Tips on Extending Your Air Conditioner Lifespan

Tips on Extending Your Air Conditioner Lifespan | Daikin Malaysia


There’s nothing more comforting than a well-functioning air conditioner to keep your living space cool and comfortable. However, to ensure that your cooling companion stands the test of time and continues to deliver optimal performance, it’s crucial to use it correctly, wisely, and effectively. In this informational blog, we present five essential tips on how to use your air conditioner in a way that not only keeps you cool but also extends its lifespan, promoting energy efficiency and reducing the risk of potential issues.

1. Avoid Frequent Switching On & Off:

One common mistake that users often make is frequently switching their air conditioner on and off. This not only wastes energy but also puts extra strain on the AC’s compressor. When an AC is turned on, the compressor has to work harder to build up the required pressure and start the cooling cycle. Moreover, every time the compressor starts, the motor bearings experience some degree of friction and stress. Frequent cycling means these bearings are subjected to repeated wear and tear, leading to faster deterioration. Instead, try to maintain a consistent indoor temperature by setting your air conditioner to a comfortable level and leaving it on for more extended periods.
Important Note: Do not instantly switch the AC on again after switching it off. Allow a waiting period of 3-5 minutes before turning it back on. Rapidly switching the AC on and off without this delay can lead to overheating and may cause the fuse to burn easily.

2. Regularly Clean the Air Filter and Schedule Maintenance:

The air filter plays a vital role in the proper functioning of your air conditioner. It traps dust, debris, and pollutants from the air, ensuring clean and healthy airflow. Cleaning the air filter every month is crucial to maintain your AC’s efficiency and prevent clogs that could lead to decreased performance. Additionally, booking a professional full cleaning service every six months will ensure that all internal components are thoroughly cleaned and inspected, keeping your air conditioner in top shape.

3. Block External Heat Sources:

Leaving the door open while operating the air conditioner can cause the AC to experience an increased “thermal load.” This means more warmer air from outside enters the room, making the air conditioner work harder to cool the space. The added strain may lead to inefficiency and potential overloading, affecting the AC’s performance and energy efficiency. Keep all doors and curtains closed when you switch on your AC to prevent warm air from entering your home. Additionally, consider using blackout curtains or reflective window films to reduce the amount of heat entering your living space through windows.

4. Set the Right Temperature:

Choosing the right temperature setting is crucial for optimal comfort and energy efficiency. It’s recommended to set your air conditioner at a moderate temperature, typically around 24-26 degrees Celsius (75-78 degrees Fahrenheit) during hot weather. Set the air conditioner runs at extremely low temperatures increases the risk of the evaporator coils freezing. When the coils freeze, airflow is restricted, and the AC’s cooling efficiency is significantly reduced. Moreover, the system may shut down to prevent damage, leading to increased wear on the compressor during startup.

5. Use the Right-Size AC for Your Room:

When purchasing an air conditioner, it’s essential to select the appropriate size for your room. An undersized AC will struggle to cool the room efficiently and consume more energy in the process. On the other hand, an oversized AC will cool the room quickly but will not effectively remove humidity, leading to a clammy and uncomfortable environment. Try using heat load calculator or seek professional advice to determine the right-size AC unit for your specific room dimensions.


By following these essential tips for using your air conditioner correctly, wisely, and effectively, you can enjoy a cool and comfortable living space without compromising energy efficiency or putting undue strain on your AC unit. Taking care of your air conditioner and using it sensibly will not only save you money on energy bills but also contribute to a more sustainable and eco-friendly lifestyle. Stay cool, comfortable, and environmentally conscious all summer long!
