How to Choose a 1.5 ton Window AC in India?

Before you invest in a 1.5 ton window ac for your home or office, make sure to check out the important factors that will help you in making the right decision.

Here are some essentials that will help you go about finding the right air conditioner.

Room size considerations

This is one of the most important factors to consider when buying a window air conditioner.

The capacity of the AC is determined in tons. Both the types of air conditioners, split and window are available in different capacities.

Remember that the tonnage of the appliance does not mean its weight but it is the rate at which the air conditioner can cool the space. Thus, a larger space requires an AC with higher tonnage.

The below-mentioned table will help you know the right tonnage depending on the size of the room and budget.

Room SizeTonnage
100 -125 sq. ft.1 ton
150 – 200 sq. ft.1.5 ton
200 and above sq. ft.2 ton

Remember that sunlight may increase the thermal units by 10% and so does higher ceilings of more than 8 feet.

Yes, the size of the room is important to decide the tonnage but there are some other factors that you need to consider too.

For instance, the size of the windows is important to know because the bigger the window, the more cooled air can pass through it and thus the room can’t stay cool for a long time.

You also need to consider the amount of sunlight entering the room because that can increase the temperature of the room, especially in summer.

In the same way, the number of lights in the room is an essential factor to consider because it generates heat. Similarly, more number of electronic appliances running can shoot up the room temperature.


Make sure to measure the dimension of the inside of the window where you wish to install the ac. Pay more attention to the width and get exact measurements.

After you have found the dimensions, check the minimum and maximum width dimensions mentioned in the window AC’s requirements.

It is not a problem if the ac does not fit the window frame exactly but ensure that the window is bigger than the ac.

All window air conditioners come with an installation kit that includes necessary items like side curtains to seal the additional space.

Electric requirements

The window acs are more powerful compared to other regular household appliances that we use. Ensure that your current electrical system can bear the load.

Most air conditioners available in the market today operate on 115 – 125 volts or 220 vol circuits.

115 – 125 volts

Air conditioners with a cooling capacity below 15,000 BTUs run on the standard voltage of 115 – 125 volt circuits.

220 volts

Air conditioners with a cooling capacity above 15,000 BTUs run on the 220 volt circuit. This may require you to install special writing, thus ensure to call a professional for installation.

You will find all the electrical requirements like voltage, watts, and amps in the air conditioner’s specifications.


To ensure the window air conditioners are in their best condition, they need to be maintained periodically.

They are vulnerable to dirt and debris that accumulates inside. Dust will also build upon the ac’s air filters with time. If this is not cleaned regularly, it can affect its effectiveness of cooling.

Thus, ensure to clean the air conditioner once every six months. If your window ac has slide-out chassis then it is convenient to clean because you need to just slide it to access.

Also, most acs come with air filters that are washable with mild soapy water. Make sure to read the manual before cleaning the air conditioner.

Energy efficiency

When compared to other types of air conditioners, window acs are economical. They are priced affordably and when you pick the right one, it is cheaper to operate as well.

To understand the air conditioner’s energy efficiency, consider the below mentioned two features.

Energy Efficiency Ratio (EER)

This tells you how many BTUs the ac uses for every watt of power. You need to use this measurement as a rule of thumb. The higher the energy efficiency ratio, the more efficient is the ac.

It is good to look for an ac that has a minimum of 10.0 EER.

Energy Star Rated

An ac with an energy star rating uses approximately 10% less energy when compared to other models. This helps you save money on energy bills.


The price for 1.5 ton window air conditioner ranges from Rs. 24,000 to Rs. 37, 000 based on the brand, energy efficiency, smart features, etc. Make sure to understand your needs and then make an investment.

Does window AC consume more electricity?

It depends because the window air conditioner is moderately energy efficient. Actually, w window ac is as energy efficient as a split air conditioner.

The main difference is all about the Energy Efficiency Ratio of the ac. The Bureau of Energy Efficiency rates the acs in the range from 1 to 5 stars depending on how energy efficient it is.

Window air conditioners get high and low ratings by the BEE depending on the model. The voltage of the appliance is important too. In case the voltage is the same for two acs then the EER will decide which one is more energy efficient.


Air conditioners are an essential appliance in some parts of the country, especially during the summer. Make sure to check out the essential factors before you make an investment.
