How to Install a Window Air Conditioner: A Comprehensive Step-by-Step Guide

Window-type air conditioners are a great way to cool your home without spending a lot of money. If you’re thinking about installing one, this comprehensive step-by-step guide is for you! In this guide, we will walk you through the entire process from start to finish.

While it’s always best to consult the professionals at Air Conditioning Installation Repair Oakville, we’ll explain what tools you need and give you a simple overview of the installation process, plus some troubleshooting tips. Let’s get started!

Preparation

Before getting to work, it’s essential to take a few preparatory steps. First, make sure that the window you’re using is in good condition and can support the weight of the air conditioner.

The opening should also be at least 24 inches wide and 18 inches high.

If your window doesn’t meet these requirements, you may need to modify it before installing the air conditioner. You can either do this yourself or hire a professional to do it for you.

Another thing to remember is that most air conditioners require an electrical outlet nearby to function correctly. Make sure there’s an outlet within reach of the window where you plan to install the unit.

Tools You Need

Now that you’ve prepared the window, it’s time to gather the tools you’ll need for the installation. While these tools may differ from one AC model to the other, here’s a general list of what you’ll need:

  • A screwdriver
  • A drill
  • A level
  • Measuring tape
  • Manufacturer screws and brackets
  • Caulking
  • Scissors
  • Foam weatherstripping

Installing the Slide-in window Air Conditioner

With all the preparation out of the way, it’s finally time to install the air conditioner!

Window air conditioners come in two main styles: “slide-in” and “window frame.” The slide-in style is designed to fit into an existing window frame, while the window frame style requires that you build a new frame for it.

For this guide, we’ll be using the slide-in style. If you’re using the window frame style, consult your manufacturer’s instructions for more specific installation instructions. Here are the five easy steps to installing a slide-in window air conditioner:

1. Measure the window

Start by measuring the width of the window. Most air conditioners are designed to fit windows at least 28 inches wide.

If your window is broader than that, you’ll need to block off part of it so that the AC unit can fit snugly into the opening.

You can do this by installing a piece of wood or metal across the bottom part of the window. Just make sure that the material you use is sturdy enough to support the weight of the AC unit.

Measure and cut the wood or metal to size, then use screws to attach it to the window frame.

Once you’ve blocked off the bottom part of the window, it’s time to measure the height.

Most air conditioners are designed for windows at least 18 inches tall, but some units may require a taller opening.

If your window isn’t tall enough, you’ll need to extend the frame by adding pieces of wood or metal to the sides. If your window is already tall enough, you can skip this step.

2. Install the brackets

The next step is to install the mounting brackets. Most air conditioners come with two mounting brackets that need to be attached to the sides of the unit.

Some models may have more or fewer brackets, so consult your manufacturer’s instructions for specific instructions.

The location of the mounting brackets will vary from one AC model to another, so you’ll need to look at your unit and determine where they should go.

Once you’ve determined their location, use a drill to attach them securely to the sides of the AC unit.

If your air conditioner doesn’t come with mounting brackets, you can purchase them separately from the manufacturer or any hardware store.

Note: Some manufacturers recommend installing the mounting brackets before placing the AC unit in the window.

If this is the case, consult your manufacturer’s instructions and install the brackets accordingly.

3. Position the AC unit on the window

After the brackets have been installed, the next step is to place the AC unit in the window.

Start by tilting the top of the unit out of the window, then lift the bottom part and slide it into the opening.

Once it’s in place, tilt the top part back into the window and ensure that the unit is level. If it isn’t, use shims to level it out before proceeding to the next step.

4. Secure it with screws

Now that the air conditioner is in place, it’s time to secure it using screws or nails. Most units come with four or more holes on each side that need to be aligned with the mounting brackets.

Once they’re aligned, use a drill or screwdriver to secure them in place. Be careful not to over-tighten the screws, or you may damage the AC unit.

If your air conditioner doesn’t have holes, use nails or screws to attach it directly to the mounting brackets.

Note: Make sure that the screws or nails are long enough to go through the window frame and into the wall behind it. You can also use a drill to make holes in the window frame if necessary.

5. Plug it in

The final step is to plug in the AC unit and turn it on. Most units come with a power cord that needs to be plugged into an outlet. Once it’s turned on, adjust the settings to your liking and enjoy the cool air!

Note: The above is just one example of installing a window air conditioner. Some units may require slightly different installation procedures. Always consult your manufacturer’s instructions for specific instructions.

Air conditioner troubleshooting tips

To ensure that your air conditioner runs smoothly, you should follow a couple of essential troubleshooting tips. Here are some of them:

AC not turning on

If your air conditioner isn’t turning on, you should first check the power cord. Make sure that it’s plugged into an outlet and that the outlet is working properly.

If the cord looks damaged, replace it with a new one. If the outlet is working, but the air conditioner still won’t turn on, there may be a problem with the unit itself.

AC not cooling

Air conditioners are made to cool your space, so if your air conditioner isn’t cooling properly, there are several things you can do to troubleshoot the issue.

First, make sure that all filters are clean and free of debris. If they’re dirty, clean them according to your manufacturer’s instructions and see if that fixes the problem.

If the filters are clean and the air conditioner still isn’t cooling properly, check the thermostat to make sure it’s set to the correct temperature.

If it is, there may be a problem with the air conditioner itself, and you’ll need to call Air conditioner repair Burlington for some help.  

AC leaking water

Leaking water is never a good sign, so take action right away if your air conditioner is leaking water.

First, make sure that the unit is turned off and unplugged. If there’s still water coming out of it, use a bucket or container to catch the water and then call a professional for assistance.

If the unit isn’t plugged in, there may be a problem with the wiring. Call a professional to check it out and see if they can fix the issue.

Strange noises

When your air conditioner is making strange noises, there’s probably a problem with it, and you should call a professional for assistance.

Some of the most common causes of strange noises are dirty filters, clogged drains, or problems with the compressor.

No matter what the issue is, don’t try to fix it yourself. Leave it to the professionals, and they’ll be able to diagnose and fix the problem in no time!

Final Thoughts

Installing a window air conditioner is a relatively simple process, but it’s always best to consult your manufacturer’s instructions for specific instructions.

If you have any problems with your unit, don’t hesitate to call a professional for assistance. With proper care and maintenance, your air conditioner will keep you cool and comfortable all summer long! Thanks for reading!
