Buyer’s Guide – an Intensive Guide to Get the Best Windows ACs in India for Your Needs

How Does A Window AC Works?

As the name suggests, a window AC fits in the space created when you open a window. Most window ACs are engineered for single-hung or double-hung windows. However, the major companies now make window ACs for sliding and casement windows.

Certain homeowners frame a permanent sleeve through a wall to accommodate the window AC. Upon installation in the wall, the window AC won’t obstruct a window. This kind of installation is also known as a built-in unit.

A window AC utilizes refrigerant to absorb heat inside your home and disperse it outside. This is the reason why the back of the air conditioner seems like a radiator. Its optimum surface space enables faster dissipation of the heat.

Inside air is pulled over a coil in the front of the AC. The heat from the air is captured by the refrigerant in the window AC’s coil. Taking heat from the air will eventually make it cooler, and the cooled air is then blown into the room.

Advantages and Disadvantages of Window AC

Exploring window AC’s pros and cons is another way to compare your home cooling choices:


Lower replacement cost – when your central air conditioner or ducts must be replaced, and you don’t have enough money for the replacement, windows ACs are actually a good short-term problem-solver.

Lower total cost in first 5-20 years – if home size lets you cool the entire home with one large or 2 smaller air conditioners, your total cost for the machine, installation process, and energy will be lower in the first five years in hot climates, and first ten to twenty years in colder climates.

Installation cost – installation of a window air conditioner is DIY for most units. On the other hand, installing a central system costs 103,900 Rs. to 346,000 Rs. It depends on its configuration and size.

Unit cost – windows AC have a much lower upfront cost of around 14,000 Rs to 28,000 Rs. For small, basic window ACs, obviously, it could be a lot higher. And much higher unit cost if the AC is a full-featured window AC.

Power outages – when the power suddenly goes out, a window AC can be run off a small generator. It takes a whole-house generator to power a central AC during an outage. In short, window ACs are much more convenient in terms of this sudden occurrence.

Much quieter compared to their previous versions – though still not as quiet as central AC since the unit is inside, lowering the decibels of window ACs has been a major emphasis, and they’re quieter than ever.

No waster AC – when the members of your house are occupying just a few rooms, cooling the entire house can be a waste of money compared with cooling certain rooms. For instance, one large air conditioner might cool the living area and kitchen during the day. Then, one or two small window air conditioners can cool the bedrooms during the night.

Cost effective for small homeowners – window units comes with a more reasonable price ranges workshops, offices, apartments, small homes, and similar space where they can provide sufficient cooling.


Support might be needed – very large window ACs need one or at least two brackets in order to support their weight, and the unit falling is a great risk.

Hassle to move – moving a window AC from room to room is a daunting task.

Potential security risk – the unit must be installed to preclude intruders from accessing your home through the partially opened window.

Water damage potential – water draining from a window unit might rot or stain the home’s siding. Wind-driven rain might also get into your house around the sides of the window AC and might cause interior damage.

Blocked window – when an air conditioner is placed in the window, the view will be obviously obscured.

Limited cooling in hot climates – unless you have a very small home, houses in hot climates need 3-5 window ACs to do the job of central air conditioning units.

How to Purchase A Window AC Based on Your Needs

Here are the tips when buying a window AC:


An ideal principle is to pay for features you’ll need use, but don’t waste your hard-earned money on those you won’t really use. Wi-Fi feature is an appropriate example. It’s a nice way to reduce AC usage and still have your home comfortable when you’re there. Nonetheless, if you’ve got a very hectic schedule, then a timer would suffice. If the unit is placed in a room that you only use at a certain time of the day, then you might not need any specialized and certain features. In fact, a very basic and regular AC would be good enough.


If the window AC is the main source of cooling, then the general rule of thumb is that warmer climate = higher efficiency air conditioner. If it’s only supplemental air conditioning for rooms and not fully cooled by central air conditioning, then you can opt for a less efficient unit.


