Split ACs Vs Window ACs: Which AC Should You Buy?

With rising temperatures, having an air conditioner becomes important. But which one should you buy: a Split AC or a Window AC? If you are confused between the two, we’ll explore the differences between Split ACs vs window ACs. In this guide, we’ll talk about the benefits and drawbacks of both types of AC to help you make the best decision for your home and lifestyle. Let’s find out which AC suits your home best.

What are Split ACs?

Split ACs are a popular cooling solution that consists of two main units, an indoor unit and an outdoor unit, which are connected by refrigerant pipes and electrical cables. While the indoor unit cools the air, the outdoor unit dissipates heat. Such ACs are known for their quiet operation, sleek design, flexible installation, and energy efficiency.

What are Window ACs?

Window ACs are self-contained units that fit into a window or a specially prepared wall slot. They combine all components, such as the compressor, condenser, evaporator, and fan, in one box, which makes them easy to install and remove without professional guidance. They are also cost-effective, compact, and offer effective cooling in small spaces.

Window ACs

Window AC Installation

Window ACs are easy to install and fit into a window frame or wall slot. You can place the unit, seal any gaps, and secure it—usually without needing professional help. This quick, convenient installation process makes such ACs ideal for renters. These units are more affordable initially, with lower purchase costs and no professional installation fees. However, they generally have lower energy efficiency, which can lead to higher electricity bills over time.

Cooling Efficiency and Performance

Split ACs

These ACs are well-known for their high cooling efficiency and superior performance.  The separate indoor and outdoor units allow for optimal airflow and cooling, making them a perfect choice for larger rooms and multi-room setups. Also, they often feature advanced technologies, such as inverter compressors, which adjust the cooling output according to room conditions while ensuring consistent temperature control and saving energy. Moreover, Split ACs like Haier 1.5 Ton 3 Star Smart Split AC operate quietly, offering the utmost comfort in bedrooms and workspaces.

Window ACs

Window ACs are effective cooling solutions for smaller spaces, with all components combined in a single unit. Because of their compact design, they are generally less efficient than Split ACs but are capable of cooling moderately sized rooms effectively. However, they tend to be noisier since the compressor and fan are housed together and are not usually preferred to be installed in rooms where silence is needed. 

Energy Efficiency

Split ACs

They are typically more energy-efficient, especially models with inverter technology like Samsung 2 Ton 3 Star Inverter Split AC, which adjusts their speed based on cooling demand, reducing energy consumption and lowering electricity bills over time. Also, split ACs often come with higher Energy Efficiency Ratios (EER) and Seasonal Energy Efficiency Ratios (SEER), making them a more sustainable choice for long-term use. Their ability to maintain a consistent temperature without frequent on-off cycling further boosts energy efficiency.

Window ACs

They generally have lower energy efficiency compared to Split ACs.They often lack advanced inverter technology, which results in higher energy consumption, especially during continuous use. While many of them, such as Voltas 1.5 Ton 3 Star Fixed Speed Window AC, come with energy-saving features, such as sleep modes and programmable timers, their overall Energy Efficiency Ratio (EER) tends to be lower. This makes them less suitable for extensive, long-term use for people who prioritise minimising electricity costs.

Maintenance and Durability

Split ACs

Split ACs require regular maintenance to maintain peak performance. This includes cleaning or replacing filters, checking refrigerant levels, and servicing both indoor and outdoor units. While this maintenance can be more comprehensive and often requires professional services, such ACs are typically more durable and have a longer lifespan. Their components are designed to handle continuous, heavy-duty use and are a reliable choice for long-term investment.

Window ACs

Window ACs are relatively easy to maintain thanks to their single-unit design. Their regular maintenance includes cleaning filters and ensuring the unit is free from obstructions. While simpler to maintain, such ACs are not as durable as Split ACs, particularly in harsh environments with high dust or pollution. Their all-in-one construction can lead to quicker wear and tear, potentially shortening their lifespan compared to the more robust Split AC systems.

Aesthetic and Space Considerations

Split ACs

These ACs are designed to be sleek and modern and can blend seamlessly with interior decor. The indoor unit is typically mounted high on a wall, freeing up floor and window space, and does not obstruct natural light or views. Additionally, their flexibility in placement allows for better room design and layout, enhancing their functionality and making them perfect for preserving a room’s aesthetic appeal.

Window ACs

These ACs are bulkier and can detract from a room’s overall aesthetics. Since they are installed in a window frame, they block natural light and views, which can be a significant drawback in spaces where window access and natural lighting are important. Although they are practical and conserve space for single-room cooling, window ACs need to have the sleek, unobtrusive appearance of split ACs,  making them less desirable from a design and aesthetic standpoint.

Technological Features

Split ACs

Split ACs are equipped with cutting-edge technology, such as inverter technology, for energy efficiency and consistent temperature control. Many models like Panasonic 1 Ton 5 Star Inverter Smart Split AC include Wi-Fi connectivity for remote operation, air purification systems, multi-stage filtration, and smart diagnostics that boost performance and convenience. Moreover, some split ACs are compatible with voice commands and can integrate seamlessly with home automation systems. While you get access to advanced technologies, they come at an extra cost. 

Window ACs

Window ACs, though typically less complex, offer useful features such as programmable timers, sleep modes, and energy-saving settings. Many models come with remote controls and digital displays that enhance efficiency and user experience. Some advanced units include basic air purification and smart functionality like Wi-Fi connectivity for smartphone control. For instance, Lloyd 1.5 Ton 3 Star Fixed Speed Window AC features a self-diagnosis function, offers strong dehumidification, and comes with a digital dynamic LED display for enhanced functionality.
