FACT!

In the summer, many people go in search of cooling. A good option is to purchase an air conditioning system. But then the question often comes up: the air conditioner on all day or not?

One of the biggest myths is that it would be more energy-efficient to leave your air conditioner on all the time in your home instead of using it only during the hottest times of the day. This is not true! Heat always seeks cooler places until an equilibrium is reached. The greater the temperature difference between inside and outside, the harder the air conditioner has to work to maintain the set temperature.

For example: if it is 30°C outside and your air conditioner is set to 22°C all day, it keeps running continuously to maintain this difference. This costs an unnecessary amount of energy. A smarter way is to turn on your air conditioner shortly before you get home. This can easily be done with a timer or smart control via an app.

Note: It is wise not to make the temperature difference between inside and outside greater than 6°C. This prevents excessive load on the air conditioner and ensures a pleasant indoor climate without excessive energy consumption.

4 tips to reduce the power consumption of your air conditioner

1. Choose an air conditioner of the right size that fits the space to be cooled. Bigger is not always better. On the contrary: an oversized unit will use more energy than necessary and can even lead to humidity problems.

2. Consider purchasing a model with a timer function. By setting the timer at times when no one is home or at night when it gets cooler, you can save quite a bit on electricity. For example, Daikin models come with WiFi for remote control.

3. Perform regular maintenance to keep the unit operating efficiently. Change the filters from time to time and clean other parts as well. This will make your air conditioner work less hard to cool the room and extend the life of the system.

4. Apply extra insulation around windows and walls. This will make warm air less likely to enter the house during hot days.

Air conditioner on all day or not? Here’s the smartest choice

Unsure whether to leave your air conditioner on or turn it off? The best choice depends on your situation. If you will be away from home for long periods of time, it makes more sense to turn off the air conditioner and only turn it on when you get home. Modern air conditioners with inverter technology adjust automatically and use less energy than traditional models. If you are home during the day, you can reduce energy consumption by setting the temperature no lower than 24°C. Thus, ”air conditioner on all day or not?” does not have to be a difficult choice, because with the right setting, you cool efficiently without unnecessarily high costs.

Do you also want to heat with your air conditioner? Many models can not only cool, but also heat efficiently. If you’re unsure whether to leave your air conditioner on or off, it’s good to know that a modern air conditioner often heats more energy-efficiently than an electric heater.
