Reviews about Frigidaire air conditioners’ simple and quick installation as well as their high-tech features attracted your attention. You went out and bought a new air conditioner after deciding on the best model for your needs.

There is no difference between waiting for the package to arrive at your door or purchasing it from a local retailer. Your main goal now should be to reach the Arctic Circle and get out of this desolate part of the world. What do you mean by that?

You took out the instructions and started reading. Even yet, you’re left with a sense of unease and skepticism. What’s next? Not to worry! Continue reading and you’ll watch the pain fade away. That’s not it, I assure you. Freeze to death? Okay, now it’s your turn.

Before You Start

Consider the proximity of an outlet while selecting a window. The average length of the power cord for a window air conditioner is 5 to 6 feet. Check which side of the AC plug the cord comes out of, then plug it into the nearest available outlet. In addition to the manufacturer’s instructions, make sure you have your owner’s manual on hand.

Required Tools

  • Socket wrench
  • Calibration tool
  • Screws and brackets included as part of the manufacturing process.
  • Cutlery (depending on the model)

Size the Room

The cooling capacity and size of window-mounted air conditioners range from roughly 5,000 BTU to 25,000 BTU (British thermal units). Every square foot of living area requires roughly 20 BTU of cooling. A 12-by-16-foot space would require a cooling capability of 4,000 BTUs (12 x 16 = 192 sq. feet x 20 = 3,840 BTUs) for an air conditioner.

An easy-to-follow method for determining what size air conditioner you need is here. Window air conditioners in the 150-1,600 square foot size range are available in the following sizes:

It’s crucial that you pick a fan that has enough cooling power to do its job. On the hottest days, a little air conditioner won’t be able to keep the room cool. It’s just as problematic to pick a unit that’s too large, which is another typical blunder.

An air conditioner that is too large can cause dangerously high levels of humidity in a room, especially for persons who have breathing problems. Dust mites and mold love damp environments, which is why it’s important to avoid it. Additionally, a larger air conditioning unit is noisier and more energy-consuming than a smaller model.

Step 1: Remove Your AC and Find the Center of Your Window

Removing it from the packaging should be done with caution to prevent damage. The unit’s backside can be dangerously sharp.

Take everything out of the box to make sure it arrived in one piece. Once you’ve determined the width of your window, make a pencil mark in the middle of it. Installing the side panels will be easier and more uniformly distributed if you mark the spot where they will be attached.

Step 2: Open and Prepare Your Window

Open your windows. Install a weather strip if one was provided by the manufacturer. When you’re installing or removing the AC, these strips assist safeguard your window by blocking any air that might get through small crevices.

If you don’t have one of these weather strips, your air conditioner will still work.

Step 3: Attach the Side Panels

On your device, slide in the panels. Make sure they’re all the way in, and then screw the adjustable panels into your window air conditioner with the included screws.

You don’t want any gaps in your insulation, which can allow heated air, allergens, and pollutants to get into your house.

Step 4: Insert Your AC in the Window

Use two persons for this step if you can. Closing the window and locking the AC are safer with an extra set of hands, even if you can lift it yourself.

Get your air conditioner and place it in the window. You should be able to simply move your window into place once you’ve closed it tightly on top of the AC.

If you’re going to lift the unit, you’ll want to do so with caution. Your air conditioner should be safely installed once you’ve closed the window.

Step 5: Install L Brackets

Finally, the hard work is done. You’re about to wrap things up and secure everything. Installing windows can vary depending on the manufacturer, but most come with a L bracket to keep them in place.

Attach the L bracket or brackets to the open window’s top with wood screws or bolts or nuts. When window ACs are installed, the primary fear is that they will be pushed up.

It’s strongly recommended that you use one of your own tools to hold your window in place if your AC doesn’t come with a bracket.

Step 6: Attach Panels

The window padding can be added to both sides of an open window if it is provided (top picture above). Extend the side panels to reach your window if you don’t have padding in your model (bottom picture above). Then, using screws provided by your manufacturer, secure the two side panels to your window.

