Now that we have an overview of the differences let us get into the details of each feature to determine which AC is better—window or split.
1. Design: Split AC vs Window AC
The primary difference between window and split AC is the packaging of its components.
Window AC – The compressor, condenser, expansion valve, cooling coil and other parts are inside a compact portable box. You can install the whole casing in one place in the room.
Split AC – The AC has two structures: outdoor and indoor. The compressor, condenser and expansion valve are inside the outdoor unit. On the other hand, you must install the capillary tube (expansion element), evaporator and cooling fan inside the room in the indoor unit.
2. Application: Split AC vs Window AC
Fundamental differences between window AC and split AC make them suitable for specific purposes according to their features.
Window AC – Due to its portable construction, this unit is suitable for transferable applications like people living on rent. Also, this is a better fit if you want an AC for smaller rooms.
Split AC– These AC units are most suitable for large spaces like offices, conference halls and oversized bedrooms. Its sleek design and minimum noise can also be a deciding factor if you want an AC to match the aesthetics of a room.
3. Space: Split AC vs Window AC
Another critical factor in the battle titled “split AC vs window, which is best?” is the space it takes after installation.
Window AC – Since all the parts are inside a single case, it takes up more space inside a room. Also, you have to install it on a window that may block daylight and pose a security threat.
Split AC – According to guidelines, you must maintain a six feet distance between the indoor and outdoor unit. And, since the indoor unit is the only structure inside the room, it takes up less space and can also be mounted on the wall of your room.
4. Capacity Range: Split AC vs Window AC
The capacity indicates the ability of an air conditioner to cool a room of a specific size. It is an essential parameter to decide which is better, window or split. The higher the capacity, the easier it is to cool a large room. Choosing the suitable capacity is also vital to prevent electrical equipment from overheating.
Window AC – It comes in various capacities but is limited to 2 tonnes. This makes it not suitable for large spaces.
Split AC – The capacity can vary according to the size of the room. It has no maximum limit, and you can buy the one that suits your needs.
5. Maintenance: Window vs Split AC
For people looking for budget solutions, maintenance costs can be a deciding factor in the battle of which AC is best—window or split.
Window AC – These ACs have a compact design, so they do not require much maintenance unless any part inside the case is not working correctly.
Split AC – These units require regular servicing with the help of an expert. Also, the servicing cost may be higher since there are two separate units.
6. Noise: Window vs Split AC
This is the most prevalent difference between window AC and split AC.
Window AC – As the compressor is in a single case inside the room and closer to the user, it creates considerable noise as soon as it starts operating. This can be an inconvenience for people in the room.
Split AC – Since the compressor is in the outdoor unit of the AC, its noise does not affect the users inside the room. So, split AC can be a better choice if you are looking for an AC for your workspace or modern home decor.
7. Energy Consumption: Window vs Split AC
Many customers nowadays consider the power consumption and environmental impacts before deciding which AC is better, window or split. You can find this out from the start rating on the AC. The higher the rating, the more efficient your AC is.
Window AC – Many window ACs still use chemicals that have high global warming and potential, like the R22 refrigerants. This makes it an unfavourable option for many consumers.
Split AC – All split AC units use R32 refrigerants, which are pretty efficient in reducing your carbon footprint. They can also extract heat more easily, making it a better choice for decreasing the overall burden on the environment.
8. Buying Costs: Window vs Split AC
Your purchasing power will determine the variant between split AC vs window AC, which is best for you.
Window AC – These ACs can start as low as Rs 15,000 and are generally not that pricey. It is a go-to choice for people looking for an air conditioner on a budget.
Split AC – The starting price of these ACs is around Rs 25,000, irrespective of tonnage. The price also increases as you increase the capacity and look for more features.
What is Window AC?
It is the simplest type of AC unit. It is a single box with all the parts and components contained inside it. Generally, you must mount the AC onto a window, hence the name. To run it, you have to plug it into a traditional electrical outlet.
What is Split AC?
In this, two separate units help in the AC’s functioning. There is an air-cooled condensing unit commonly known as the compressor and an air-handling unit. You must install the compressor outside the room and fix the air-handling unit inside the room.
This significant difference between window AC and split AC gives the latter an edge in the battle for which AC is best—window or split.
The Conclusion: Window AC vs Split AC–Which one is better?
Both variants are adapting newer technologies to win the race of which AC is best, window or split. But as a consumer, you must choose an air conditioner that meets your physical and financial needs. For example, buying a three-ton split AC for a 1BHK can be an unnecessary investment.
So, go through the information above to understand the difference between window AC and split AC. Look for the features that are absolutely essential for you. The variant that has what you need is the winner. And Get Tata Capital Consumer Durable Loan To Buy AC you decide on!
Why does a window AC consume more electricity than a split AC?
Window ACs consume more electricity than split ACs because they have all their components in one unit, which reduces their ability to facilitate effective cooling. Split ACs have separate indoor and outdoor units, facilitating improved energy efficiency and temperature control. Further, split ACs also offer advanced technology and higher energy-saving features than window ACs.
Which is more energy-efficient, a window AC or a split AC?
Split ACs are more energy-efficient than window ACs as they feature better energy ratings and advanced technology such as inverter compressors, leading to better electricity consumption. Further, their quieter operation and better cooling efficiency also make them a better choice.
What factors should I consider before deciding between a window AC and a split AC?
When choosing between a window AC and a split AC, consider factors such as installation complexity, budget, room size, and noise levels. While split ACs are better suited to large rooms and offer quieter operation, their installation and upfront costs can be higher than those of window ACs.
What is the lifespan of a window air conditioner?
A window AC’s lifespan is between 8-10 years with regular cleaning and timely servicing.
How many hours should a window AC operate daily?
A window AC should operate for 6-8 hours daily, depending on the temperature, room insulation, and required comfort level.
What are the disadvantages of a window AC?
Window ACs are often noisy and take up your window space. They don’t look as neat, cool slower in larger rooms, and usually consume more electricity compared to split ACs. Their cooling and design may not suit modern homes.
Can I install a split AC by myself, or do I need professional help?
Installing a split AC isn’t easy and needs drilling, wiring, and proper pipe connection. It’s best to call a trained technician. A wrong setup can damage the unit, affect cooling, and even lead to safety issues during use.
How many hours should a window AC operate daily?
A window AC can run for 6 to 8 hours daily depending on the weather and room size. Running it longer increases power use and can lead to faster wear and tear, so use it based on your need.
Do Split ACs offer better temperature control than Window ACs?
Split ACs generally offer better temperature control, faster cooling, and quieter operation. They often come with advanced settings and smart features, making them more efficient and comfortable to use, especially in bigger rooms or for longer hours.
