Insulating your window air conditioners will help you save money on your heating bills in the winter. It helps keep the cold outside and the warm air inside. Fortunately, insulate your window air conditioner for less money and time.
In the event that you don’t insulate the perimeter of your window air conditioner, the warm air in your room will seep out of the unit. The AC’s efficiency will be lowered by rain and other precipitation that enters the building from the outside. The cost of heating your home will soar.
A window air conditioner’s greatest insulation is to follow the manufacturer’s directions for installation. First we’ll look at how to install a window air conditioner. To get the most of your window air conditioner, understand how to properly insulate it.
Things to Consider Before Installing a Window Air Conditioner
Before purchasing or installing a window air conditioner in your home, consider the following aspects.
Size of Your Room
Depending on the size of your space, you’ll require a varying cooling capability from a window air conditioner. You’ll need a more powerful air conditioner for a large room.
For a given cooling capacity, a larger room will require a more powerful air conditioner than a smaller one. Because of this, your window AC’s effectiveness and lifespan will be reduced, and you’ll end up paying more for heating.
Air conditioner cooling capacity is typically measured in British Thermal Units (BTU), which are available in a wide range of sizes. To keep a room at a comfortable temperature, an average of 20 BTUs is required per square foot.
You’ll need a 10,000 BTU window air conditioner for a 500-square-foot room, for example. Rooms of varied sizes require varying cooling capacity, as seen below.
You can find out more about air conditioner sizing in this article.
Design of Your Window
Window air conditioners come in a variety of shapes and sizes. You must first determine the type of window you have, whether it is a double-hung, a slider, or a casement. In addition, you should check the AC’s compatibility by measuring the window’s height and width.
Double-hung windows with lower sashes are ideal for air conditioning equipment. The lower sash may be lowered or raised, making it easy to put an air conditioning unit in the house. In this section, I’ll explain how to install a window air conditioner in a double-hung window
Energy Efficiency of the AC
All air conditioners use a significant amount of electricity. The Seasonal Energy Efficiency Rating (SEER) is a measure of the unit’s ability to save you money on your utility bill (SEER). The SEER rating of a window air conditioner is an important consideration when making a purchase.
When it comes to air conditioners, SEER stands for Seasonal Energy Efficiency Ratio. With 10,000 BTUs of cooling capacity and 1,000 W of power, an AC’s SEER rating will be 10. SEER ratings can be found here.
You can save money on your utility expenses by installing energy-efficient window air conditioners. Among the best is a window air conditioner that is Energy Star certified.

Because of the difficulty of installing a window air conditioner, the majority of Phoenix residents choose our air conditioning services. Ideally, it’s preferable to seek the advice of a specialist. If, on the other hand, you insist on doing the work yourself, consider the following advice.
A window air conditioner can be installed with these equipment and materials.
- A/C in the window
- Bit for screwdriver
- Measurement using a piece of tape
- use bits to drill
- Foam that acts as an insulator
With your materials and tools ready, let’s look at how to quickly and easily install a window air conditioner. Listed below are the necessary actions.
Step 1: Inspect the Window
Checking the condition of the window is a must. The AC’s overhanging component on the outside can be damaged by obstructions on your window, such as storm window screens. The AC can be safeguarded by removing or raising the screen.
You should wash the glass both inside and out as you inspect the window. Until you take out the air conditioner, you’ll most likely leave it closed. Clean the area around your window to free up additional space for work.
Step 2: Mount the Window AC Unit
You should follow the manufacturer’s recommendations while putting the air conditioner in your window. You’ll raise the lower sash of the window and place the AC in the middle of the window. Keep in mind that you’ll need a second set of hands to help you install the device.
Slide the flange at the bottom of the air conditioner so that it rests on the windowsill while keeping the unit balanced. Make sure the AC’s top flange is firmly on the lower sash of your window. Let your aide hold it for the next steps.
Step 3: Screw the AC Unit on the Window
The AC unit must be securely held in place after the window sash has been lowered. When the sash is unintentionally raised, the AC unit could fall. The upper flange of the AC can be screwed into the window sash with two or three screws.
However, you must first drill the holes before putting the screws to avoid fracturing the wood. The lower sash should be held in place by two little L-shaped brackets screwed into the top.
Step 4: Fix the AC’s Side Curtains
Curtains and frames are included in most window air conditioners. The AC unit’s side drapes need to be fixed and pulled out to the window’s margins on both sides. To ensure that the curtains stay in place, use curtain rod screws to attach them to the window frame.
