Calculating how much an air conditioner on all day consumes is not easy. It is not a single variable, so different data must be taken into account. On the one hand, you have to know what kind of device we have. You also have to know the price of electricity, as well as the temperature at which we are going to put it, the previous temperature, the size of that room… However, we are going to give an approximate figure so that you can get an idea.
It should be mentioned that air conditioning is one of the devices that can consume more electricity in summer. When the temperature rises, it is our best ally. But of course, that is reflected in the electricity bill and we may look for alternatives or methods to try to reduce consumption.
Air cost all day post
We are going to assume that you have an air conditioner in a room that is not excessively large and it is a modern device, so the consumption will not be excessive. We can find models that have a power of between 1000 and 2000 Wh. That consumption will be at 100% performance, which is basically when we turn it on and the temperature begins to drop.
If we have a model that consumes 1500 Wh to the maximum, for example, when it reaches the temperature, that expense will decrease. In fact, if it is an inverter air conditioner, it can even drop by approximately 70%. Let’s assume that it consumes 500 Wh once it reaches temperature (there are more efficient ones and they can even use 200-300 Wh). Of course, it is key that you have a correct temperature, since otherwise consumption may increase. We are talking about having the air at around 24-25 degrees.
You must also calculate the time it will take to reach the desired temperature. It will depend on what the previous temperature is, the thermal insulation that that room has, the power of the air, etc. We can calculate, for example, a couple of hours. Of course, it does not mean that you spend those first two hours consuming 1500 Wh, but rather that it will gradually decrease. It is complicated to calculate. Let’s say that the first hour does consume 1500 Wh, but then the second goes down to 800 to, from there, keep it stable at 500 Wh.
What does it mean to put the air conditioning on all day? Maybe you put it only during the hours that you are working, eating and living at home. When night comes, you may decide to turn it off. Let’s assume you keep it on for 12 hours. The total consumption will be, according to our example, 7300 Wh or 7.3 kWh.
You will have to know what the kWh price is, which will depend on your rate. It is not the same to have a rate with hourly discrimination, in which it will cost you more or less depending on the time of day, than another with a fixed price regardless of when it is. We are going to put ourselves in this last case and we are going to set a price of €0.16 per kWh.
In this case, the consumption for those 12 hours with the air conditioning on would be approximately €1.17. If you had more hours, you would simply have to recalculate the total expense in kWh and do the math. If you are going to turn on the air throughout the month, always at the same time, the cost would be around €35 ​​in total.
As you can see, with this simple account that we have explained, you will be able to know how much your air conditioning spends all day on. Of course, you must take into account that each model is different, also the temperature at which you put it, the price of electricity according to your rate, etc. However, you can get a rough idea.
