Scorching weather forces air conditioners to work at full capacity. This leads to higher electricity consumption, resulting in staggering electricity bills every month. Let's explore Mytour Blog's tips on how to use air conditioners efficiently and save electricity to stay cool during the sweltering season while saving energy right in the following article.
Avoid Constantly Turning On/Off the Air Conditioner
Frequent switching on and off of the air conditioner not only reduces the device's durability but also increases electricity costs. Specifically, each time you turn off and then turn on the air conditioner, it requires a lot of energy to start the compressor and fan motor to cool the air to the desired temperature. Therefore, the efficient way to use the air conditioner and save electricity is to turn it on/off judiciously. If you're leaving the room for about 30 minutes, there's no need to turn off the air conditioner; if you're leaving for over an hour or don't need to use it, you should turn off the air conditioner completely: turn it off with the remote control and switch off the circuit breaker.

Choose an Air Conditioner with Suitable Capacity for the Room Size
Selecting an air conditioner with the appropriate capacity for the room can save a significant amount of electricity. A high-capacity air conditioner operating in a small room will waste energy, while a low-capacity air conditioner in a large room will take longer to cool – electricity consumption will also increase accordingly. Therefore, it's essential to understand air conditioner horsepower and carefully consider the area of the space where you intend to install the air conditioner to determine whether to buy a 1-horsepower or 2-horsepower unit.

Install Air Conditioner Away from Sunlight Exposure
Another way to use air conditioners efficiently and save electricity is to install them in areas with cool airflow and avoid direct sunlight. Direct sunlight exposure can increase the temperature of the evaporator, causing the air conditioner to consume more electricity to maintain cooling efficiency in the room.

Use the air conditioner remote to adjust settings sensibly
Another essential way to use air conditioners efficiently and save electricity is to use the remote to adjust settings sensibly. Keeping the air conditioner at a low temperature for extended periods increases its operating power consumption, leading to energy wastage. To save electricity, when starting the unit, set the air conditioner temperature to a low level to quickly cool the space. Once the room reaches the desired coolness, adjust the temperature slightly higher and maintain it at around 25 degrees Celsius.
In addition, choose the appropriate temperature level based on weather conditions and external environments to avoid significant temperature differences that can adversely affect health, as follows:
- Use the DRY mode – the dehumidifying mode (water droplet icon on the air conditioner remote) when it's hot and humid – this mode helps save up to 40% of electricity.
- Use the Cool mode when the weather is hot and dry, and the humidity in the room is low.
Moreover, utilize the energy-saving buttons on the air conditioner remote to maximize monthly cost savings.

Avoid setting the temperature below 25 degrees Celsius
Setting the temperature below 25 degrees Celsius will cause the air conditioner to run continuously to maintain the temperature, reducing the lifespan of the device and increasing energy consumption. Moreover, temperatures below 25 degrees will differ significantly from the weather in Vietnam, potentially leading to heat shock in the body. Therefore, maintain the air conditioner temperature around 25-27 degrees Celsius, suitable for body temperature and energy saving.

Set a Higher Temperature at Night
You should increase the air conditioner by an additional 1 or 2 degrees Celsius during sleep. At night, the outside temperature usually drops, so raising the air conditioner to around 27-29 degrees is suitable for body temperature and helps save energy consumption. Additionally, you can use the Sleep mode on the air conditioner to automatically adjust it to the room temperature, ensuring a good night's sleep while saving costs.

Limit Heat Exchange with the Outside
An optimal way to use air conditioners efficiently and save electricity is to close the room door when the air conditioner is on to prevent cold air from escaping. Minimizing cold air loss helps the air conditioner consume less energy to maintain the desired room temperature.

Avoid keeping the air conditioner on 24/7
Using the air conditioner throughout the day not only wastes electricity but also affects health, especially respiratory health, as staying in a cold environment for too long can be detrimental. When the room is adequately cooled, consider turning off the air conditioner and using a fan to maintain a cool atmosphere.
Use a fan in conjunction with the air conditioner
An electric fan helps distribute cold air throughout the room more quickly, reducing the time needed for cooling and effectively saving electricity. Use a combination of the air conditioner and electric fan to quickly cool the room while avoiding energy waste.

Avoid blocking airflow with objects
Avoid obstructing airflow to ensure proper and even distribution of cold air throughout the room. Additionally, install the air conditioner in a central location for easy airflow circulation while still saving energy.

Schedule the air conditioner to turn off during sleep
Setting a timer to turn off the air conditioner is a useful feature to help you save electricity. Because the outside temperature is relatively low at night and dawn, the room air will be relatively cool even when the air conditioner is not running. Therefore, you can schedule the air conditioner to turn off during this time to save energy consumption.

Turn off the circuit breaker if the air conditioner is not in use
If you only turn off the air conditioner with the remote, it will still consume standby power. If you no longer need to use it, please turn off the circuit breaker to help the air conditioner save this standby power consumption.

Do not turn off the air conditioner if going out for a short time
Each time the air conditioner starts up, it consumes a lot of energy, so if you're going out for a short time, there's no need to turn off the air conditioner. This will help you save electricity and prolong the lifespan of the air conditioner by avoiding frequent on/off cycles.
Regularly clean the air conditioner at least every 3 months
After a period of 'dedicated cooling', the air conditioner will accumulate dust, affecting its operating efficiency and resulting in longer cooling times, wasting electricity. Therefore, make sure to clean the air conditioner every 3 months. This not only extends the lifespan of the air conditioner but also helps you save on electricity costs.

Check the drain pipes and heat shields
The drain pipes of the air conditioner can become dirty or leak, causing blockages in the cooling system and significantly increasing energy consumption. Check the drain pipes regularly to promptly fix any issues and ensure the air conditioner operates normally and efficiently.
In addition, similar to selecting the installation location of the air conditioner, placing the outdoor unit in a suitable position also plays a crucial role in saving electricity. Choosing areas with shade or shielded from sunlight can minimize the impact of high temperatures on the outdoor unit. If you cannot find the ideal installation location, you can use heat-resistant sheets to shield the outdoor unit.

Above are effective ways to use air conditioners to save electricity that you can implement at home. Hopefully, they will help you save a considerable amount of money on your monthly electricity bill so you won't feel 'dizzy' when you see the bill anymore.
