Inverter Vs Non-Inverter Air Conditioners – Rays Electronics

You may have heard of two types of air conditioners – inverter and non-inverter – when it comes to buying one for your home or office. Both of these types of air conditioners differ not only in appearance and operation, but also in terms of effectiveness, power usage, and cost. In order to help you make an informed decision and select the best air conditioner for your needs, we will examine all you need to know about inverter vs. non-inverter ACs in this article.

What is an Inverter AC?

Inverter AC

A form of air conditioning system called an inverter AC, sometimes referred to as a variable-speed AC, employs a variable-speed compressor motor to control the room’s temperature. Instead of turning on and off like a non-inverter AC, the inverter AC operates by continuously regulating the speed of the compressor motor to maintain the required temperature.

A built-in inverter circuit in the inverter air conditioner regulates the speed of the compressor motor dependent on the ambient temperature. The inverter circuit raises the speed of the compressor motor as the room temperature rises, which results in additional cooling. In contrast, the inverter circuit slows down the compressor motor when the room’s temperature rises, resulting in less cooling.

What is a Non-Inverter AC?

Non-inverter air conditioners, sometimes referred to as fixed-speed air conditioners, employ a fixed-speed compressor motor to control the room’s temperature. The compressor motor is turned on and off by the non-inverter AC to maintain the correct temperature. The non-inverter AC activates the compressor motor as the room temperature rises, which results in cooling. The non-inverter AC turns off the compressor motor when the room temperature dips, which reduces cooling.

Difference Between Inverter AC and Non-Inverter AC


Efficiency is one of the key distinctions between inverter and non-inverter AC. Compared to non-inverter ACs, inverter ACs require less energy to maintain the desired temperature. Inverter ACs adjust the compressor speed according to the room temperature, whereas non-inverter ACs work at a fixed speed, which results in more energy consumption.


Since they don’t need to repeatedly turn the compressor motor on and off, inverter air conditioners are quieter than non-inverter air conditioners. Less noise is produced by inverter ACs because they operate at a constant speed. On the other hand, non-inverter air conditioners generate greater noise since the compressor motor needs to be turned on and off more frequently.


AC units with inverters are more expensive than those without. However, inverter ACs use less energy, which can ultimately result in cost savings. While non-inverter air conditioners are less expensive, they use more energy, which may lead to higher electricity costs.

Cooling Speed

Comparatively speaking, inverter air conditioners chill a space more quickly. Faster cooling results from inverter air conditioners adjusting the compressor speed in accordance with the ambient temperature. Non-inverter air conditioners operate at a fixed speed, which slows cooling.


Compared to non-inverter ACs, inverter ACs need less maintenance. Because the compressor motor does not have to work as hard, inverter air conditioners have longer lifespans and experience less wear and tear. Non-inverter air conditioners need additional maintenance, which increases compressor motor workload and potential for wear and tear.

Which one to Choose – Inverter or Non-Inverter AC?

Depending on your needs and budget, you can choose between inverter and non-inverter air conditioners. An inverter air conditioner should be taken into consideration if you’re looking for a system that can cool the space more quickly, quietly, and efficiently. But if money is tight and you don’t mind the noise and slower cooling speed, a non-inverter air conditioner might be the best option for you.

Additionally, a non-inverter AC should be taken into consideration if you reside in a region where power outages are frequent because it can operate for a brief period without electricity. Inverter ACs, on the other hand, depend on a steady power source and could not work correctly when the power is out.

The size of the room is another vital consideration. Larger rooms are better suited for inverter air conditioners since they are more effective at maintaining a constant temperature. On the other hand, non-inverter air conditioners are better suited for smaller spaces because they are more affordable and capable of providing appropriate cooling.
