit into the dryer vent.

Moreover, if the dryer vent’s outer opening has a flap, it will be difficult for an AC hose to shove it open. In this case, you need to replace the fold with a screen to enable easy passage of pipe.
