Obviously, the “yield” in terms of freshness and less important than with an air conditioner … which can quickly become an energy -consuming luxury. Used continuously overnight, it can increase the electricity bill of € 35.67 for a model of 1,000 W to € 71.35 for a device of 2,000 W.
In summary, the monthly cost of a fan can be spent overnight, using an air conditioner. Figures that are based on the price of electricity on the market in July 2025.
How to avoid overconsumption?
For those who want to avoid a unpleasant surprise on their invoice, Callmepower recommends limiting the use of air conditioning, programming it or turning it off at night after refreshing the room. In addition, simple gestures allow you to stay cool: close shutters and curtains during the day, ventilate in the morning or evening, hang a damp sheet in front of a window, or even vegetate its exterior.
Finally, comparing energy offers remains essential to lighten the note, recalls Callmepower. “An adapted contract can make the difference, especially during periods of high consumption.”
We also recall that using an air conditioner when you have solar panels will not have the same effect on the energy bill. And with a dynamic contract? It will be a question there of turning it during the day, during off -peak hours, but especially not in the evening and at the start of the night.
