The cost of consuming the air conditioner depends on several factors. There is the model of the air conditioner, the set temperature, the starting temperature and also the way in which the rooms we want to refresh are built. In this article you will find all the factors to better understand the functioning of the air conditioners and a little advice to better manage consumption.
The heat started. Red sticker city, illness related to high temperatures and also a new protocol for the heat signed by the Ministry of Labor. The air conditioners have started working again. The days of the first blackouts were also in this heat wave. In Google’s searches, a question has returned to make their way: How much does an hour of air conditioner cost?
We immediately give you one good news. It costs less than recent years. In the’August 2022 the value of the Pun, the unique national price, was set to 0.543 €/kWh. In the’August 2024 was a 0.128 €/kWh. Now it has come down a few cents. According to A2A in June 2025 has come to 0.111 €/kWh. A fact therefore that (with the same consumption) should lower the average expenditure to the bill. According to a research by Facile.it throughout 2024, Italian families have spent on average 791 euros for the light bill: the 6% less compared to 2023.
How much the air conditioner consumes every hour: the cost of air conditioning
Consumption of air conditioners vary according to many factors. There is the model, first of all. Different models may have different consumption. Just as more recent models can have different consumption from older ones. But not only. Consumption of the air conditioner also change based on the rooms we want to cool, at the temperature outside the arrangement of the furniture and the ecological class of the house where the air conditioners are installed. Let’s say that an on average conditioner can consume between 0.3 and 1.5 kWh at the then. We really hold the data we have while writing the article. The 4 July 2025 the cost of an hour to condition in the F1 time slottherefore during the day, it can vary between 5 and 25 cents. The cost of a €/kWh is 0.17301.

The role of BTU: what they are and why they affect the cost of air conditioning
The BTU It is one of the most important values to consider when you have to choose an air conditioner. We are talking about a unit of measurement, specifically the acronym stands for British Thermal Unit. BTU are measured the air conditioner’s ability to bring fresh air into an area. The higher the number of BTUsthe more powerful the air conditioner is. Knowing how many BTU is able to generate an air conditioner is used to understand which model to choose to install. Obviously a lot is linked to the size of the room to be refreshed. To calculate how many BTU are used to refresh an environment there are various ways.
In portals specialized in appliances we often find a formula to follow: BTU = sqm xk. To understand how many BTUs we need for a room we have to take the number of square meters that measures a room and multiply them by the coefficient K: it is a value fixed to 340. More simply said: 340 are needed to refresh each square meter. More m2 we have, the more BTU serve, the more energy is necessary.
How to understand the energy class of the air conditioner: how to read the label
To understand the energy class of an air conditioner we must read it was his energy label. The parts that interest us are two. The first is the division of energy classes, which goes from A *** a d. Obviously the higher the class, the more efficient our appliance is. The second is the value indicated how many kWh are needed every 60 minutes: will help us do the calculations we have seen above.
