Buying Guide For 1 Ton ACs – Important Points That Merit Consideration

Nowadays, not many people purchase window ACs as inverter split ACs are available in plenty. One of the prime advantages of a split air conditioner over the window-mounted unit is that the former saves considerable energy over its lifespan. Therefore, the split air conditioners might be initially expensive, but they are economical in the long run.

Let us go through some tips to help you finalize your 1-ton AC.


As you have already decided on the tonnage, we do not discuss this aspect much in detail.

However, the uninitiated will benefit from this discussion as we define the term and explain it in brief. Tonnage is nothing but the cooling capacity of the system.

One ton signifies the amount of heat required to melt one ton of ice in 24 hours.

Therefore, the ability to remove this amount of heat in 24 hours represents the tonnage capacity of the air conditioner.

The ideal tonnage for your AC depends on various factors.

The area and volume of the room is a crucial aspect. Generally, rooms with less than 13 square feet area or around 1300 to 1400 cubic feet volume require a 1-ton AC. If your room has a higher figure, it is advisable to go for higher tonnage.

You should also check out whether the walls and windows of the room face the sun, especially the west direction. Accordingly, it affects the tonnage. Similarly, if there is no floor above your room, the ceiling is exposed to the sun directly. It affects your appliance’s cooling performance.

The number of family members in the room has a direct bearing on the AC capacity. If your room has a lot of furniture, you might need an air conditioner with a higher power. Similarly, multiple electrical devices in the room affect the device’s capacity.

Generally, the bedrooms in Indian apartments today have an area of around 130 square feet. A 1-ton AC should suffice.


Energy efficiency is a critical aspect of any electrical/electronic appliance. The electricity costs are rising in almost every Indian city. Therefore, it is advisable to opt for devices that save you the maximum power. At the same time, the performance should be of the highest quality.

The Bureau of Energy Efficiency makes it simple for you by standardizing the energy efficiency factor of ACs. Every manufacturer must display the BEE star rating prominently on the device.

The thumb rule says that the higher the rating, the more efficient is the machine. By this yardstick, a 5-star rating is better than a 3-star.

The 5-star rated appliances are initially more expensive than the 3-star rated devices. However, you end up saving more power over the machine’s lifespan. Thus, you end up with a better deal overall.


Nowadays, window ACs have become rare. People prefer to go for split ACs. These appliances feature two types of compressors, the conventional one and the inverter compressor.

The difference is that the inverter compressor works at varying speeds, depending on your cooling requirements.

The conventional compressor works at a single pace. Hence, they switch off on attaining the set temperature. They switch on again when the temperature falls below the minimum threshold. Therefore, the conventional compressors consume more energy.

The inverter compressors are more energy-efficient than conventional motors. Today, you have ACs with dual inverter compressors. You also get rotary and reciprocator compressors, whereby you have a wide range to choose from.

Performing Modes

The advanced technology available in the AC manufacturing industry enables these appliances to perform in different modes. However, each manufacture uses a specific term to indicate particular modes.

The Default mode is common to all devices. The Cool mode provides instant cooling and relief during hot summer days. It works by increasing the fan speed by around 30% to 35%. However, this mode consumes more power.

The Sleep Mode is also common in almost all 1-ton appliances. This mode allows you to set a timer to control the AC operation. It provides relief during the nights as you do not have to wake up to switch the air conditioner on or off.

Some models feature a unique facility where the temperature increases by 1-degree Celsius every hour for two hours. Subsequently, it maintains the temperature throughout the night.

Some of the models feature a Dry Mode that proves helpful in the monsoon season. This mode uses a dehumidifier to dry out the moisture and thereby provide comfort to the user.

Air Purifier

Air conditioners function by eliminating the heat from inside the room and circulating cool air. As the same air keeps circulating in the room, it can get polluted. The modern-day appliances feature air purifiers that remove pollutants and improves the quality of the air inside the rooms.

Some models feature different types of filters like Catechin filter and PM 2.5 filter to eliminate bacteria and minute dust particles like pollen, animal dander, etc.

