Steps To Install Portable AC in Horizontal Sliding Window

Portable air conditioners have been popular these days because of how convenient and affordable they are. If you want an AC that could release air cool enough to give freshness to your room, then this type of air conditioner is for you.

But is the installation challenging if you have a horizontal sliding window? On the contrary, it may be confusing and complicated. It’s tough to do a particular task if you don’t know where to start, do you agree? But these steps are easy to follow. You can even do this in less than 15 minutes! At the end of this article, you can certainly do this on your own. So, here they are:


Step #1. Collect all necessary materials

Ensure you have all the things you need before starting, namely your window kit and AC unit. You might also need something to secure the hose and ducts, like duct tape or screws. Don’t forget your scissors.

Depending on your window set-up, you might need some fasteners and a drill or plain screwdriver. Go over the items in your window kit. For example, check if you have a window kit plate, exhaust hose, screws, grated cover, and a duct connector. Some brands and models may differ in additional accessories, but these should be present.


Step #2. Determine the location

In identifying the location, you need to consider some of these factors:


Factor #1. Space

The allotted space for your AC should be enough for its width. And since it has an exhaust hose attached to it, there should be extra space so that it won’t bend. Too little space for your AC or keeping it in a narrow area would prevent the air from circulating onto the whole room.


Factor #2. Distance between the outlet and window

Later on, you’ll connect the hose or cable to the central AC unit. So, it would be best if you place it near the outlet and window. We suggest that the distance between the two is balanced or equal. This statement means that the position of your AC is enough to reach the outlet and window opening at almost equal distances.

Factor #3. Window height

The average size of your portable AC ranges from 3-4 ft or more. But it would help if you also considered the height of your horizontal sliding window. It shouldn’t be high for the exhaust hose. The hose might not reach the window, but the hose will keep getting loose if you force it. Or you might end up damaging the AC unit.


Step #3. Secure the grated cover

Most window kits include about three window plates, and one has a hole designed for the exhaust hose. First, you have to secure the grated cover onto the hole. However, some portable ACs include the grated covers onto the end of the exhaust hose. Secure the cover in place using a screw.


Step #4. Install the window plates

Open your horizontal sliding window and slide through your plates. You have the choice to install just one of them. Or you can use all three. It depends on your window set-up. Assure that the grooved or hollow side of the hole faces the outside world, which means that it doesn’t look toward you.

And close the window until it is in contact with the board to hold it in place once you’ve set your plate(s). You can also screw it in place if needed. If there are gaps, you can use duct tape for a better fitting.


Step #5. Connect the hose and connectors

Attach the duct connector the one end of the exhaust hose. Seal the connector well using a screw. You will connect this end to the back of your AC unit. Turn it clockwise or snap it on until fastened tightly. Place the other end onto the window panel hole. So, make sure that this side will include an oval-shaped nozzle that fits the gap perfectly.

Ensure that all of those components are precisely sealed, especially the nozzle, to prevent leakage. We also mentioned earlier that the exhaust house should not bend since the air won’t circulate. And it could cause tearing in the surfaces of the hose.


Step #6. Test your AC unit

This step will serve as your finishing touches so that you can make some adjustments. Plug your portable air conditioner into the outlet and check if it’s working well. Make sure there aren’t any leaks that might cause an electrical problem. If there are leaks, use your duct tape to fix them.

Or you can adjust the connection of the duct or hose because it might be loose. We suggest that you go through the manual in case you miss something. And that is how to install portable air conditioner in horizontal sliding window.
