Differences Between Inverter AC and Non-Inverter AC; Advantages and Disadvantages

Modern houses and businesses are packed with air conditioners, which offer much-needed relief from the summer’s scorching heat. Air conditioning systems have improved in reliability, efficiency, and quietness as a result of technological advancements.

The introduction of inverter air conditioners is one of the most important technological developments in this industry. In this article, we’ll explore the key differences between inverter AC and non-inverter AC and each type’s advantages and disadvantages. We’ll also consider which kind of air conditioner would be the most suitable for your needs.

The fundamental concept behind air conditioning is to move the heat from a room to outside. This is done by moving refrigerant gas back and forth between the AC system’s indoor and outdoor units.

The heat from the inside air is taken up by the refrigerant, which then transfers it outside where it is released into the atmosphere. Until the desired temperature is reached, this procedure is done repeatedly. How well the AC system can complete this heat exchange process determines its efficiency.

How Non-Inverter AC Works?

The more common type of air conditioning system is the non-inverter unit. To control the compressor’s speed, they use a simple on/off mechanism. The compressor turns on at full power until the target temperature is reached when the room temperature increases above the specified point.

When the desired temperature is reached, the compressor entirely turns off. Every time the room’s temperature changes, this process is repeated. A non-inverter AC compressor only has two settings: full power and no power. As a result, it has to exert more effort to reach the necessary temperature, which raises the rate at which energy is consumed.

Advantages and Disadvantages of Non-Inverter AC


  • less expensive upfront than inverter air conditioners.
  • good for smaller spaces with less temperature variation.
  • simple to maintain and repair.


  • High electricity use and power costs as a result of the continuous on/off cycle.
  • The compressor’s rapid starting and stopping makes it louder than inverter ACs.
  • less effective at high temperatures.

How Inverter AC Works?

The newest and most advanced form of air conditioning system is the inverter unit. They control the compressor’s speed using a variable frequency drive (VFD), which enables it to adjust its output according to the room’s temperature.

Depending on the need for cooling, the VFD can adjust the compressor’s speed anywhere from 10% to 100%. As a result, the compressor doesn’t have to operate continuously at full capacity, which reduces both energy use and electricity costs.

Advantages and Disadvantages of Inverter AC


  • The variable compressor speed makes it energy-efficient.
  • Because the compressor starts and stops more smoothly, there is quieter operation.
  • More effective in extreme temperatures.
  • Maintaining a constant temperature.


  • higher up-front cost compared to Non-inverter ACs.
  • More complex and costly to maintain and repair.

Inverter AC vs No-Inverter AC Which one is Best?

The choice between an Inverter AC and a non-inverter AC depends on several factors, including the size of the room, the frequency of use, and the budget. For larger rooms or areas with extreme temperature fluctuations, inverter ACs are a superior option.

Since they are more energy-efficient as well as provide better temperature adjustment. Additionally, they cost more upfront and require more maintenance and repair costs over time. Non-inverter ACs are cheaper to buy and maintain, making them a good choice for smaller rooms or areas with minor temperature fluctuations.

Compared to non-inverter air conditioners, inverter air conditioners are the more modern and energy-efficient option. They provide better temperature control, are quieter, and perform better in extreme temperatures. They do, however, also cost more upfront and require more maintenance and repairs over time.

Non-inverter air conditioners are less expensive and require less maintenance, but they use more energy and are noisier than inverter ACs. The buyer’s specific needs and budget restrictions will decide whatever option they choose.

It is important to understand that an AC system’s overall efficiency does not only depend on whether it uses an inverter or a non-inverter. The effectiveness of an AC system is also strongly affected by other elements, like the type of refrigerant used, the size of the room, and the quality of the insulation. Therefore, it is important to consider each of these aspects when choosing the ideal AC system for your house or workplace.

Finally, inverter and non-inverter air conditioners each have advantages and disadvantages. Although inverter air conditioners are more expensive initially and require more maintenance and repairs, they are more effective and provide superior temperature control.

Non-inverter ACs are cheaper and easier to maintain but have higher energy consumption and are louder than inverter ACs. It is crucial to take into account all the variables and select the AC system that best meets your needs and budget.

Inverter AC vs Non-Inverter AC FAQs

Which AC is better inverter or non-inverter?

The Inverter AC is better than non-inverter AC because it is more energy efficient and smoother in operation.

What is the disadvantage of inverter AC?

The inverter ACs are expensive than the non-inverter ACs and their maintenance and repairs are also costly.

Should I buy AC with an inverter or without?

It is recommended to go for an inverter AC because it offers good value for money.

Which type of AC is best for your home?

Inverter ACs are best for home because they work smoothly and consume less electricity as compared to Non-inverter ACs.
