Split AC vs. Window AC: Which One Is Better?

We will also answer the question: does window AC consume more electricity than split AC and help you decide which aircon you should buy based on your needs. We will also compare electricity consumption in split AC and window AC, along with design, installation, and price differences, which can help you make an informed choice.

What Is the Difference Between Window and Split Air Conditioner?

• In simple words, a window AC is a compact air conditioning unit that has the compressor, condenser, and evaporator all in one single box. This type of AC is typically installed in a window or an opening in your wall.

• A split AC has two separate units: an indoor unit (which blows cool air into your room), and an outdoor unit (where the compressor and condenser are placed).

So, when you compare split AC and window AC, you are comparing a system that splits its parts and functions vs one that puts everything in one place. There are advantages and disadvantages to both types, depending on the room size, noise level, and intended usage. 

Construction and Design Differences

This table will help you understand the key design and construction differences between a window and a split AC. 

These design differences tell you how each type of air conditioner performs. In many aspects there is an advantage of split type aircon vs, window type in cooling, noise, and space.

Installation Process

• The installation of a window AC is generally simpler. The technicians have to fit the unit into a window or wall opening. It requires a secure base, some structural support, and ideally, good sealing around the unit to prevent warm air leaks. 
   
   

• Split AC installation can be more complex. The technicians will need to make proper placements of indoor and outdoor units, piping, drainage pipes, electrical wiring, and insulation, and sometimes mount the outdoor unit on brackets or platforms. This leads to higher installation costs and sometimes more work (drilling or wiring).

So, when looking at the comparison of split AC and window AC in terms of ease of installation, the window AC does better for smaller setups.

Cooling Mechanisms

• Both types mainly use refrigeration cycles for cooling: compressor, condenser, expansion, and evaporator. However, their effectiveness can vary from machine type to machine type.

• A split AC separates components. Hence, the indoor unit can focus on blowing cool air without the heat and mechanical noise of the compressor. This generally gives faster cooling and more comfort.

• In a window AC setup, everything is in one box, which means the compressor’s heat (even though it is thrown outside through vents) can affect the surrounding environment. Also, airflow can be less even in larger rooms.

Therefore, in terms of cooling difference between window and split AC, split units tend to perform better (especially for medium to large rooms) in both speed and uniformity of cooling.

Power Consumption

This is a key area when comparing electricity consumption in split AC and window AC. 

• Energy Efficiency Ratings: In India (and many other countries too), ACs have star ratings (BEE star rating in India) or similar metrics that measure the power efficiency. A high-star split AC (especially an inverter type) will often consume less electricity than a similar-sized window AC with a lower star rating. 

• Inverter vs Non-Inverter Technology: Many modern split ACs have inverter technology. This means the compressor can adjust its speed based on the cooling demand. This saves energy, reduces the number of start-stop cycles, and improves the AC's efficiency. A window AC without an inverter system runs in fixed cycles, which can be less efficient.  
   

• Room Size and Usage of AC: If the room is small or the AC is used only frequently, a window AC may be sufficient, and it will not consume a lot of power. However, for larger rooms or frequent use, a split AC system can be more efficient because it can cool the space more evenly and does not have to overwork. 

So, does a window AC consume more electricity than a split AC? Generally, yes, especially over longer periods or in larger rooms, assuming the split AC is of good efficiency.

Price Comparison

Thus, when considering long-term savings, split ACs, if used and maintained regularly, have the upper hand over window ACs. But the purchase cost of a window AC is affordable. 

Which one is better?

Putting everything together, here is a guide to help you decide:

1. Choose a window AC if

• Your room is small (bedroom, or small office).

   

• Your budget is tight (both for purchase and installation).

   

• You need quick installation.

   

• Usage is occasional (few hours a day).

   

• You have a proper space for window AC placement. 

   

• Here is a model you can take a look at- Voltas 1.5 Ton 5 Star Adjustable Inverter Window AC | High Ambient Cooling | SuperDry | Turbo Cooling | Anti Dust Filter

   

1. Choose a split AC if

• Your room is larger (living room, medium-to-large bedroom or open plan), or you want more even cooling.

   

• The noise level matters (split ACs are quieter indoors).

   

• You use the AC for several hours daily.

   

• You want better efficiency (especially with inverter technology) and lower electricity bills (long term).

   

• Here is a split AC model for you to look at- LG 1.5 Ton 5 Star AI DUAL Inverter Split AC | Copper | AI Convertible 6 in 1 | VIRAAT Mode | Faster Cooling | Energy Saving | 4 Way Swing | HD Filter with Anti Virus Protection

   

Conclusion

The comparison of split AC and window AC shows that split ACs can perform slightly better in terms of energy efficiency, cooling, noise, and comfort. But window ACs still hold value in the right places and contexts. There is no one-size-fits-all answer. Split AC vs Window AC: Which one is better? It depends on your room size, use, budget, and preferences. 

• So, if your priorities are lower electricity cost, better cooling, less noise, and you are okay with the higher upfront cost and complex installation, a split AC will make more sense. 

   

• Also, if you have a large room and need the AC daily, go for a split model with a good star rating. 

   

• But if you want affordability and ease, a window AC is still a viable option.
