Difference Between Inverter and Non Inverter Air Conditioner

Are you struggling to choose between the Inverter and a Non-Converter Air Conditioner?

If YES, then keep scrolling further.

This blog covers the key difference between Inverter and Non-Inverter AC. Also, it will walk you through the important things one should consider before buying an Inverter or Non-Inverter Air Conditioner.

Both of these technologies have similar cooling units but the working of the compressor makes a difference in terms of their energy-saving efficiency, performance, and price points.

But before we jump into the conclusions of Inverter Vs Non-Inverter AC, let us quickly understand the technical definitions of both.

What is an Inverter AC?

An Inverter Air Conditioner has a compressor unit that continuously runs on the variable speed to control the cooling condition by regulating the refrigerant flow inside the unit, which means the compressor works efficiently to increase or decrease its output. It works continuously without frequent on-off in the cycles, making it more of an energy-saving unit in the long run.

What is a Non-Inverter AC?

The Non-Inverter Air Conditioner has the compressor unit that functions at controlled speed or turns off. The compressor motor turns off once the room temperature reaches the preset level. These frequent on-off cycles in the unit create unwanted noise at a given time. Eventually, the very often changes into on-off states leads to high energy consumption and power.

Difference Between Inverter and Non Inverter Air Conditioner

Inverter AC

Non-Inverter AC

The compressor unit works at a regulated speed to constantly control the room temp. as desired.

The compressor unit either works at a full speed or turns off, inviting high energy consumption all the time.

It operates quietly without any noise.

The continuous on-off situation results in a lot of unnecessary noise.

The Inverter AC system is for long hours usage with power saving.

They use more electric power than Inverter units.

The installation and pricing are higher in Inverter Systems.

They are available at much cheaper rates in Comparison.

They are more durable and flexible with a longer life span.

The life span on Non-Inverter units is less.

Inverter VS Non-Inverter AC

Compressor Unit

In an Inverter AC, the compressor unit works continuously with a regulated speed setting making it more functional, durable, and flexible in use. The compressor unit of Inverter AC is highly reliable with a longer life span and considered to be an eco-friendly investment where the daily usage is continuous.

On the contrary, the compressor unit in the Non-Inverter AC frequently turning on and off results in early wear and tear of the cooling system. It has a shorter life span compared to Inverter AC compressor units.

Energy Efficiency

An Inverter Unit works at a variable speed to change the room temperature as required. This allows it to conserve the energy as and when necessary, saving up to 20-25% on electricity bills compared to Non-Inverter AC. It makes the Inverter AC a better choice considering its energy efficiency and minimal power consumption.

As the Non-Inverter AC works on the basis of frequent on-off cycles, there are least chances to save on power consumption. For the users, having regular use of 4-5 hours can go for the Non-Inverter option, as the Inverter system is made for the users to benefit from long hours of usage.


The Inverter-AC is a versatile model due to its adjusting cooling system. It will control the refrigerant flow as per the thermostat sensors inside the AC unit. This kind of operational ability makes it win over the performance parameters compared to the Non-Inverter.

However, one must consider other factors before choosing between the two systems.

Price Range

The Inverter AC falls in the expensive price range as it is meant for a long term investment. Also, it uses more advanced technology for you to save some money on the electricity bills in the long run. The installation charges including the mechanical parts are expensive as compared to the Non-Inverter type.

The biggest advantage of Non-Inverter AC is that it is available at cheaper price points than the Inverter AC. But, one can debate it with the electricity bill savings in the future!


As the Inverter AC compressor works at a controlled speed, the unit functions as per the room temperature rather than sudden on and off. This option can avoid you from the loud start and stop sounds.

The Non-Inverter Compressor unit makes a lot of noise due to on-off cycles to reach the desired room temperature level. These abrupt on/off in the compressor make you feel hot or cold followed by unwanted noise.

Having said that, it doesn’t make a big difference and not very much noticeable all the time.


I hope this blog helped you in understanding the fundamental difference between Non-Inverter and Inverter AC.

The final decision of choosing between Inverter and Non-Inverter AC is influenced by various factors like hours of daily use, location (i.e. home, office, shop), and most importantly your budget.

    I thinking nowadays the price difference is not much between both the type of ACs and considering the advantages of Inverter AC, I think one should always opt for an Inverter one.
