We all are very familiar with the Indian summer. And the heat is increasing every year for the effect of Global Warming. Therefore, air conditioners have become an essential electrical appliance for almost every home in India. When it is about to choose the best air conditioner for your home or office you are confused between an inverter AC vs non-inverter AC.
In this article, we have made a humble effort to help you out finding the difference between inverter and non-inverter ac. We request you to read until the end to get proper knowledge on both technologies and make an informed choice.
So, if you are ready to beat the heat of the summer, continue reading…
Before finding the difference, first, we have to know what is an Inverter AC and a Non-Inverter AC.
What is an Inverter AC?
Presently the demand of Inverter AC unit is on top. If you are thinking of purchasing the latest and the most efficient technology air conditioners, then you surely can go for the Inverter ACs.
An Inverter AC unit comes with a variable speed compressor motor. This motor adjusts the refrigerant flow inside the AC unit to control the cooling and heating capacity as per requirement.
The speed of the compressor motor is directly proportional to the frequency of the power supply. A variable frequency sensor is used in this unit that controls the speed of the motor.
This motor regulates the flow of the refrigerant inside the unit to provide a proper amount of cooling or heating as required. This eliminates the frequent start and stops cycles. And thereby increases the energy efficiency of the AC unit in the long run.
The inverter technology has been designed in such a way that the AC can save 30% to 50% of the electricity than any other regular air conditioner.
From the year of 2016, BEE (Bureau of Energy Efficiency) has started to provide star ratings to the inverter technology ACs as well.
Below is the defined range of ISEER for Inverter Air Conditioners:
What is a Non-Inverter AC?
A non inverter air conditioner unit comes with a fixed speed compressor motor. Non inverter air conditioner works with the ‘all or none’ principle. It means that the compressor automatically goes on and off rather than running at full speed continuously.
The compressor of the AC unit automatically gets off when the required temperature is reached and it starts again when the temperature enhances. For the frequent on-off cycles, the compressor always functions at high power that creates a lot of noise.
It generates noise when the machine is running and therefore it consumes a lot of electricity.

Inverter AC vs Non Inverter AC
After knowing the definition of inverter AC and non inverter AC we will go forward to the difference between these two types of AC units. We will differentiate the Inverter ACs from the non inverter ACs by their basic features.
Now, we will provide a basic chart to differentiate between an Inverter AC vs Non Inverter AC.
|Aspects||Inverter AC||Inverter AC|
|Compressor motor||Always on||On and Off|
|Reach to desired temperature||Quickly||Takes time|
As Inver AC units run continuously at variable speeds there is no sudden flare in consumption of power. Moreover, as these AC units do not work at full capacity all the time, it consumes less energy.
On the other hand, non inverter AC units consume a lot of energy. In non inverter AC the compressor continuously goes on for the frequent on and off the system.
Therefore, non inverter AC can consume more energy in comparison with inverter AC units.
Now, we will provide a chart of power consumption by both inverter and non inverter AC units so that you can clearly understand the difference.
|No. of Stars||0.75 Ton||1 Ton||1.5 Ton||2 Ton|
|1 Star Non Inverter||627||843||1246||1648|
|2 Star Non Inverter||596||800||1184||1626|
|3 Star Inverter & Non-Inverter||542||747||1104||1448|
|4 Star Inverter||464||645||945||1293|
|5 Star Inverter||450||554||840||1113|
Inverter AC works on a variable speed compressor. It ensures that this AC unit adjusts to the slower speed when the temperature of the room is exact. The compressor speeds up when the temperature increases.
On the other hand, Non Inverter AC works with a fixed speed compressor. It means the compressor makes the room cool with the desired temperature. And cuts off the particular temperature of the room till the room becomes warm again.
Then it restarts the same process.
In Inverter air conditioners as the compressor motor does not go on and off, it does not generate much noise.
On the other hand, in non inverter air conditioner, the compressor motor keeps turning on and off throughout the operation. Therefore, it produces a lot of noise.
As inverter air conditioners work at a maintained speed, it does not have to work very hard. It causes less wear and tear and makes the air conditioner long lasting.
On the other hand, non inverter air conditioner does not work at a maintained speed and gets turned on and off throughout the function.
Therefore, these air conditioners cannot last long compared to inverter air conditoners.
In the inverter air conditioners, the cooling remains even as the compressor never goes off. The room can be maintained at a constant temperature.
Hence, you can take a sound sleep.
In non inverter air conditioner, the cooling is uneven. It happens as the compressor remains in a power off mode until the room warms up significantly.
Inverter air conditioners are comparatively expensive. But this will be a long term investment for you as these air conditioners last long. Moreover, the less maintenance bill, less power consumption, and better performance will surely save a lot of money.
On the other hand, non inverter air conditioners are comparatively cheaper. These air conditioners are also good enough to make the room cool.
People who want an air conditioner in the budget can go for it.
Finally, you can see that inverter air conditioners are a bit more expensive than the non inverter air conditioners. But your one time investment will surely be worth it if you buy an inverter AC.
Moreover, non inverter air conditioners are less reliable and more expensive to manage and maintain.
Hopefully, this detailed difference between the Inverter AC vs non Inverter AC will be helpful for you to choose the best one.
