With the temperature levels in India, it is imperative to have an AC. Quite too often you may find yourself wondering whether a window AC or a split AC is better. Knowing the answer to this question is extremely vital in making the right purchase decision. Doing your research can also keep you from spending unnecessarily. However, to understand the difference between split and window AC units truly, you will have to learn about more than just their price points or installation.

For a comprehensive explanation that answers the question, keep reading.

Difference between split AC and window AC

Picking either a window AC or split AC can be quite the task. It is important to know about the differences as they can affect more than just the price you pay. Here is all you need to know:


Price is the first factor that distinguishes the two, and this is why it is important to have a set budget. Depending on your budget, you can choose the type of AC to go with as it is crucial to account for installation and maintenance also. Typically, in the window AC vs. split AC price battle, a window AC is a cheaper variant for the same tonnage. This further extends to maintenance as well, as here too, the costs are lower for window ACs.

Space requirement

The most noticeable window AC and split AC difference lies in the space requirement. Window ACs generally require a large amount of space as the entire appliance is just one unit. This means you need to either designate a full window or make adjustments to a wall to accommodate the AC. However, in terms of a split AC, there are 2 separate units that can be mounted on either side of the same wall, giving you some amount of flexibility.

Energy consumption and efficiency

Simply comparing window AC vs. split AC, energy consumption numbers will not be different as similar rated units consume similar amounts of power. Further, in terms of AC efficiency, older air conditioners are not as forgiving and newer window AC and split AC models with inverter technology consume less power than their non-inverter counterparts. In the window vs split AC comparison, a lot boils down to the appliance’s BEE rating and the compressor technology employed.


A split AC is virtually silent whereas a window AC can be quite loud, even when not operating on a heavy load, as it is fitted to a window frame. Further, the compressor is responsible for most of the noise and in a window AC, the compressor, and the inner blower are one unit. This is not the case with split ACs as the inner and outer mechanisms are separate from each other. The compressor is housed in the outer unit, making it the quieter of the two.

Cooling capacity

The capacity of an AC, or its cooling ability, is based on its tonnage. However, split ACs are mounted high and designed for cooling larger spaces, whereas window ACs are better for air circulation in smaller rooms. It is also possible to get split ACs of a high tonnage, of above 2 tons.

Maintenance and serviceability

The debate between a split AC and window AC – which is best in terms of maintenance, is actually a no-brainer. Since a window AC has just one unit, the cost of maintenance is low, and it is easier to service. However, since a split AC has 2 units, it is tougher to service and requires periodic maintenance to ensure optimal results.

Frequently asked questions

What is the difference between a split AC and a window AC?

Split AC and window AC are two common types of air conditioning systems. Split AC has separate indoor and outdoor units, offering better aesthetics, higher cooling capacity, energy efficiency, and lower indoor noise. However, it requires professional installation and has a higher upfront cost. Window AC is a single unit installed in a window or wall, suitable for smaller rooms, and has easier installation and lower cost. Yet, it may be less aesthetically pleasing and noisier. The choice depends on room size, budget, and preferences, with split AC being ideal for larger areas and window AC for smaller spaces.

What are the disadvantages of a window AC?

Window ACs come with several disadvantages that users should be aware of before making a purchase decision. One major drawback is their impact on aesthetics. These units can be visually intrusive, occupying window space and obstructing both indoor and outdoor views, affecting the overall appearance of the building. Additionally, window ACs often have lower cooling capacities compared to split ACs, making them less suitable for larger rooms or multiple spaces. Installation can be a challenge, as it requires cutting a hole in the wall or window, limiting flexibility for relocation or maintenance of the original structure. Noise can also be a concern, as all components, including the compressor, are in one unit, leading to higher indoor noise levels.

Why does a window AC consume more electricity than a split AC?

Window ACs generally consume more electricity than split ACs due to several reasons. First, window ACs have all their components in a single unit, including the compressor, which can lead to less efficient cooling. In contrast, split ACs have separate indoor and outdoor units, allowing for better temperature control and energy efficiency. Additionally, window ACs might have older technology and lower energy-saving features compared to split ACs, contributing to higher power consumption over time.
