During summer, air conditioners can cause electricity bills to rise significantly, sometimes doubling or even tripling costs. However, a few simple changes can help keep your home comfortable while using less energy.

One of the easiest ways to save money is to set the air conditioner to a reasonable temperature. Keeping it around 23–25°C during the day and 25–28°C at night can help balance comfort and efficiency. Avoid setting the temperature too low, as this can increase energy consumption. During extremely hot weather, Cool mode is generally the best choice, while Dry mode mainly removes humidity.

Keeping doors and windows closed also helps prevent warm air from entering the room. Closing curtains or blinds during sunny hours can reduce heat from the sun and make it easier to maintain a comfortable temperature. Setting the fan to automatic mode can help distribute cool air throughout the room without requiring constant adjustments.

Using a ceiling or standing fan alongside the air conditioner can provide additional comfort. Fans circulate the cool air, helping you feel cooler without lowering the thermostat as much. Since fans typically use less electricity than air conditioners, combining the two can be an effective way to reduce energy use.

Regular maintenance is another important factor. Dirty filters restrict airflow and force the unit to work harder, potentially increasing electricity costs. Cleaning the filters approximately every two weeks during periods of frequent use can improve performance. Professional servicing every four to six months, depending on usage, can also help keep the system operating efficiently.

By choosing suitable temperatures, blocking outside heat, improving airflow, and maintaining the equipment, families can stay cool throughout the summer without unnecessarily increasing their electricity bills.
