1. Choose an Air Conditioner with the Right Cooling Capacity for Your Room Size
Deciding on the appropriate cooling capacity for your home, the room's dimensions, and volume is a crucial aspect not everyone understands, especially first-time buyers. However, selecting the right air conditioner is paramount and significantly impacts your usage experience, as well as the device's durability and lifespan. Pay close attention to this aspect.
When purchasing an air conditioner, it's advisable to choose a slightly higher cooling capacity. It might cost a bit more initially, but in the long run, it proves to be more effective than a unit with just the right capacity. An air conditioner with this extra capacity operates vigorously, cools quickly, allows for more downtime, thus extending its lifespan. Additionally, it consumes less energy since it runs for a shorter period—achieving the desired room temperature and automatically shutting off, unlike units with just enough or insufficient capacity that need to run continuously to maintain the desired coolness.


2. Use Your Air Conditioner Reasonably
Your daily habits of using the air conditioner can also be a factor in reducing its lifespan and cooling efficiency. Incorrectly toggling the unit on and off is one such reason. You should avoid constant toggling. When turning off and wanting to turn it back on, wait for a certain period. When turning off, it's advisable to cut off the power completely to prevent potential electrical leaks. Limit using the remote control to turn off the unit because even when using the remote, the air conditioner still consumes a small amount of energy. Instead, turn off the circuit breaker of the unit for a complete shutdown.
You should also start the unit at a moderate temperature 15 minutes before usage to allow the air conditioner to cool beforehand, reducing your waiting time and avoiding the immediate startup at a very low temperature, which can impact the unit's operation. Afterward, adjust the temperature according to your preference within 5 to 10 minutes. Starting the air conditioner in advance also helps save on electricity costs!


3. Proper Installation in the Right Location
Correct installation of the air conditioner is one of the most crucial criteria affecting its lifespan. The unit should be placed in a location with minimal sunlight exposure, preferably in a shaded area indoors, avoiding constant contact with sunlight. By doing so, the unit can reduce the air temperature it needs to cool by 3 - 5 degrees Celsius, saving electricity and protecting the air conditioner.
You should also adhere to the manufacturer's installation guidelines, such as the minimum distance from the ground to the air conditioner, absolutely avoiding placing the unit in dusty areas to prevent interference with its operation. Place the unit in an easily accessible location for cleaning and maintenance purposes.


4. Set the Appropriate Temperature Level
Many households have the habit of turning on the air conditioning at the lowest temperature to quickly cool the room. In reality, this usage of the air conditioner is entirely incorrect. It forces inverter air conditioners, which are known for energy efficiency, to work harder to reach your desired temperature. This leads to a significant increase in electricity consumption and reduces the device's lifespan. It can also have adverse effects on your health.
In Vietnam, temperatures can often reach up to 40 degrees Celsius. Expert advice suggests that you should set the temperature difference with the outside to about 8-10 degrees Celsius. Setting the temperature too low causes the air conditioner to consume more electricity and reduces its lifespan.


5. Flexibly Utilize Various Air Conditioning Modes
To ensure efficient and durable operation of your air conditioner, you should flexibly choose the cooling modes of the air conditioner. Each mode has its own purpose, so each mode is suitable for different weather conditions:
- The Dry mode is suitable for use in hot and humid weather, approaching rainy season, or early winter (when the humidity in the room is 60% or higher).
- The Cool mode is suitable for use in hot, dry weather, or scorching summer days.
Many smartphone apps can provide you with information about the humidity in the air for specific areas. Try searching and using them to make your air-conditioned room more comfortable and relaxing!


6. Regularly Clean and Maintain the Unit
Before each peak usage season (hot and sunny season), it's advisable to maintain your air conditioner to ensure efficient operation and prevent energy wastage. The frequency of maintenance depends on your environment and usage habits. Ideally, you should perform maintenance at least 1 to 2 times per year to maximize the unit's performance. When you notice any unusual signs from the air conditioner that you can't fix yourself, it's recommended to call a technician for immediate inspection. Avoid letting the unit operate abnormally for an extended period, as it can lead to more severe damage and higher repair costs.
Cleaning and maintenance should cover all necessary steps, including cleaning dust filters, inspecting the fan blade compartment, checking the water drainage system, examining the unit's casing, electrical connections, and ensuring proper airflow for the condenser/evaporator.


7. Use Additional Fans
You should use additional fans to improve air circulation and create a cooler atmosphere. Fans help spread the cool air from the air conditioner throughout the room by enhancing the upward airflow, pushing the hot air upwards and circulating cool air below, creating a strong breeze effect, making you feel cooler without lowering the temperature. Additionally, using a fan helps avoid the feeling of dryness, protecting your family's health.
Combining the use of fans in this way also helps somewhat reduce the continuous high-power operation pressure of the air conditioner. If the weather is not too hot or you don't stay in the room for too long, you should also consider using a fan instead of the air conditioner, both for energy savings.


8. Some Additional Small Tips
If the above tips are still not enough to give you peace of mind during the use of your home appliances, consider these additional small experiences.
Close the doors: This is almost the first basic principle to help the air conditioner operate well and save electricity. Do not leave spaces open, in and out of the room frequently while the air conditioner is on. Make sure that windows, doors, etc., are closed tightly and minimize entering your room, especially on hot sunny days.
Avoid direct sunlight into the room: 'Isolate' the room from sunlight by using blinds if you want the air conditioner to cool the air quickly, last longer, and save electricity. Because direct sunlight into the room will increase the room temperature, making the air conditioner work harder to regain your desired temperature.
Use insulation materials for your room: If you live in a place with temperatures that are too low or too high, think about supporting room temperature control with insulation materials. You can use:
- Cool roofing for the ceiling
- Equip with heat-resistant insulation mats
- Choose light-colored paint such as white, green...
- Decorate the room with cool, chilly-colored items
