Installing a small window-mounted air conditioner is a simple task for anyone who is at least marginally tech-savvy. Below you will find the basic comprehension guide to doing this by yourself and saving even more money from your bill.

Step 1

First and foremost, make sure you have an outlet close enough to your window because most window AC units are equipped with shorter cables, so check out on which side your outlet lies before continuing. Always make sure to consult your product manual, which comes in the package, and follow their instructions besides the guidelines provided in this article. 

Step 2

Using a measuring tape find the center of your window in order to position the unit properly. Check if there are weatherstrips available in the unit packaging and, if they are provided, attach them to your window. If not, your air conditioner unit will work just as well without them.

Step 3

Next thing, you should attach the panels on both sides of the unit and secure them with the screws provided by the manufacturer. Make sure to use all the screws in order to prevent any warm air from getting inside the room or polluting the space.

Step 4

Now comes the last of the tricky parts and you are almost done. Center the AC unit and secure it on your window. If done correctly, the window would be able to slide on and perfectly fit on top of the unit without any applied force.

Step 5

Now that the hardest parts are behind you, all you need are a few L brackets to hold the air conditioner in place and firmly connected to your window. Most products come with brackets added to the installation kits but if this is not the case, you can get some from your toolbox or purchase them at your nearest hardware store.

This is essential to ensure that AC is secured in place and you will not hear a slam in the middle of the day through your window.

Step 6

Lastly, if provided with the product kit, make sure to add the padding for the sides of the window to secure the unit in place and close up any gaps. If there are no paddings provided, then simply extend the air conditioner’s side panels and attach them to your window with screws the company provide in the box, or simply some from your toolbox.

You should have no problem installing your compact air conditioner by yourself using these guidelines, however, bear in mind these are just that – guidelines. If you do not feel confident in your skills or the provided instructions look too complicated, do not hesitate to call a professional to install the unit for you, pain and frustration-free.