Such machines are handy when you have older adults with asthmatic issues and children in the home. They get pure and fresh air to breathe. Some of the latest appliances feature mosquito repellants. If you reside in a mosquito-infested place, this feature can prove handy.

Protection Features

Your AC works as the refrigerant flows through the condenser and evaporator coils.

Therefore, it is essential to maintain the condition of these coils to ensure the appliance’s longevity. Air conditioners come equipped with either copper or aluminum pipes. These metals are the best when it comes to resisting corrosion.

As an added protection feature, manufacturers paint these coils with anti-corrosion ingredients. Hence, you have Blue Fin and Golden Fin technology that protect these pipes from corrosion.

Individual manufacturers give different names like Shield Blu, Golden Fin, Blue Fin, etc. This protection is essential, especially if you live in coastal areas where there are salt and humidity in the air.

Air conditioners today come equipped with protective capacitors that provide fire safety to the machine in the event of disconnection or a short circuit.


The common refrigerant found in almost all ACs today is R32 refrigerant. It is an eco-friendly coolant with zero ozone depletion potential. Besides R32 consumes less volume. Hence, it is more efficient than some of the other coolants available on the market.

Let us understand the refrigerant’s role that forms the bedrock of the AC’s functioning.

At the outset, the refrigerant is a gas. The compressor compresses the gas at high pressure and converts it into a high-pressure liquid. Due to extreme compression, the liquid becomes hot.

This liquid passes through the condenser pipes to become cool. The expansion valve converts the cool liquid at high pressure to liquid at low pressure. This liquid now flows through the evaporator coils and absorbs the heat from the room to make it cool. The fans play a crucial role in maintaining the temperature.

The absorbed heat converts the cool liquid into a gas again. The process repeats continuously.

Hence, the pipes mustn’t have any leakages. Over continuous usage, the refrigerant gets depleted. You should refill the gas and thus keep the AC working. Some of the latest models feature sensors that detect low gas levels and indicate accordingly.

Stabilizer Functions

In the past, you needed connecting the ACs through a voltage stabilizer, also known as Step-up/Step-down stabilizer or Booster, to take care of voltage fluctuations.

Today, the latest models can work on an extensive input voltage range from 140V to 290V. Therefore, you do not have to invest in a separate stabilizer. You should check out this feature before you finalize the deal.

Auto Restart Features

The Auto-Restart feature is a useful function. On the restoration of power supply, it enables the appliance to restart from where it left off at the time of a power cut. Thus, you do not have to wake up at odd hours in the night to reset the temperature.

Auto Cleaning Features

The Auto Cleaning feature ensures to clean the condenser and evaporator pipes after every use. The AC keeps running for a few minutes after you shut it off. It enables the machine to clean the pipes and thereby, ensure fresh and pure air the next time you switch on the unit.


Almost all AC manufacturers offer a warranty on the machines. The technician cleans the device free of charge. You can opt for an AMC (Annual Maintenance Contract) after the warranty expires.

Simple Tips to take care of your AC

An air conditioner is a good investment. Taking proper care of the appliance can help it serve you longer.

Choose your AC with the right capacity. A smaller AC will not cool your room adequately. A larger AC can consume more power and make it uncomfortable with excessive cooling.

As far as possible, go for a 5-star rated appliance.

Use the appliance only when it is necessary. If there is no one in the room, you can better switch it off.

Use your AC at temperatures in the range of 22 to 24 degrees Celsius. Anything lower than 20 degrees can be uncomfortably cold and will consume more power, as well.

You can run the fan at low to medium speeds when using an AC. It helps in circulating the air better. Otherwise, the hot air in the room tends to move towards the ceiling. If you run the fan after switching off the AC, you could experience a blast of hot air.

Clean the filters at regular intervals. It does not require any technical qualifications to do so.

Service your AC regularly by calling the authorized mechanic. It is better to enter into an annual maintenance contract with a reputed service center.

Check the refrigerant levels and pressure. If there is any depletion, you should refill immediately.
