Each system has its own set of advantages and disadvantages to consider. This article gets into their differences to help you select the AC best suited to your needs and budget.

However, over the last few years in India, Split ACs have overtaken Window ACs because of their features and ease of maintenance over Window ACs.

What is a Split AC?

A split AC system, as the name suggests, consists of two units:

  • Indoor Unit: This sleek unit is mounted high on the wall of the room you wish to cool. It houses the evaporator coil, blower, and air filters.
  • Outdoor Unit: This unit is installed outside the room. It contains the compressor, condenser coil, and expansion valve.

The two units are connected by copper tubing and electrical wires for refrigerant flow and power.

What is a Window AC?

A window AC is a self-contained unit designed to fit snugly into a window opening. All the components – compressor, condenser, evaporator, blower – are housed inside a single box.

Split AC vs. Window AC: Understanding the Pros and Cons

When it comes to cooling your home in India’s diverse and often intense climate, choosing the right air conditioner is crucial. Among the options available, Split ACs and Window ACs are the most popular choices for Indian households.

Each has its unique set of advantages and disadvantages, influenced by factors such as installation, cost, efficiency, and aesthetics.

Split AC: Sleek Design and Quiet Operation


  • Design and Aesthetics: Split ACs boast a sleek, modern design that blends seamlessly with interior décor.
  • Quiet Operation: The compressor and fan for the outdoor unit of a Split AC are located outside of the room, making it significantly quieter than its Window counterpart.
  • Flexible Installation: Without the need for a window, Split ACs can be installed in any room, providing greater flexibility in terms of placement.
  • Energy Efficiency: Many Split AC models come equipped with inverter technology, which can lead to substantial savings on electricity bills, especially when considering AC star ratings.


  • Higher Initial Cost: Split ACs are generally more expensive to purchase and install compared to Window ACs.
  • Installation Complexity: They require professional installation that can be invasive and time-consuming.

Window AC: Compact and Cost-Effective


  • Cost-Effective: Window ACs are more affordable both in terms of the unit cost and installation.
  • Easy Installation: These units are relatively easier to install and can be a DIY project for those who are handy.
  • All-in-One Unit: Because all components are housed in one compact box, Window ACs are straightforward and quick to install and maintain.


  • Noise Level: Window ACs can be louder than Split ACs because the compressor and fan are located within the same unit.
  • Blocks Window Space: Installation of a Window AC can obstruct outdoor views and limit natural light.
  • Aesthetics: They might not blend as seamlessly with room décor as Split ACs do.

Additional Factors to Consider

  • Features: Split ACs often offer advanced features like air purification, Wi-Fi connectivity, various operating modes, and smart controls.
  • Climate: If you live in an area of extreme heat and humidity, a split AC is usually a better option for consistent cooling.
  • AC Star Ratings: Can They Save Electricity Costs?: Discover how selecting an AC with a higher star rating can lead to significant savings on your energy bills.

The Verdict

The best choice between a split AC and window AC ultimately depends on your space, budget, noise tolerance, aesthetic preferences, and desired features.

  • Choose a split AC if: You want quiet, efficient cooling for a larger space, have the budget, and value advanced features.

    Our recommendation is go towards split ACs – the difference in cost isn’t that much and they offer the convenience of a variety of features over Window ACs
  • Choose a window AC if: You need a budget-friendly solution for a small room, want easy installation, or prioritize portability over advanced features.

    We would recommend this for rented homes where the owners don’t allow damage to walls. Or you could use this as a secondary AC for a guest room
