In most cases, the biggest worry when installing or configuring a new air conditioner is how it will impact the monthly bill. Energy use in a home can spike quickly, and every euro counts. The goal is to optimize cooling without letting costs spiral out of control.

To keep expenses in check, consider machines that include smart features. A presence sensor, for instance, adapts cooling based on whether someone is in the room. This technology is common in offices and meeting rooms where devices are often left running when spaces are occupied. If no one is detected, the unit can switch to an economy mode or raise the set temperature to save electricity. The exact behavior depends on the model.
If a unit detects activity in a room, it adjusts to comfortable temperatures; when the room is empty, it conserves energy. Modern air conditioners vary widely in how they implement these modes, so it’s worth checking the specifications for each model.
