Providing a refreshing coolness in summer and gentle warmth in winter thanks to its reversible system, an air conditioner undoubtedly brings a significant improvement in indoor comfort and quality of life. Installing an air conditioner offers substantial thermal comfort in every room, especially in the hottest regions. During heatwaves, it becomes a lifesaving device for vulnerable individuals, helping them avoid extreme temperatures. An air conditioner is not only useful in summer — a reversible AC is also very pleasant in winter, warming the different rooms of the house. However, many questions arise regarding the energy consumption of an air conditioning system.

But precisely, how much energy does an air conditioner consume? For many people, air conditioning is seen as an energy-hungry system that can significantly increase the electricity bill. Before considering having one installed in your home, it is strongly recommended to take into account the air conditioning consumption, as well as the best practices to optimize both its use and its energy efficiency. So, what is the energy consumption of an air conditioner? Discover the best answers in this article, carefully prepared for you by the FrigoTech team!

Air Conditioning Consumption: What Budget to Expect?

In the context of global warming and rising electricity prices, the question of air conditioning costs often comes up. At first glance, an air conditioner can be an energy-hungry appliance, and its use can easily increase the electricity bill. However, the impact on energy costs depends on the device’s power, the rate charged by the electricity provider, and also the way and habits in which the air conditioner is used.

The Power of an Air Conditioner

The kWh, or kilowatt-hour, simply represents the amount of kilowatts consumed in one hour. It is a unit of measurement corresponding to the energy consumed by a device with a power of 1,000 watts (or 1 kW) when used continuously for one hour. For example, an air conditioner with a power of 2,000 watts used for one hour consumes 2 kWh. If the same air conditioner is used for 30 minutes, it will consume half, or 1 kWh.

Air Conditioning Consumption Calculation

To determine how much an air conditioner consumes, you need to take into account the electrical power of the air conditioner in watts, the number of hours the air conditioner is used per day, and the number of days the air conditioner is used over a given period.

Thus, to calculate air conditioning consumption, these elements are multiplied together, using the following formula:

Consumption in kWh = [(appliance power in watts ÷ 1000)] × (number of hours of use) × (number of days of use)

Here’s the English translation:
And to determine how much an air conditioner costs, you then need to multiply this kWh consumption by the price per kWh charged by your electricity provider.

Example

Suppose we want to calculate the consumption of an air conditioner with an electrical power of 2,500 watts, operating 6 hours per day throughout the summer, for example, 3 months or 90 days.

We then have: (2,500 watts ÷ 1000) × 6 × 90 = 1,350 kWh.

Now suppose we consider the EDF Blue Tariff (regulated rate) at €0.2062 per kWh for the price of electricity.

We then have: 1,350 kWh × €0.2062/kWh = €278.37.

Thus, an air conditioner with an electrical power of 2,500 watts will consume 1,350 kWh over the entire summer, with a cost of €278.37.

The type of air conditioner can also affect energy consumption

Split, single-split, multi-split, portable, reversible… there are several types of air conditioners. The single-unit (monobloc) air conditioner is one of the least expensive on the market. Easy to install, it consists of a single unit placed inside the home. With a multi-split air conditioner, one part is inside and another part is outside the home. A portable air conditioner, placed on the floor or on wheels, is a mobile device and is the most affordable financially. As for the reversible air conditioner, it has two modes: cooling and heating. Used for both cooling and heating, a reversible AC can be monobloc, split, or portable.

Here’s the English translation:
An air conditioner equipped with a temperature control system can further reduce your electricity bill. Temperature regulation is a feature that allows the air conditioner to automatically go into standby mode based on the desired temperature or the ambient temperature.

Additionally, it is important to consider the energy label if you want to save on air conditioning consumption. This label reflects the ratio between the air conditioner’s power and its energy consumption. The higher the rating, the lower the consumption. Air conditioners are classified into seven energy classes, ranging from A+++ to G. The energy class of an appliance is indicated on its energy label. Therefore, it is wiser and more cost-effective to purchase an appliance with an A+++ energy label (the least energy-consuming), even if it is slightly more expensive to buy.
