Split AC vs Window AC – Which is the Best?

Which is Better in Window AC and Split AC ?

Split AC vs Window AC, which is the best, a very common question arises when looking for an Air Conditioner. In this article, we will answer this question. 

Both of them have their positives and negatives, according to your need. It depends on what you want in your home, as many factors play an important role in deciding which is the best fit. So let’s get started without any further due.

Window AC

Window AC comes in a single unit, in which one face is installed inside, and the other is installed outside through a window. They are quite suitable for a small room with a window. That’s why we can refer to them as pocket-friendly and also has a low maintenance cost.

Split AC

The Split AC comes with multiple units, an outdoor unit(Condenser, and Compressor) and an indoor unit(Evaporator). 

It does not require windows for installation; the condenser and compressor are placed outside while the evaporator is placed inside. This AC is used for large rooms as its cooling capacity is quite high.

Split AC vs Window AC

We will now compare both the ACs and find which one will be a better choice for your home.


Split AC comes in different colors and patterns, which complements the entire look of your room. Window AC, on the other hand, offers only one color, which is white.


Installing a Split AC requires a professional means extra installation charge. Whereas the Window AC is easy to install and doesn’t require a professional.

A Window AC is compact, making it easy to move from one place to another; therefore, it is always a good decision to go for a Window AC if you live in an apartment.

Energy Efficiency

The EER (Energy Efficiency Ratio) determines the power consumption of an AC. It is the amount of cooling an AC can provide per unit/watt of electricity it consumes. Higher the energy efficiency ratio, the better is the star rating.

Split AC vs Window AC – Which is the Best
Star Rating and Power Saving Guide

The Star Rating determines the energy efficiency of an AC, and the rating is in the range of 1-Star to 5-Star.Both Split and Windows ACs are available with 5-Star ratings; however, the number of Split AC models with a 5-Star rating is higher compared to Window AC. In this case, a Split AC may be a better choice because of its wide range of models to choose from.

Cooling Power

Split AC has a higher cooling capacity, which makes it suitable for large rooms. While a Window AC looks compact and suitable for small rooms. If you are looking for an AC for a large room, think about Split ACs instead of Window ACs. Otherwise, Window ACs suit the best.

Space available

Here comes the major difference between a split ac and a window ac,

  • Window AC comes with a Single unit.
  • Split AC comes with multiple-unit, i.e., Indoor Unit(Evaporator) & Outdoor Unit(Compressor and Condenser).

Window AC requires a large window or opening for its installation. It might be challenging to find enough open space. On the other hand, a Split AC gives you the flexibility to place the outdoor unit( Compressor and Condenser) and the indoor unit( Evaporator) anywhere you find perfect. You can increase the pipes’ length, which connects the indoor and outdoor units. 

“Because of the flexibility, most of the flat owners prefer a Split AC over a Window AC.”


A Split AC is costly as compare to a Window AC. On average, the cost of a 1-1.5 TON Split AC is somewhere between 30,000 – 50,000 INR, while a 1-1.5 TON Window AC will cost you about 18,000 – 30,000 INR.

“The most expensive Window AC is Carrier Estrella 2 Ton 3 Star Window AC, which costs you around 35,000 INR.”

“The most expensive Split AC is Daikin FTXF71TV16 2.2 Ton Inverter Split AC, which costs you around 83,000 INR.”

An AC is a long-term investment; therefore, you should go for the ideal balance between pricing and efficiency.

Capacity of AC

Both ACs are available in various TON capacities, such as 1-TON, 1.5-TON, and 2-TON. 1.5-TON and 2-TON ACs are ideal for rooms in Indian Homes.

A Split AC is better at cooling a large room, while a Window AC is suitable for a small room. A Split AC cools a room faster and consumes less electricity as compared to a Window AC.

“If you are looking for a Split AC, then go for Inverter Technology, as it saves a lot of power. However, Window ACs are not available with Inverter Technology.”

Factors which affect the consumption of Electricity by an AC:

Room size

The size of the room decides the amount of air that requires cooling. The bigger the room, the higher is the capacity you need.

Furniture in the room

The fewer the furniture in the room, the lesser will be the consumption of electricity.

Population in the room

Humans emit heat from their bodies. The higher the number of people, the more is the heat generated in the place. Therefore, you will require an AC of a higher capacity.

Windows in the room

Insulating the windows can reduce power consumption as closing the windows can help to trap the cold air inside the room.

Electricity load in the room

The higher the electricity load, the more is the electricity consumption.

Walls facing the sun

If the room gets direct sunlight, it is better to insulate it before turning on the AC to reduce the AC load and save the electricity.

Delightful has gained in importance.

Compliments and beautiful design go hand in hand. Your AC is an important part of your interior decoration. A Window AC is not as attractive as a Split AC, as the Split AC comes with stylish looks, which looks better than a Window AC.

So if you are concern about the design, then a Split AC should be your first choice.


 A Split AC produces little or no noise at all, whereas window ACs produce a lot of noise. Now it depends on you, whether you are comfortable with noise or not, go for either one. 

Comfort and convenience

If you are looking to sleep without any disturbance, then definitely a Window AC is not your first choice. It makes a lot of noise while functioning. On the other hand, a Split AC does not make much noise, as the compressor and the condenser unit are located in the outdoor unit, while the evaporator unit is located in the indoor unit, resulting in a higher comfort level.


The maintenance of a Split AC is higher compared to a Window AC as it requires a servicing at a proper time interval with the help of an expert. Also, when it comes to self-troubleshooting, a Split AC is way more critical than a Window AC.

Split AC vs Window AC Final Conclusion

The above information must have cleared your doubts about a Split AC and a Window AC; both have their pros and cons. It totally depends on you what you need. 

However, a Split AC is better than a Window AC if you look at the power efficiency, cooling capacity, and design, but you have to pay a little more. Surely, it will be advantageous in the long run. It is always advisable to go for a 5-Star rating AC, as it guarantees maximum efficiency.
