Running Costs: The harder your air conditioner has to work, the more energy it consumes. Setting to a high of 30 degrees in winter or a low of 18 degrees in summer may seem appealing, but it won’t be efficient. The additional energy required to achieve these results would cost more money than if you had settled for a comfortable middle ground.
