A Complete Guide on How to Install a Window AC Unit in Your Room

With summers around the corner, you must surely be looking for ways to beat the scorching heat. According to Meteorologists, the 2021 summer in the US will be hotter than usual, making an air conditioner a must-have when preparing for the season.
If you are looking for a classic, affordable option to cool down your room, then a window air conditioner is an excellent choice. It is a reliable option that can cool a room of various sizes. Newer models make less AC noise and are more energy-efficient than those built a decade ago. You can also easily install a window aircon without calling a professional, and this guide answers all your questions on how to install a window AC unit.
Things to Consider Before Installing a Window AC Unit
For finding the right window air conditioner, there are many factors to consider, such as the size of your room, the type of window you have, its orientation, energy efficiency rating of the AC, and how much insulation the unit will require.
1. Size of Your Room
Finding the right AC size is important as a large unit will struggle to remove moisture from your room, while a small unit won’t cool properly on hot summer days.
The first step is to measure your room’s size. Find out the width and length of your room, and then use this formula:
Length x Width = Area
To measure the area of a rectangular room, L-shaped room, or T-shaped room, you will first have to measure the shortest length and width of the room. Multiply them to get to the main area. Then calculate the area of the individual spaces in your room by measuring their length and width and multiplying them. Add all the areas to get the total area of your room.
2. Determine the Type of Your Window
Understanding the type of window you have is essential as window air conditioners are not designed to fit every window type.
If you have a sliding window or a casement that opens outwards, you can’t install a window air conditioner. A double-hung window in which there is an upper pane and lower pane that slides up and down is the most suitable for window air conditioners.
3. Energy Efficiency Rating of Your Window AC
For choosing the appropriate unit for your room, focusing on the right energy efficiency rating (EER) is important. A higher EER number is always better. In the case of window air conditioners, the EER rating ranges from 8 to 12. A rating of 10 or higher is considered ideal for energy conservation.
4. Window Orientation
If you are installing a window AC unit in the south or west-facing window, then it would get direct sunlight for the most part of the day. A window air conditioner, in that case, will not be able to handle the extra heat. Moreover, the intense direct light can decrease the unit’s efficiency by about 10%.
Consider installing your window AC in an east or north-facing window where it won’t get harsh sunlight.
Moreover, consider the direction of rain. Does your window receive direct rain? You can also cover your window air conditioner to protect it from rain and direct light when needed.
5. Amount of Insulation
Insulation is essential to trap cooled or heated air in your room and for protection against strong winds and rain when installing a window AC. If there are gaps around your window unit, air will escape, and outdoor air will enter the room, causing your AC to work harder and energy efficiency to decrease.
The amount of insulation required depends on the number of gaps. These can be identified by holding a candle and moving it around the AC; if the flame flickers, there is a gap. Insulation is also required in the spaces between the glass panes.
Your window AC may come with insulating foam; if not, you can easily get flexible foam for insulation. For more information on window insulation, read our guide.
Preparing For Your Window Air Conditioner Installation

Follow the guidelines below to prepare your window for a seamless installation process:
1. Clean & Inspect Your Window
Thoroughly inspect the window and make sure that it is in good condition. Check for rot or any other damages around the window frame. Your priority should be focusing on the necessary repairs. You would not want to find a problem after installing the unit.
It is also a good idea to properly clean the window as you won’t be cleaning it until after the end of the season when it’s time to remove and store the AC unit from the window.
2. Remove Obstructions Around the Window
If you have decorative items or plants on your windowsill, it’s time to remove them. You will want to clear the area as much as you can so there are no obstructions when installing a window AC unit. If you have installed a storm window frame, it’s also time to remove it as it can interfere with the overhanging part of the unit.
3. Check the Load on the Circuit
Check the load on the circuit you want to use for your window AC unit. If the other devices are also plugged in the same circuit, there are chances of tripped breakers or a blown fuse, even with a simple appliance such as a hairdryer. A separate circuit that will solely power your window AC should be added.
How to Install a Window AC Unit?

After ensuring that you have checked all the points mentioned above, it’s time to install your window air conditioner!
Firstly, take your air conditioner out of the box, of course, and gather all the equipment that you may need, such as a screwdriver, screws, brackets, measuring tape, and scissors. Next, very important, call your assistant! You’ll need an extra pair of hands for the process. Also, don’t forget to read the user manual. You will want to make sure that you do everything according to your window AC installation guide.