A window air conditioner’s side curtains act as the appropriate form of insulation to keep hot air out of the house. Bugs are kept out of the room because of this. When it comes to putting the side curtains back in place, follow the directions provided by the product’s manufacturer.
How to Insulate Around a Window Air Conditioner
Once the device is in place, you’ll need to add extra insulation around it. That will help keep the heat in your room, especially in the winter, from escaping. Heating costs will not be as high as they could be.
To insulate a window air conditioner, follow these instructions.
Step 1: Identify Air Leaks around the AC Unit
Inspect the area around the window air conditioner after installation to make sure there aren’t any gaps that could cause issues. Inspect the perimeter of the unit to determine whether you can see daylight, and if so, apply extra insulation. Also check to see whether the AC’s accordion flaps have holes behind them.
In rare cases, the spaces around the window air conditioner may not be visible. To locate the leaks, light a candle lighter and place it next to the window AC unit. After that, go around the AC with the lit lighter.
The flame will flicker if there is an air leak near the AC unit. When you intend to keep the air conditioner running all year long, this strategy is the most effective.
Step 2: Insulate around the AC Unit
Insulate the window air conditioner with a flexible foam insulation material once you’ve found all the cracks and holes. Using a sharp knife, cut and fit the foam insulating strip into the gaps and apertures found.
The gaps between the upper and lower sash glass panes need to be filled with insulation. Insulating foam must also be inserted into the gap between the window frame and the AC unit body.
Most modern window air conditioners come with insulating strips/foams, which is a good thing. Because of this, it is necessary to purchase an insulating material for the unit if it does not already have one.
Step 3: Weatherize and Cover the Unit
Protecting a window air conditioner from the rain’s destructive effects is one of the benefits of weatherizing it. Unscrew and remove the air conditioner’s exterior cover to reveal its internal components. Make sure the unit is covered in a plastic bag before putting the outer cover back on it.
Instead, you can purchase a cloth cover that is specifically intended to fit the window air conditioner. To protect the unit from rain and snow, place the cover directly over the unit’s exterior cover. Fortunately, most hardware stores carry fabric covers.
Easiest During Installation
Installation guidelines, including the recommended insulating procedures, are the best approach to avoid air leaks around an air conditioner. In the box, look for pieces of foam insulation from an air conditioner. The bottom edge of the window sash, the part of the window that closes toward the air conditioner when viewed from the inside of the home, is where this peel-and-stick foam should be applied.
Before installing the air conditioner, cut the foam strip to the width of the window sash and adhere it to the bottom edge of the sash. You should slide the air conditioner’s two plastic accordion parts outward as far as they will go to cover any obvious gaps in the window area once you’ve completed the installation of the air conditioner. These serve to keep insects and outside air out of the house.
Air Conditioner Insulation After Installation
Make sure to add more air conditioner insulation around the unit if you can see daylight around its perimeter. The outside of the device should be checked as well if it’s easily accessible The air conditioner’s accordion flaps may not be able to keep rain out of the window area if they have large gaps surrounding them. Cut or snap the hard foam insulation board to size and use it to insulate these voids.
Foam insulation can be used to fill in the remaining gaps. Re-do the process inside, being sure to close in any openings where light is leaking in from the outside. Increase the amount of foam on top of the window sash to prevent air leaks.
Finding Air Leaks
Even though you can’t see a gap, air can still get in from the outside. A lit candle lighter near the air conditioner will help you cool down. Move the lighter along the air conditioner’s perimeter and the window sash’s borders. An air leak will cause the flame to flicker. This type of testing is especially critical if you want to put the unit in the window throughout the year to assist avoid heat loss.
Foam insulating strips can be used to fill in the gap between the AC unit and the window. Almost any hardware or big-box home improvement store carries a wide variety of thicknesses and lengths of weatherstripping.
Winter Window Unit Insulation
In cold, windy weather, your window unit can be a significant source of energy loss if it is not adequately insulated. Invest on a window unit air conditioner cover that is quilted on the outside. The outside of these covers is made of plastic, while the inside is made of quilted cloth. Covers for air conditioners should be measured before purchasing; if they are too large, they may not remain in place or restrict cold air from entering the unit.
If your air conditioner’s weatherstripping needs to be replaced, now is a good time to do it. Old windows in a home are no different. Sliding windows have noticeable air leaks that can be sealed with foam weatherstripping installed on the tops and sides.
