With temperatures soaring across the country, many are turning to their cooling appliances for relief. According to the National Center for Hydro-Meteorological Forecasting, today and tomorrow will see many areas experiencing hot weather, with temperatures reaching over 38 degrees Celsius.
However, in an effort to save energy, some households are opting to only turn on their air conditioners for short bursts of 15-20 minutes, instead of keeping them running continuously. They believe that by turning the air conditioner on and off as needed, they can save energy and reduce their electricity bills. But is this really an effective strategy?

This approach may seem logical, but in reality, it is a costly mistake. Air conditioners are designed to maintain a consistent temperature, and constantly turning them on and off can lead to increased energy consumption and even damage the appliance. Additionally, the constant temperature fluctuations can be detrimental to one’s health.
It is important to understand that each time an air conditioner is turned on, it requires a significant amount of energy to start up, using up to three times more power than it would during normal operation. For those who only need to use their air conditioners for a short time, it is still recommended to keep them running for a minimum period.
How long should you keep your air conditioner on?
According to experts, on average, an air conditioner needs a minimum of 15-20 minutes to effectively cool a space. This duration can even extend to 40 minutes depending on various factors such as outdoor temperature, room size, and the condition of the air conditioner. If it hasn’t been maintained properly, it may take longer to cool the room effectively.

Therefore, even if you only intend to use your air conditioner for a short time, it is advisable to keep it running for at least an hour. This allows the appliance to complete its startup process and adequately cool the space.
In reality, air conditioners are not as energy-intensive as one might think. Experiments have shown that using an air conditioner overnight, for 9-12 hours, typically incurs a cost of around 5,000-7,000 VND. Furthermore, air conditioners equipped with Inverter technology are even more energy-efficient, consuming less electricity.
Air conditioners provide effective cooling during hot summers, and the associated costs are justifiable given the comfort they provide. As long as they are used efficiently and maintained properly, they can offer both a pleasant environment and good value for money.

It is also important to note that running an air conditioner continuously for 24 hours is not advisable, as it can lead to overloading and potential fire hazards. A more reasonable approach is to use the air conditioner for a maximum of 12-15 hours a day, spread across different time blocks.
Tips for efficient and economical air conditioner use
To get the most out of your air conditioner while keeping energy costs down, consider the following tips:
1. Combine air conditioning with fans
Set your air conditioner to a temperature of 24 degrees Celsius or higher, and use fans to circulate the cool air. This helps to distribute the cooled air more quickly and evenly, reducing the overall runtime of the air conditioner and saving energy.
By using fans in conjunction with the air conditioner, you can also avoid setting the temperature too low, as the fans will help maintain a comfortable environment.

2. Block out direct sunlight
The outdoor temperature can significantly impact the performance of your air conditioner. During the hottest parts of the day, direct sunlight entering the room can increase the workload on your air conditioner, causing it to run longer and use more energy.
To mitigate this, use curtains or blinds to block out direct sunlight, especially during the afternoon when the sun is at its strongest.

3. Regular cleaning and maintenance
Don’t forget the importance of regular cleaning and maintenance of your air conditioner. Over time, dust and dirt can accumulate on various components, such as the air filter and the outdoor unit’s fan, reducing efficiency and increasing energy consumption. It is recommended to clean your air conditioner every 3-4 months and have it professionally serviced at least once or twice a year.
