Buyer’s Guide: What to Look for When Buying A Window AC in India?

We need cool conditions indoors inside our homes and at the office to be at our most productive. We humans feel comfortable in temperatures of 20 to 30 degrees Centigrade and hot summer temperatures of 40 degrees Centigrade and higher are uncomfortable, will likely make us less productive and can be unhealthy as well.

If you have decided to purchase a window AC, the decisions to make are regarding size, features, price and energy rating.

Air Conditioner Sizes — 1.0 ton Vs. 1.5 ton — And Room Sizes

You could buy a 0.5 ton or 1.0 ton or a 1.5 ton AC. What does this ‘tonnage’ of an AC indicate? It just indicates the amount of air an AC can cool.

For those mathematically inclined, 1 ton equals 12,000 BTU/hour cooling capacity where 1BTU is the amount of heat needed to raise the temperature of 1 pound of water by 1 degree Fahrenheit and 3,412 BTU = 1KW/hr.

What is important is to be able to find the right capacity AC for your room which depends on the size of your room, the city where you live, the maximum temperature during summer in your city and also the number of people typically using that room.

As a rule of thumb, small rooms up to 80 square feet in size can be cooled by a 0.75 ton AC while 80 to 120 square feet size rooms will require a 1 ton AC, 120 to 180 square feet size rooms are best fit for 1.5 ton ACs and finally, rooms bigger than that will ideally require two 1 ton or 1.5 ton ACs.

Features

All sorts of things – from household appliances to automobiles – have improved in quality thanks to competition and ACs are no exception. So, while the typical window AC will come with copper coils and a five year warranty on its compressor, some of them will offer additional features – if you can absorb the slightly higher cost of those features such as Turbo cooling capacity, a sleep mode, air filters, or a dehumidifier, it’s better to opt for an AC with these features without worrying about manufacturing or quality issues.

Price

Since this is a purchase decision which you will be making quite rarely – about once a decade or even less than that – it’s better to take a holistic decision keeping the price of the AC as only one of the factors while taking your decision.

While window ACs may be priced anywhere from 20,000 rupees to 35,000 rupees, all the ACs on our list will do their job well. The premium price products will offer a few additional features such as internal stabilizers or dehumidifiers.

It’s up to you to decide how important those additional features in your window AC are to you considering your locality’s climate and other factors.

Energy Rating/Power Consumption

Expect your AC to consume 1,000 units or more of electricity per year. A typical 1.5 ton window AC needs and draws about 1,500 watts. If you operate your AC for six to seven hours every day during summer, you can calculate the energy consumption this will entail: 9 units per day or 270 units per month during the hot months.

This makes the energy star rating of a window AC something important to keep in mind as a 5-star rated AC will consume less electricity than a 3-star rated AC and save you thousands of rupees in electricity bills over the lifetime of the AC.

Considering how electricity prices have grown, no wonder all sorts of electrical appliances – AcC, refrigerators, washing machines – come with Bureau of Energy Efficiency (BEE) energy ratings these days.

Naturally, most of the ACs we have reviewed in this compilation of the best window ACs – including the Voltas and Hitachi models at the top of this list – are 5-star rated.

Purchasing Window Air Conditioners Online

Less than 10 percent of Indian households have air conditioners. So, most of those purchasing ACs are likely to be first time buyers. With Amazon around, there is the added option of buying ACs online apart from the traditional option of buying from ‘showrooms.’

There is no problem with buying products such as air conditioners online these day as long as you are buying from reputed online websites such as Amazon and installation and after sales service will also be smooth when you buy from reputed air conditioner companies such as Voltas, Hitachi, LG, Career, Whirlpool and Blue Star, etc.


Frequently Asked Questions (FAQs)

An air conditioner is a device that puts the air in an enclosed area through a refrigeration cycle and either makes warm air cooler or cool air warmer. In the tropical climate of India, for the purposes of this buyer’s guide that compares and determines the best window ACs in India, we are only concerned about the ability of a window AC to cool things down.

What is a Window AC?

An AC comprises these three main components: compressor, refrigerant and condenser coil. In a window AC, all these components are inside one compact unit which is mounted on a window so that the heat is removed from inside the room and radiated outside.

While the technical details of the compression -> condensation -> expansion cycle performed by the components named above are quite, well, technical, the end result is that the cycle is repeated till the desired room temperature set by you is reached and then the compressor shuts down.

When the temperature rises after a while, the AC detects this ‘anomaly’ and the compressor kicks in and the cycle starts again to bring the room temperature back to ‘normal.’

What Is The Difference Between Window AC And Split AC?

Since you are out buying an AC, it’s best to be familiar with the two basic types: window and split ACs. So, what is the main difference between them?

Window AC

A window AC comes as a single unit and as its name suggests, it needs to be fitted on a window of a room. Hence, window ACs go in a room which has at least one side with a window. These are convenient to install especially in apartments. Since there are no tubes going from one unit to another, that means less of a hassle to install and maintain and there is less chance of trouble with the machine which in turn means less dependence on the ‘after sales network’ or the neighborhood ‘AC mechanic’ or the local electrician who has mastery over all things electrical.

Split AC

Split ACs come in two parts: an indoor part and an outdoor part. The indoor part goes on a wall inside a room while the outdoor part is kept outside – possibly on the terrace. This is appropriate if you live in an independent house and are doing long term planning. The installation process will be labor-intensive and you’ll incur more expenses for sure – in both labor costs and material costs.

With two ‘units’ to this AC, split ACs are naturally more expensive of the two.

Does A Window AC Have To Be In The Window?

No. A window AC need not go inside a window. However, it needs a rectangular opening. So, a rectangular cut in a wall will work fine. Just make sure the AC unit is snugly fit inside the opening. The installation kit will come with material such as side curtains which are to be used to seal off any additional space left in the window or the wall opening.

What Size Window Air Conditioner Do I Need?

There are no fixed rules regarding this – only common sense rules of thumb which will need to be supplemented by your personal inclinations and intuitions.

The basic ‘rule’ is that a 1.0 ton window AC is adequate for a 120 square feet size rooms, 120 to 180 square feet size rooms are best fit for 1.5 ton ACs and finally, rooms bigger than that will ideally require two 1.0 ton or 1.5 ton ACs or a 2.0 ton AC.

You also have to take into consideration how many people (or pets) will be normally residing inside or using the room, how much of direct sunlight the room gets and so forth.

Will Energy Star Rated Models Save Money?

Of course, window ACs with 5-star rating will consume less electricity than those rated 3 stars or 2 stars. Our reviews include mostly 5-star rated ACs which will save energy and save you money as well.

You can take a look at the BEE rating of a given AC or brose the details spec sheets for a given brand or manufacturer such as this one. You can see the difference in the ‘Rated Power Input’ row – a 1.0 ton model requires roughly 1KW/Hr while a 1.5 ton model requires 1.5KW/Hr and a 2.0 ton model has the maximum electrical power consumption at about 2KW/Hr.

You can calculate how much you will be spending extra on electricity bills by checking the power requirements for various models that have different energy star ratings.


Conclusion

In summary, with summers getting ever more scorching, air conditioners have become must-have appliances in Indian households. When it comes to typical homes, window ACs are the best option if you are on a budget. (Of course, sometimes you may want to — or need to — get away from nice, comfy air-conditioned rooms, go off beaten tracks and take on the worst that the Rajasthan summer has to offer.)

We have surveyed the 10 best window ACs in India for 2020 and the winner in our view is the Voltas 1.5 Ton 5 Star Window AC.
