Casement windows are a nice touch for any home, especially in kitchens and bathrooms. However, for rooms lacking traditional windows, it can be a challenge to cool them with a regular window air conditioner.
The answer: Casement window AC units.
What are Casement Windows?
Casement windows are windows that are hinged on the side, and which open outwards through a crank handle. Compared to most other windows, a casement window can be opened all the way. This makes them a popular option for rooms that require higher ventilation, such as kitchens and bathrooms.
Casement windows also offer other advantages, including:
Higher airflow
By opening outwards vertically, casement windows naturally create a flap that catches more air and directs airflow into the room. You can even control the amount of breeze by adjusting the window angle.
Better aesthetics and More light
Since casement windows lack frames in the middle of the glass, they look better and provide an obstructed view of the outside. This also lets in more light, similar to picture windows. Unlike picture windows however, casement windows have the advantage of being opened.
More energy-efficient
Compared to sash windows, casement windows have stronger seals. Because they lock at several points in the frame, they are more airtight, minimizing any air gaps or heat leakage.
More accessible
Some areas are difficult to reach, such as the space above kitchen sinks or high up in shower stalls. Casement windows are a convenient option in such spaces thanks to its crank handle.
What are Casement Window Air Conditioners?
As the name suggests, a casement window air conditioner is specifically designed to fit casement windows.
Traditional window air conditioners have a rectangular shape with more width than height. While some offer accordion seals to fit sash windows, they are still an ill fit for casement windows since it will leave a large gap vertically.
Casement window ACs are narrower in shape. They are made to fit windows that swing out vertically, and are at least 20 inches in height. They may also come with precut window inserts to fit most casement window designs.
Casement Window AC vs Other Window Air Conditioners
It can be easy to confuse casement ACs with other types of window AC units. Here are the differences:

Casement AC vs Portable AC
Some homeowners opt to use portable air conditioners instead of casement window ACs.
The difference between the two is that portable ACs typically sit on the floor. They may either be vented (which requires an exhaust hose going out to the window), or ventless, which are less efficient but don’t require any windows to vent the exhaust.
The advantage of portable ACs is that they allow the casement window to remain unobstructed. They are also expensive and cheaper to install. However, portable ACs take up floor space, particularly vented models that require a hose and need to be placed closer to the window.
How to Choose a Casement Window AC
1. Determine the window dimensions
All casement ACs are less than 15” wide. However, you need to take into account the crank window installation kit, which can add an extra inch to the total width.
Manufacturers typically provide a minimum window width in the specs sheet. The industry standard is 15 ½” minimum window width. Make sure the AC’s specified minimum window width and maximum window height falls within your casement window dimensions.
2. BTU sizing
The cooling capacity of all AC units are measured in BTU (British Thermal Unit). While standard window ACs can go up to 15,000 BTUs, casement window ACs have a typical upper capacity of 8,000 to 10,000 BTUs owing to their narrower design.
Use our BTU calculator to determine the required capacity for your particular room.
3. EER
EER stands for Energy-Efficiency Ratio, which is a measure of energy efficiency derived by dividing the BTU with the wattage. The higher the EER, the more energy-efficient the unit is..
