Split AC Vs Window AC – Which One To Choose

Choosing between Split AC vs Window AC? When it comes to choosing an air conditioning system for your space, the decision between a Split AC and a Window AC can be quite the puzzle. Both options have their own set of advantages and considerations that need to be weighed. In this article, we’ll delve into the factors you should consider when making this important cooling choice.

1. What is the Difference between Split AC and Window AC

Split AC and window AC are two common kinds of air conditioners. A split AC has two parts, one inside and one outside, which makes it look better, cools well, saves energy, and doesn’t create much indoor noise. But, it needs a pro to set up and costs more initially. A window AC is just one unit that fits in a window or wall, good for small rooms. It’s easier to install and costs less, but it might not look as nice and can be louder. Picking between them depends on how big the room is, your budget, and what you like. If your space is big, go for a split AC; for smaller areas, a window AC is a good pick.

2. Aesthetics

When it comes to looks, split ACs and window ACs have their differences. Split ACs have a sleek appearance since the indoor unit can be mounted high on a wall, blending well with your room’s design. The outdoor unit can be positioned outside, maintaining the overall aesthetic.

On the other hand, window ACs might not be as visually pleasing. They need to fit into a window frame or a hole in the wall, which can be noticeable and impact the appearance of the room. Additionally, window ACs might obstruct the view from the window.

So, if aesthetics are important to you, split ACs usually have the upper hand. They offer a more seamless and modern look compared to window ACs.

3. Ease of Installation: Split AC vs Window AC

Installing split ACs is quite easy. You only need a small 3-inch hole to connect the indoor unit (IDU) to the outdoor unit (ODU) through pipes. This hole is hidden behind the IDU, so everything looks neat. On the other hand, window ACs need a bigger hole, larger than the AC itself, to fit the whole AC in for support. This might be a problem if you’re renting a house, as your landlord might not agree to it. Split ACs make things simpler.

The best part about having a Split AC is that you can put the indoor unit quite far within the limits set by the company. Those limits are good, so there’s nothing to worry about.

3. Cooling Capacity: Split AC Vs Window AC

Split AC: Generally, split systems offer higher cooling capacity and efficiency. They can cool larger areas more effectively and maintain a consistent temperature throughout the space.

Window AC: Window units are better suited for smaller rooms. They might struggle to cool larger areas efficiently, and the temperature distribution could be less even.

4. Energy Efficiency: Split AC Vs Window AC

Split AC: Split systems tend to be more energy-efficient due to their advanced technology. The separate indoor and outdoor units allow for better control over cooling, resulting in reduced energy consumption.

Window AC: While modern window units have improved in terms of energy efficiency, they might not match the efficiency levels of split systems.

5. Space Requirement

One key difference between window ACs and split ACs is how much space they need. Window ACs usually take up a lot of space since the whole unit is just one piece. This means you have to use an entire window or modify a wall to fit the AC. On the other hand, with split ACs, there are two separate units that you can install on opposite sides of the same wall, providing you with more flexibility.

6. Noise Level: Split AC Vs Window AC

Split ACs are almost silent, while window ACs can be quite loud. This is because window ACs are put in windows. Most of the noise comes from the compressor. In window ACs, the compressor and inner blower are together in one part. Split ACs are different because they have separate parts inside and outside. The compressor is in the outside part, which makes it quieter compared to window ACs.

7. Price: Split AC Vs Window AC

Price is often a big deal for most buyers. While we mention it last, it’s often a major factor. We think quality should come first, and cost should be secondary. Investing once in a good air conditioner that lasts for years is better than saving money upfront by getting a cheap AC.

Normally, when comparing the prices of window ACs and split ACs, window ACs are cheaper for the same cooling capacity. This also applies to maintenance, where the costs are lower for window ACs.

8. Maintenance: Split AC Vs Window AC

When comparing maintenance between a split AC and a window AC, the answer is clear. Window ACs have only one part, so they’re cheaper and easier to take care of. But split ACs have two parts, which makes them a bit harder to maintain and they need regular check-ups to work well.

9. Why Window AC Consumes More Electricity than Split AC?

A window AC tends to use more electricity than a split AC because of several reasons. Firstly, all the parts of a window AC are packed into one unit, including the compressor. This can make the cooling less efficient. On the other hand, split ACs have separate indoor and outdoor units, which helps with better cooling and using less energy. Also, window ACs might use older technology and fewer energy-saving features than split ACs, which can make them use more power over time.


In the battle between Split AC and Window AC, there’s no one-size-fits-all answer. Your choice should be based on the specific requirements of your space, your budget, and your aesthetic preferences. If you’re cooling a larger area and prioritize energy efficiency, a Split AC might be your best bet. On the other hand, if you’re looking for a budget-friendly option for a smaller room, a Window AC could be the way to go. Consider the factors mentioned above, and make an informed decision to keep your space cool and comfortable during the hottest days of the year.
