How to Install a Portable AC in Your Casement Window: A Step-by-Step Guide

If you live in a space with casement windows, you might be wondering how to install a portable air conditioner to keep your home cool during the warmer months. Casement windows, also known as crank windows, can make installing a portable AC unit a bit more challenging than with traditional windows. However, with the right tools and a little bit of know-how, you can successfully set up your portable AC in no time. In this blog post, we'll walk you through the process step-by-step, so you can enjoy a comfortable and cool living space.

Step 1: Choose the Right Portable AC Unit

Before you can install your portable air conditioner, you'll need to choose the right unit for your space. Consider factors such as the size of the room, the number of windows, and your budget when making your decision. Be sure to measure the dimensions of your casement window, as you'll need this information when selecting an AC unit and purchasing the necessary installation accessories.

Step 2: Gather Your Tools and Materials

To install a portable AC in a casement window, you'll need the following tools and materials:

Portable air conditioner

Casement window installation kit (specific to your AC unit)

Measuring tape

Screwdriver

Drill (optional)

Weatherstripping or foam insulation

Plexiglass or plywood (optional, for custom window insert)

Step 3: Prepare the Window

First, clean your casement window and remove any screens, if necessary. Next, open the window fully to ensure you have enough space to install the AC unit. If your window opens vertically, you may need to install a support bracket to hold the window open and prevent it from closing on the AC unit.

Step 4: Install the Window Insert

The window insert is a crucial component of your portable AC installation, as it will hold the exhaust hose in place and seal the window opening to prevent warm air from entering your home. Most portable AC units come with a window installation kit that includes a window insert designed for traditional windows. However, you may need to purchase a casement window installation kit separately, or create a custom insert using Plexiglass or plywood.

To install the window insert, follow the instructions provided with your casement window installation kit. Typically, this will involve attaching brackets or clips to the window frame, then sliding the insert into place. Be sure to measure the width and height of your window opening to ensure a proper fit.

Step 5: Attach the Exhaust Hose

Once the window insert is in place, attach the exhaust hose to the portable AC unit according to the manufacturer's instructions. Then, connect the other end of the hose to the window insert. Make sure the hose is not kinked or twisted, as this can reduce the efficiency of your air conditioner.

Step 6: Seal the Window Opening

To prevent warm air from entering your home and reduce energy loss, it's essential to seal the window opening around the window insert and exhaust hose. Use weatherstripping or foam insulation to fill any gaps and create an airtight seal.

Step 7: Plug in Your Portable AC Unit

With the window insert and exhaust hose in place, plug your portable air conditioner into a nearby electrical outlet. Make sure the unit is positioned on a level surface and has adequate ventilation.

Step 8: Test Your Portable AC

Turn on your portable air conditioner and set it to your desired temperature. Allow the unit to run for a few minutes, then check the window insert and exhaust hose for any air leaks. If necessary, adjust the window insert or add additional weatherstripping to improve the seal.

There you have it – a comprehensive guide to installing a portable AC unit in your casement window. With these steps, you can now enjoy a cool and comfortable living space during those hot summer months. Remember to maintain your portable AC unit by cleaning the filters regularly and storing it properly during the off-season to ensure it stays in top condition for years to come.

Why choose the tilt and turn opening method?

Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.
