Split systems

What is an inverter air conditioner?

When choosing a household split system, it is important to take into account many parameters: power, form factor, functionality, and much more. The technical specifications of any air conditioner indicate all the information that you should read before buying. Among the characteristics, it is often indicated that the device is an inverter.

In this article, we will briefly describe what an inverter air conditioner is, what are its advantages and disadvantages, how it differs from a conventional non-inverter air conditioner, and what nuances need to be taken into account.

General information

The inverter-type split system is designed on the basis of a conventional split system, but has been slightly upgraded.

To understand how inverter air conditioners work, it is enough to recall the principle of operation of a conventional split system. It consists of two blocks (external and internal), between which the refrigerating agent circulates.

Both an inverter and a traditional air conditioner consist of a compressor, condensers, choke, and other components. In both cases, thermal energy is used to convert the refrigerant from a liquid state to a gaseous state and vice versa.

But what is their difference, if the structure and principle of operation of the inverter air conditioner is so similar to the traditional one? Let’s figure it out.

How is it different from a regular air conditioner?

To understand what an inverter air conditioner is, remember only one feature — an inverter and a traditional air conditioner are built and operate on the same principle, but the operating mode is controlled differently.

This is the key point: in the inverter air conditioner, the operation mode control has been significantly improved. The inverter device transfers heat on the same principle as a conventional one, but it does it more efficiently.

Regular air conditioning works intermittently. First, it performs a cycle of circulation and conversion of the refrigerant from one state to another at full power, and then it turns off. A special sensor reads the room temperature, and if it rises by 3-5 degrees, the system will automatically start, and turn off again when it reaches the set temperature.

Inverter split systems operate continuously. The circulation of the refrigerating agent stops only when you press the switch-off button of the machine. At the same time, the inverter air conditioner does not work at full capacity, but maintains the same temperature for a long time.

Simply put, your wall-mounted split system of the inverter type does not allow significant fluctuations in the room temperature, whereas a traditional air conditioner can allow a change in the air temperature within 3-5 degrees.

Advantages and disadvantages of inverter air conditioners

If you are not sure which device is worth buying, check out the pros and cons of inverter air conditioners.

Let’s put aside the marketing tricks and focus on the real merits:

  • Stable indoor temperature

This is what we talked about earlier. The inverter air conditioner does not allow significant temperature changes in the room during operation. You just set up the device and enjoy the comfort;

  • Energy saving

Conventional split systems consume 30% more electricity because they operate at full capacity. Hence, the myth that the owners of air conditioners pay large utility bills grows. Inverter devices use energy more economically;

  • Reliability and maintainability

The compressor in the inverter air conditioner works continuously, frequent starts and voltage drops are practically excluded. Accordingly, the compressor lasts longer, and this is the heart of the air conditioner;

  • Low noise level

Inverter-type air conditioners work quietly, and there are [special models with a reduced noise level on sale, which are designed specifically for the bedroom or study.

  • Efficient air heating

The split system can work both for cooling and heating. Inverter devices do an excellent job of heating the air even if the window is -10 degrees, but you are unlikely to use it in this mode;

Now about the disadvantages:

  • High cost

Inverter and conventional air conditioning significantly differ in price. Manufacturers set the price for an inverter split system by 30-40% more than for a conventional one. Also note that if the inverter air conditioner still breaks, you will face expensive repairs.

  • Small selection

Another drawback is the small variety of form factors. Often, inverter split systems are wall-mounted air conditioners. On sale there are also channel air conditioners of the inverter type, but they are too expensive compared to a conventional channel air conditioner.


Now on the market there are inverter and non-inverter air conditioners. Before you make a choice in favor of a particular device, carefully read its technical characteristics.

In this article, we tried to briefly describe what an inverter air conditioner means, what its pros and cons are. Buy or not-it’s up to you. If you have used an inverter air conditioner before, please share your impressions in the comments below. Good luck!