A good rule of thumb is that the hotter and longer your summers are, the more money you’ll be able to save with a more efficient air conditioning.


Determine the capacity of the air conditioner you must have. By doing this, you can limit your shopping to window ACs that will run comfortably and efficiently in your house.

Features to Consider When Purchasing the Best Window ACs in India

Window air conditioners range from very basic on and off units with a fan speed knobs to feature-packed air window air conditioners. Obviously, the better the features, the higher the average cost of the window AC will be. Here are some of the options to consider when you’re shopping:

Wi-Fi – window ACs with this feature let you control them remotely using an app. It’s the easiest way to minimize energy use. If you forget to turn the unit off when you leave home, you can do the work using the app.

Timer and programmable start – these particular features let you plan when the AC turns on and off and for how long it will run. Using these features let you cycle the AC on and off in moderately warm weather in order to save energy. Additionally, using programmable features is the best way to minimize energy use when you’re not at the house. Instead of leaving the unit on all day long, you can program it to turn on 30-60 minutes before you arrive.

Digital controls – most ACs have digital controls. However, the most affordable air conditioners come with knobs. Digital control lets you set the temperature more accurately. It’s also necessary for sleep mode, timer, and other features.

Fan speeds and fan-only mode – window units have 2-4 fan speeds. And there are those that have the fan-only mode. Climate control within the space or room is much easier with more fan speeds. Pick a low speed if you’re sitting near the air conditioner and higher speed when you want cool air to reach the far side of the room. Fan-only mode lets the air conditioner to continue to dehumidify and filter the air even when the compressor is not running.

Inverter or standard compressor – standard compressors operate on one or two speeds. Inverter-type compressors speed up and slow-down in every small increment. They run longer during each cycle, but they cool the space more gently and evenly without any blasts of chilled air. The outcome is that an AC that comes with an inverter compressor uses less energy and cools more effectively. Nonetheless, it can cost more than a same-size air conditioner with a standard compressor.

Auto restart after sudden outage – with this feature, the AC will turn on and return to your settings when power is restored. If you aren’t at home during the outage, you can return home to a less humid, cooler house.

Ionizer – this feature is an air cleaner that captures pollutants through an electronic charge. A window AC with this kind of feature can produce much cleaner air.

Tips to Reduce Energy Cost of Window AC

Purchasing an effective window AC is just the first step. Here are the ways to minimize the energy use of your unit:

Consider a whole-house fan – the fan is engineered to exchange the warm air in your home for cooler night-time air. These particular fans cost far less compared to central AC. When the house is cooled off at night, it will stay cooler longer when daytime, so less AC will be needed.

Use kitchen vent and bathroom vent fans when cooking – removing moisture from the air makes the air feel more relaxing during warm months.

Add insulation to the attic – energy experts use this method to cut down on energy expenses and make your home much more comfortable. Enough attic insulation is the best way to stop summer heat from penetrating through your room, making your home hot, and your window AC to work harder. It keeps in heat during the winter season too.

Use a ceiling fan or floor fan to move air – moving air feels cooler compared to stagnant air.

Add weather stripping around the AC. Stop drafts from letting cool air to escape and warm air to enter the room.

Install an awning above your AC window. This is a permanent and much more effective way to shade a sunny window.

Shade sunny windows – thermal shades are available in order to minimize the transfer of heat into the room. Less heat means the AC doesn’t work at work.

Use the timer to program on and off times instead of leaving the window AC on when you’re not even in the room.


And now let’s end this discussion by announcing the winner of this roundup. Well, without further ado, the Voltas 1.5 Ton 5 Star Window AC (Copper,185 DZA/185 DZA R32) wins the round.

This particular window air conditioner is a high-powered unit that comes with an ideal weight to install and is an efficient window AC that can be fitted pretty much anywhere. In addition, it is also equipped with a high-powered rotary compressor which gives more power when it is operating.
