How much electricity does the air conditioner consume?

Over the past ten years, split systems have been significantly improved, including in terms of energy consumption. However, there is still an opinion among buyers that these devices can significantly increase electricity bills, despite the modest power of home air conditioners.

How much energy do air conditioners consume? What is the optimal power consumption per hour? Which air conditioner should I buy to reduce my electricity consumption? We will answer these and many other questions in this article.

Calculation of electricity consumption per month

The power of household air conditioners, as a rule, does not exceed 3-4 kW. Usually buy an air conditioner with a power of up to 2 kW. This is enough to cool or heat a room with an area of up to 20 square meters. If the size of the room does not exceed 10 square meters, purchase a device with a power of up to 1 kW. So you can save on electricity.

Let’s calculate how much it will cost to use an air conditioner. As a basis, we will take an air conditioner with a capacity of 2 kW, which is how much kW per hour the device will consume. Let’s assume that it’s a hot summer outside and the air conditioner is used 10 hours a day.

air conditioner power selection

Multiply 10 kW by 2 kW and get 20 kW. So we will find out what is the power consumption of the air conditioner in one day. Let’s assume that the machine is used daily. Multiply 20 kW by 30 days and get 600 kW / month. Multiply this value by the cost of one kW in your city and get the total cost of using the air conditioner.

Please note that this is only an approximate calculation. We did not take into account the windows, doors, type of device (for example, inverter conditioner consumes less electricity than normal), operating mode, and other factors. So when working in the heating mode, the power consumption will be greater than when cooling.

However, these calculations are enough to find out an approximate figure and understand how much air conditioners consume electricity per hour, and whether you can afford to own such a device.

How to reduce energy consumption?

If you have not yet purchased the device, pay attention to the economical air conditioners of the inverter type. Their power should not be high (up to 1.5 kW), and the energy consumption class should not be lower than «A».

air conditioning for homes and apartments

Have you already bought the device and installed it? Follow our tips to reduce your air conditioning power consumption:

  • Do not open the windows during operation of the air conditioner. If you want to ventilate the room, turn off the air conditioner;

  • Set the temperature to no more than 25 degrees. When the temperature rises or when using the device in heating mode, air conditioners spend more electricity;

  • Maintain the air conditioner regularly. Some work can be done independently. For example, to clean or replace filters. The dirtier the filter in your split system, the more electricity the air conditioner consumes, as you set an increased air purification mode.

Conclusions

In this article, we tried to explain in detail how much electricity is consumed by air conditioners and what is the optimal power consumption. On average, air conditioners consume 2-3 kilowatts per hour.

Of course, this figure is approximate, since only a specialist will be able to accurately answer the question of how much your chosen air conditioner model consumes in your home. If desired, the power consumption can be reduced.
