Do you want to turn on the air conditioner at this temperature of about 25℃ tonight?

When the outdoor ambient temperature is 25℃, if the outdoor air quality is good, it will be more comfortable and healthy to open the doors and windows for ventilation.

Whether you can turn on the air conditioner depends entirely on your own needs. For example, Europeans are used to turning on the air conditioner 24 hours a day, regardless of whether the outdoor ambient temperature is two degrees higher or two degrees lower.

From the point of view of pure economy, it is completely unnecessary to turn on the air conditioner when the outdoor environment is 25℃.
