How To Install An Air Conditioner With & Without Brackets

How To Install An Air Conditioner With & Without Brackets

To beat the tormenting heat in summer, installing an air conditioner is essential. It can feel excruciatingly painful on hotter days if you live in a closed-off room where only a little amount of air can pass through. Lesser air means you will feel hot and stuffy. Therefore to prevent yourself from the torture, installing an air conditioner seems a plausible solution. Depending on the type and space of your house, you can choose air conditions that will fit your criteria.

There is more than one type of air conditioner in the market, so it gives you the benefit of choosing the best one according to preference. Today, we will be talking about window air conditioners, also known as room conditioners. This is your traditional AC where you mount it on the windows or walls. It is a single unit that is assembled in a case with all the machinery components fit together. There are two ways on how to install an air conditioner: With brackets and without brackets. We will be discussing both of them.

Mounting a window AC in a sliding window (with brackets)

What you will need:

  • Screws and brackets
  • A measuring tape
  • A Screwdriver
  • A cutter or a scissor
  • A pencil

Step 1

Remove the components carefully. Measure the length and width of the window you are going to mount the AC on. Use a pencil or a marker to mark the center; this helps keep tabs on measurement and thus ensure the side panels are evenly placed.

Step 2

Now, open your window. Many AC manufacturers provide an adhesive strip called a weather strip to prevent air, moisture from passing through tiny holes and cracks. It also helps protect your window from potential damages due to installation. If the strips don’t come with your AC, it’s fine too.

Step 3

Slide the side panels carefully into the unit and secure the adjustable panels into your AC with the help of screws. Screw them tight to prevent air, allergens, moisture, etc., from entering inside.

Step 4

It’s better if you have people lifting your AC and fitting it onto the center of your window. After you have positioned it properly, tightly close your window on top of your AC. You should place your AC in such a way that most of its weight is shifted outside. Put screws and secure the setting.

Step 5

It depends on the manufacturers as to how many brackets they include for window AC installations, but most ACs now come with at least two L-shaped brackets to hold the window in place. Screw the brackets to the top of the opened window to prevent the window from being pushed up. If you don’t have brackets, you can either buy some or follow our no-bracket AC installation procedure.

Step 6

After you are done with all the securing, it’s time to add the padding. Use the padding to both sides of your open window. If you have no padding with your AC, extend the side panels to reach your window and attach them using screws. And you are done!

Mounting a window AC in a window (without brackets)

You have realized that the AC you have bought at a lower price is actually meant for double-hung windows, but yours is vertical. Now you are stuck but still want to make a way of using the AC, right? And the AC doesn’t have any bracket or side panels, so what to do? There is always a way!

What you will need:

  • Lumber
  • Screws
  • A drilling machine
  • Plywood
  • A saw
  • A screwdriver
  • A pencil or a marker

Step 1

Measure the width and height of your conditioner. While measuring, include any vents that stick out. The height should be measured by the box height and not the lips. Now, measure the height of the window opening. For proper measurement, start taking measures up against the window.

Step 2

Cut the framing lumber according to the height and width you have previously measured: 3 equal-sized lumber for width and 2 for height. Lay a shorter piece down and screw the ends of the longer pieces to form a rectangular frame. A good rule of thumb is to put the frame into the window opening to ensure the fitting.

Step 3

Now place the AC into the frame with the bottom lip against the outer frame. The top lip is U-shaped with a shorter backside. Make sure the placement is perfect, or else you would risk damaging the structure or the window. When you are happy with the placement, lay a lumber piece, and mark its position on the frame. Mark the topmost edge of the front lip and bottom lip as well. After you have the correct placement, remove the AC from the frame, and screw the lumbers together.

Step 4

Now measure the opened space on top of the frame. Cut a wide plywood plank according to the measurements and cover the space. You can use weather strips at this point to cover any holes or cracks. Next, open the window and slide it against the window framing. Use long screws through the wooden frame and pin the frame around the window opening. After you are satisfied with screwing the frame, it’s time to put the AC into place and add a few more screws to hold the AC’s position. 

And that’s how to mount an air conditioner in a window. Indeed, mounting an AC isn’t a single person’s job, so make sure you have at least three people to help you out. If you are scared of messing it up, you can hire professionals to handle this out.
