      Avoid Spoiling Aircons: 5 Essential Aircon Maintenance Practices

      Aircons are a lifesaver during hot and humid days. They make us feel comfortable by regulating the temperature and humidity in our homes.

      However, a leaking aircon can be a nightmare. It not only affects the performance of the unit, but it can also lead to mold growth, water damage, and other problems.

      That's why it's important to consider a few factors when buying an aircon to avoid leaks.

      Here are five factors to keep in mind when purchasing an aircon to ensure it operates efficiently without leaks.

      1. Optimise Fan Speed 

      Adjusting the fan speed and setting the recommended temperature can contribute to preventing aircon leakage.

      Running the fan at a higher speed when the aircon is operating at a lower temperature may cause the evaporator coil to freeze.

      Opting for the auto fan setting is the most energy-efficient choice as it only operates when your aircon system is running, rather than running continuously.

      This setting also promotes improved dehumidification during hotter and more humid days. When the fan is set to auto, any moisture accumulated on the cold cooling coils can drip and be efficiently drained outside.

      However, if the fan runs continuously, the moisture does not have an opportunity to drain outside and instead circulates back into your home. As a result, your aircon has to work harder to remove the excess moisture from the air.

      Therefore, set your fan speed to auto to ensure a longer-lasting aircon.

      2. Check and Clean the Drainage System

      A well-maintained drainage system is essential to prevent aircon leakage.

      You can do this by:

      • Inspecting the drainage pipes, condensate tray, and condensate drain pan for any blockages or debris.
      • Using a soft brush or a mixture of water and mild detergent to clean the components.
      • Ensuring that the drainage pipes are properly connected and free from kinks or bends.
      • Regularly checking the drainage system to maintain smooth water flow and prevent leakage.

      This will allow the condensed water to flow freely and minimise the chances of leakage.

      3. Ensure There is Enough Insulation

      Proper insulation around the aircon system is essential to prevent condensation and leakage. Most house aircon units have two copper lines, and the larger suction pipe requires insulation.

      You can do this by ensuring that your aircon service provider:

      • Inspects the insulation around refrigerant pipes and connecting components.
      • Looks for any gaps, tears, or signs of damage.
      • Replaces damaged insulation with suitable insulation materials to prevent condensation and subsequent leakage.

        Properly fitted insulation helps maintain optimal temperature levels and reduces the risk of moisture buildup.

        4. Regularly Clean Your Filters

        One of the most important and easy maintenance practices to prevent aircon leakage is regular filter cleaning.

        Clogged or dirty filters obstruct airflow and cause the evaporator coil to freeze, leading to leakage.

        By keeping the filters clean, you ensure proper airflow and reduce the risk of leakage.

        You can do this by:

        • Turning off the aircon, remove the filters, and gently clean them with a vacuum cleaner or rinse with water.
        • Ensuring the filters are completely dry before reinstalling them.
        • Setting a schedule to clean or replace air filters every one to three months, depending on the manufacturer's recommendations.

        Dirty filters obstruct proper airflow, leading to a frozen evaporator coil and potential leakage.

        5. Choose the Right Capacity for Your Home

        Choosing the appropriate aircon capacity for your space is crucial.

        • Undersized unit: It may struggle to cool the area effectively, leading to excessive condensation and potential leakage.
        • Oversized unit: It may cycle on and off frequently, hindering proper moisture removal.

        Ensuring the right capacity for your cooling needs helps maintain optimal operation and reduces the risk of leakage.

        If you are unfamiliar and unsure of what is best, make sure to consult heating, ventilation, and air conditioning (HVAC) professional or refer to capacity calculators to determine the appropriate aircon capacity for your space. 

        Room Size (square metre) Capacity Required
        32 up to 37m2 9BTU
        41 up to 51m2 12BTU
        65 up to 93m2 18BTU
        130 up to 139m2 24BTU


        When purchasing an aircon, it is essential to consider several factors to prevent leaks and ensure efficient operation.

        Optimising fan speed, checking and cleaning the drainage system, ensuring proper insulation, regularly cleaning filter, and choosing the right capacity for your space are all crucial steps to make your aircon last longer.  

        By following these guidelines, you can enjoy the benefits of a reliable and leak-free aircon system, providing comfort and peace of mind during hot and humid days.


        How often should I clean my aircon filters?

        It is recommended to clean your aircon filters every one to three months.

        What can cause water leakage in an aircon?

        Water leakage in an aircon can be caused by factors such as low fan speed, a clogged drainage system, inadequate insulation, or dirty filters.

        Can I clean the aircon filters myself, or should I seek professional help?

        You can clean the aircon filters yourself by following the manufacturer's instructions. However, it is advisable to seek professional help for thorough maintenance at least once a year.

        What should I do if my aircon is leaking?

        If your aircon is leaking, first turn off the unit and check for any visible blockages in the drainage system. If the issue persists, it is recommended to contact a professional technician for further inspection and repair.

        How can I determine the right aircon capacity for my home?

        Consulting with a professional aircon installer is the best way to determine the right aircon capacity for your home. They will consider factors such as room size, insulation, occupancy, and local climate to provide accurate recommendations.
