What is a casement aircon?

For small rooms with casement windows that swing outward—one half to the left and the other to the right—a casement aircon is an excellent and cost-effective cooling solution in Singapore. It is commonly known as slider or vertical aircon. It is specifically designed for such window types and has become a popular choice among Singaporean flat-owners. Its sleek and visually appealing design perfectly complements narrow sliding windows without a center frame, offering both functionality and style.

Is a casement aircon the same as a window aircon?
Although both are great options for cooling small rooms, the casement and window-type aircons are two different types of standalone air conditioning units. A window aircon has a boxlike and wider design. A casement aircon, on the other hand, is taller and narrower. It perfectly matches the dimensions of the casement window it is designed to fit into. In terms of installation logistics, window aircons rely on the window sash (and also support brackets) for stability, while casement aircons already come with an aircon installation kit. The kit readies them for mounting onto casement windows. All in all, the lack of window sash in casement windows necessitates more work when installing casement AC units–which translates to increased installation costs.

Do you need a roof or a shelter for your casement air conditioner?
Like a traditional window aircon, the outer half of a casement aircon can withstand harsh outdoor conditions. Still, it is advisable to shield this portion of the aircon from direct sunlight and rain. Direct exposure to the sun’s heat can make the aircon work harder, leading to increased energy consumption and higher electricity bills. Over time, this added strain can result in faster wear and tear on the unit. By simply installing a small roof or awning, you can protect the aircon from direct sunlight and help extend its lifespan.

What are the main advantages of a casement aircon?
The major advantage of a casement air conditioner is its quick, installation-ready configuration. Its ease of installation to cool a small room, as well as its beautifully sleek fit onto the casement window of your HDB flat, makes it a perfect budget-friendly choice.
A casement aircon needs proper installation and support. This is to ensure the unit remains secure and not end up falling. Unlike split-type air conditioning systems, which require extensive work to install, a casement aircon involves a straightforward initial setup. This setup simply requires fitting the unit into the casement window, making it a convenient and secure cooling solution.
So, if you have a small room that you can insulate, a casement aircon makes for a decent, energy-efficient choice to meet your cooling needs. Still, always check if the aircon has energy ticks to ensure good power efficiency, as well.
What are the main disadvantages of a casement aircon?
Two major drawbacks are associated with a casement aircon in Singapore. One is the painfully involved process of refilling in case the AC unit runs out of refrigerant liquid. The tedious process will involve taking the aircon out of the casement window and topping it up with coolant. Then reinstalling it. The other disadvantage is the level of noise it produces.