Step 7: Secure Unit and Start Cooling

A few manufacturers include mounting brackets and screws for attaching the air conditioner to the window sill on the inside of the vehicle. Some manufacturers don’t think it’s vital to have this extra layer of protection. Screw them in now if they’ve been provided.

There you go! Turn on your air conditioning by plugging it in. Your room should start to feel cooler right away.

Buy the Best

You’re in luck if you’re in the market for a new window air conditioner.

The rivalry to sell these appliances has been fierce recently, with statista.com and the U.S. Department of Energy reporting sales ranging from 1.74 million to 5.4 million in a single year.

Manufacturers compete to lower pricing and add features like voice control, app control, hand-held remotes, timers, as well as features like a dehumidifier setting, so you benefit from that competition. Aside from all the extra bells and whistles, modern appliances are more environmentally friendly than their predecessors.

Check Your Window

Air conditioners for double-hung windows are the most common, although they can also be installed in sliding or swing-out casement windows. The air-conditioner manufacturer may have unique installation instructions for you to follow.) Here, I’ll explain how to install double-hung windows, which are the most popular type of window.

Consider Energy Efficiency

With an EER number, you can tell how efficient a room air conditioner is, which stands for Energy Efficiency Rating. A unit’s EER rating is determined by dividing its BTU output by its wattage output. An air conditioner that uses 1,200 watts of power to cool a room with 12,000 BTUs has an EER of 10.

Typical window air conditioners are rated between 8 and 12. If you want to save money on your utility bills, a rating of 10 or above is preferable. Consider options like digital temperature controls, variable fan speeds and sleep settings that can save energy.


Two workers are required for the installation of a window air conditioner. Even the smallest air conditioners are difficult to move because of their weight and size. And the last thing you want is your air conditioner to tumble out of the window or onto the ground.

Begin by reading the instruction manual and familiarizing yourself with all of the hardware and fasteners that come with the product. Adjustable window extensions and metal mounting brackets are typically included in the standard installation kit that most units ship with. To create a tight and airtight seal, these pieces are required. Additionally, a steel support bracket can be purchased and mounted right below the windowsill on the outside of the house for larger air conditioners.

The A/C unit should be centered on the windowsill after raising the window bottom sash. Be sure to have a strong grasp on the device, as most of the weight will be dangling out the window. When you’ve reached the top of the A/C unit, pull down on the bottom sash until it touches the metal flange running across the unit’s top. Keep the lower sash in place; it’s preventing the unit from falling out the window. Small metal brackets called L-brackets are often included in the installation kit to keep the lower sash from being raised.

Brackets should be attached to both the lower sash and to the left, top edge. Then, screw the bracket to the upper sash with a cordless drill. Install the final bracket on the far right side of the lower sash by repeating the previous step. The metal flange extending across the top of the A/C unit may additionally necessitate short screws being driven into the lower sash. The A/C unit is safe once the brackets are fitted in and the lower sash is fastened in place.

to the window jambs of each addition. Using the thick foam-rubber weatherstripping, shove it into the space along the upper sash to keep bugs and hot air out.

When properly installed, the A/C unit will tip slightly to the outside. This is important to allow condensation to drip outside, not into the room.

Power It Up

Air conditioning units that are properly mounted tip slightly toward the outside. In order to prevent moisture from dripping into the room, this is essential.

To ensure that the air filter is clean and clear of obstacles, check it every month during the cooling season.

Removal for Storage

Removing a window air conditioner unit can be a hassle, so leave it in place and cover it with a slip-on cover unless you absolutely must have access to the window or want to improve the seal for the winter.

With two people, it’s advisable to remove the air conditioning unit. To begin, reverse the installation process, but be extremely cautious not to remove the two small L-shaped brackets until the air conditioner has been pulled into the room far enough so that it rests securely on the ledge and is not tipping in or out.
