How to choose an air conditioner for your home

Which air conditioner is better to buy: inverter or conventional?

Inverter and non-inverter air conditioners are equally represented on the market. Because of this, buyers can not decide on the purchase. The cost adds fuel to the fire: for some reason, a conventional air conditioner is cheaper than an inverter one.

Ordinary non-invertor air conditioners are familiar to us from the last century. They work stably at a positive temperature outside the window, with a basic set of functions, they are inexpensive and familiar to every master. However, they are not perfect, and this is one of the reasons why the market there were inverter air conditioners.

In this article, we will tell you in detail how inverter air conditioners differ from non- inverter ones and what nuances should be taken into account.

General information

The key difference between an inverter device and a non-inverter device is the features of its operation. This is the key difference.

A conventional air conditioner works on a special principle: it turns on at full power, cools the air to a set temperature and automatically turns off. At the same time, the built- in sensor responds to a gradual increase in the temperature in the room, and if it rises above the set point, the air conditioner turns back on at full power and runs until the air temperature drops. This is a cyclical process.

The inverter air conditioner operates continuously. It keeps the temperature constant , but the compressor is not running at full capacity.

Conventional air conditioning was produced in the last century, and the inverter came to the market only in the 21st century. Previously, inverter air conditioners were very, very expensive, so do not they were popular among the mass consumer.

Over time, the cost has significantly decreased and now these devices are available to everyone.The largest manufacturers of split air conditioning systems are gradually switching to an inverter system, abandoning classic technologies. Why? Let’s figure it out.

Key features of the inverter air conditioner

So, the main difference between inverter air conditioners from conventional ones is in the different operating mode. The inverter unit operates continuously and at medium power, and the normal one- intermittently, but at maximum power. This implies a number of features that inverter air conditioners have.

Let’s look at them in more detail:

  • Energy efficiency. Inverter air conditioners optimally consume electricity. This means that after buying an air conditioner, your bills for utilities will increase slightly. A regular machine that works on classic technology, consumes a lot of electricity. Because of this, there is a myth that air conditioners are expensive to operate;

  • Quiet operation. If you can’t decide which is better — inverter air conditioners or normal,pay attention to the volume of the device. Inverter type the air conditioner is quiet and produces no more than 20-40 dB of noise. Conventional air conditioning it works quite noisily, it can not be installed in the bedroom or office;

  • Reliability. Inverter air conditioners do not work at full capacity, so their compressors last significantly longer than conventional machines;

  • Operating temperature range. The inverter unit is able to work even at sub -zero temperatures outside the window, which means that you can use it in the mode of heating of the air (if this function is provided). The air heating function is especially useful in the off-season, when the heating has not yet been turned on, but the house is already cold.

  • Cost. Due to its advantages, the inverter air conditioner is more expensive than usual. It is difficult to call it a budget, decent inverter devices will cost 500 dollars or more.


Now you know the difference between inverter or conventional air conditioners. The main difference from the ordinary one is the compressor. It runs continuously, so the air conditioner keeps the temperature constant. Inverter devices are more reliable, more energy efficient and… more expensive.

Which air conditioners are better? Which ones to choose? It’s up to you. If energy efficiency, functionality and reliability are important to you, we recommend purchasing an inverter air conditioner. If the budget is limited and there are no high requirements for the operating mode, then a regular air conditioner is the best choice.
