Split vs Window ACs: A comparative view and how that affects YOU

Buying an AC is a long-term investment. And once you’ve decided to buy; ‘split or window AC?’ is the first question you should ask yourself… or Google. Here’s a comparative look at split vs window ACs and how these differences affect your decision making.



If you just want to cool off occasionally without spending much, a window AC is a good option to go for.

But if you want a ‘wholesome’ experience with savings, reliability, features and optimum cooling you’ll be better off with a split AC.

Comparing Split AC vs Window AC

Energy efficiency

Inverter ACs (both split and window) help you save up on your electricity bills. But between a split and a window AC, split ACs consume lesser energy in general and are hence more energy efficient.

How energy efficient an AC is, is closely tied to its cooling performance. If the AC cools well, you’ll turn it off in half an hour.

But if the AC’s cooling performance is not as efficient, your usage will add up to hours. Which means higher light bills.

Inverter compressor is another aspect that affects the AC’s power consumption. Inverter compressors work at different speeds which enables them to work without sucking much energy.

Winner: Split AC

Cooling Performance

Split ACs cool better than window ACs. This is because split ACs don’t just cool the air but also circulate it effectively in the entire room.

Inverter split air conditioners are the best ACs out of all because of their reliable and consistent performance.

Window ACs, are by no means, poor air coolers. They can cool as well as split ACs (especially if its an inverter window AC).

But as window ACs are installed in windows, their location can restrict optimum air flow. As a result, you may find ‘hot’ and ‘cold’ spots in the room. The area near the AC feels ‘too cold’ while the area furthest from it might not be cool enough.

This issue can be solved by running the fan along with the AC, but it will just push your electricity bills higher.

Split ACs, on the other hand, come with features and modes that support effective circulation of the cool air. And if you buy an inverter split AC, you can enjoy uniform temperature while the AC is on.

What this means, if you’ve set the temperature to 24oC, the AC will maintain that temperature without fluctuation.

Non-inverter ACs, however make you keep the remote close by as the air can get too cold or too warm for comfort. Its because the compressor switches on and off while the AC is on.

Hence when the compressor is ‘on’ the air can get too cold before the AC detects it and switches off the compressor. Similarly, the air can feel too warm before the AC detects it and switches on the compressor for cooling the air.

Winner: Inverter Split AC


Window ACs are more affordable than split ACs, making them a better option if you’re on a tight budget.

If you’re only worried about the upfront costs, then window AC is definitely more economical. This is owing to their compact size, single unit body and limited features.

Split ACs, although more expensive than window ACs, justify their price tag with innovative features, energy efficiency and more efficient cooling. If you’re able to stretch your budget even by a few thousand Rupees, consider buying a split AC over a window one.

Winner: Window AC


Features like timer, sleep mode, advanced air filters and so on, make split ACs more valuable than window ACs.

Some window ACs (especially the newer models) do offer basic timer and cooling modes. But most come with limited features.

Split ACs, however offer a wide range of features like LED display, night-view, swing modes, cooling modes and many more. Some of these become a part of your daily routine and add on to the AC’s value.

Winner: Split AC


Split ACs are quieter than window ACs and are ideal for sensitive sleepers.

It is the compressor of the AC which makes noises while turning on and off. Since window ACs are attached almost in the house, the noise is quite audible, especially in the quite of the night.

Split ACs have a natural advantage in this aspect, as the compressor’s noise is muffled by the unit stored outside the window. Some noise is also absorbed by the windows and the walls.

Inverter ACs use a slightly different compressor which doesn’t keep starting and stopping while the AC is on. Hence the noise is cut at the source itself.

Winner: Inverter Split AC


Window ACs are compact compared to the bulky, 2-unit model of split ACs. Their compact build makes window ACs more suitable for equally compact Indian bedrooms.

Optimum space utilization, is any home maker’s main goal when it comes to managing Indian homes.

Window ACs snugly fit into any window and are perfect for small bedrooms or study rooms. Split ACs, however need more space both inside and outside the house for its internal and external unit.

Winner: Window AC


Window ACs are easier to install compared to split ACs.

Split ACs require ducting, voltage check and expert technicians to successfully install the internal and external units. Window ACs at most may require a carpenter to close the side gaps between the window sill and the AC’s edges.

If you’re never owned a split AC before, your house will need some prior preparation before you even consider buying one. For example, you’ll have to find the right spot to install the split AC, and ensure there’s an electric point with necessary voltage range nearby.

There must be ample space to place the split AC’s external unit outside window, in the balcony or any suitable space outside the house. But you must also make sure the distance between the internal and external unit is not too much.

And if all this works out, there’s also the ducting that needs to be taken care of. Phew!

Window ACs don’t have so many demands. A simple spot in the window is enough for them. Just ensure there’s a suitable electric point nearby and there are no gaps between the window and the AC.

Winner: Window AC

If you look at all the factors above, settling on any one type of AC becomes difficult. Both have strong points in their favour and against them.

So then how to decide which one will be right for you? Well, worry not!

The answer is just below!

Should you go for a split AC?

During this time when seasons seem to alternate between ‘hot’, ‘hotter’, hottest’, split ACs offer a breath of cool air!

If you want more than ‘just cool air’, split AC is the way to go. With a few extra thousand (compared to window ACs) you can ensure long-term savings, better cooling, and durability.

Even the limitations like complex installation, bulky units and higher cost can be dealt with.

Installation set-up like ducting and so on is a one-time thing. If you have fewer windows in the house then having a bulky split AC is actually a better option.

And the benefits of split AC easily outweigh its high cost and installation.

Also split ACs make the best living room ACs out of all and are ideal for large master bedrooms.

If your main purpose of buying an AC is to get rid of the sticky, hot feeling when you come home, a window AC is more than sufficient to do that.

It is only when you want more out of your AC like long term savings, and efficient cooling should you consider a split AC over a window one.
