Difference Between Inverter Vs Non-Inverter AC

When buying an air conditioner, what is the first feature that people usually look for?

The inverter or non-inverter feature is considered at the top in all the factor lists, so learning about it in detail is crucial. Even though it seems as if there is a single difference between the inverter and non-inverter air conditioners, in reality, these two types are very much apart from each other. That’s why in this following article, we will highlight the differences while explaining their pros and cons. With this guide, you will finally have the clarification needed to decide which type of appliance will be suitable for you. 

What is an inverter air conditioner?

Air conditioners work on alternating current just like other appliances. Since alternating power supply can have sudden spikes or ups and downs in the voltage and current signal, these will have a lot of impact on the compressor and motor of the air conditioners. However, if an inverter is added, it will adjust the current flow and its voltage according to the functioning of the motor and compressor or the cooling efficiency. It helps convert the alternating current into a direct current and vice versa. Therefore, no extra energy expenditure will be there with the inverter ACs. 

What is a non-inverter AC?

In the non-inverter ACs, there is no such technology that can convert the AC into DC or the DC into AC. Therefore, the current that flows through the circuit is alternating in type, and hence, consumption of the power remains the same, no matter whether the compressor is being operated at the lowest speed or the highest one. Therefore, there is no control over energy consumption, so the utility bills always remain high. 

Benefits of inverter AC

  1. Since It can convert the alternating current into direct current and vice versa, the AC’s compressor won’t work fully. Therefore, it will control the current and voltage at the proper limit required to cool down the room’s air. 
  2. As a result of the inverter technology in the air conditioner, the energy consumed will be low since compressors will adjust the speed and other attributes based on the cooling settings.
  3. The inverter air conditioners do not make a single sound because the current coming into the appliance is DC. Therefore, there won’t be any voltage fluctuations, and the brushless motors can work perfectly. 
  4. It is highly durable and won’t cause the AC much damage for a long period. Thus, there is no need to buy the same appliance once again just because the old one is not functioning properly, in the usual manner. 

Benefits of non-inverter AC

  1. The non-inverter air conditioners are cheap and usually come within a price range of INR 25000. Therefore, these are perfect for people who have a borderline low budget.
  2. These air conditioners are smaller in size, and hence, you won’t have to consider a lot of area in the room. 
  3. Cleaning the non-inverter air conditioners is much easier, and you won’t need a professional to do the same job. 
  4. You can maintain the compressor easily, and even a normal electrician can fix any issue if there is a malfunction in your appliance. 

Disadvantages of inverter AC 

  1. One of the biggest disadvantages of the inverter air conditioners is extremely costly. And therefore, if you have a low budget, it will become quite difficult to get this particular technology for yourself.
  2. Also, it is very important to have a voltage stabilizer in the inverter air conditioners to control the spikes easily. 

Disadvantages of non-inverter AC

  1. The non-inverter air conditioners consume a lot of energy, and that’s why your utility bills will come in huge amounts every month. Moreover, this particular appliance type is not at all eco-friendly. 
  2. Besides, they need frequent maintenance because the compressor coils can easily get damaged due to overheating from excessive current flow.
  3. Another major disadvantage of the non-inverter air conditioners is that they can make loud noises since there are no brushless motors. 
  4. The durability of the internal circuits in the non-inverter air conditioners is lower than the inverter ACs. 

Inverter VS Non-inverter AC – which one should you get?

Now that you know the benefits and disadvantages of both the inverter and non-inverter air conditioning technologies, you have at least some clarifications. However, if we ask you to make an immediate choice, you will certainly struggle a lot. That’s why in this below section, we have explained how you can choose the appliance type based on the compressor technology. 

1. Noise 

Suppose you are buying an air conditioner for your bedroom. In that case, we suggest going with the inverter air conditioners because they don’t make much noise. And therefore, your beauty sleep won’t get disturbed. On the other hand, the non-inverter ACs can make whirring noises due to the motor rotation. Hence, the ambience will get disturbed, and you may feel irritated and frustrated.

2. Electricity consumption 

If you want to save money on your utility bills, it is best to go with the inverter air conditioners. As the electric consumption is optimized as per the function of the compressor, the current flowing through the coils will vary, thereby reducing the bills. On the contrary, the non-inverter air conditioners will most certainly increase the utility bills as the current consumed remains uniform throughout the entire time you operate the appliance. 

3. Durability

The inverter air conditioners are highly durable and can last for a long time. That’s why they are ideal for domestic purposes since you will be using the appliance almost throughout the day in the summer season. However, in places where the appliance will operate only for a couple of hours, we would suggest getting the non-inverter air conditioners. 

4. Cost 

Cost is also a major factor that you need to consider when deciding whether you want an inverter AC or the non-inverter one. If your budget is below INR 30,000, you need to get the non-inverter products as they are much cheaper and are available within this price range. But suppose you do not have a borderline or restricted budget. In that case, you can go for the inverter air conditioners because they will cost you more than INR 30,000. 

5. Maintenance 

Suppose you do not want the hassles of frequent maintenance and repairs of the air conditioners. In that case, you need to choose the inverter technology. This new form of compressor doesn’t need much maintenance work, and therefore, you won’t have to waste time and money. But, on the other hand, the non-inverter air conditioning technology will require a lot of maintenance and therefore, you need to deal with huge expenses. 

6. Efficiency 

Suppose we judge the appliances based on efficiency or performance. In that case, it is pretty much obvious that the inverter technology will be the winner. These air conditioners can cool down the temperature and maintain the temperature at the required level. On the other hand, performance-wise, the non-inverter ACs won’t be the ideal choice. 


This article has discussed everything you need to know about the inverter and non-inverter air conditioners. Thus, you can now make the right selection. First, however, make sure that the appliance has all the features you are looking for, regardless of whether you have chosen the inverter or the non-inverter AC. Another thing that we would like to end before winding up this discussion is that for domestic purposes, the inverter ACs are more suitable, while for commercial purposes, you can get either the inverter or the non-inverter appliances as per your budget range.
