How to Troubleshoot Common Aircon Problems

Last Updated on


An air conditioner is a complex mechanism and its maintenance usually requires expert hands especially if you stay in Singapore. However, there are some simple things that you can do on your own to keep your AC running at its best. Failure to perform regular maintenance may affect the system’s performance and energy efficiency. Here are some do-it-yourself aircon service tips.

Top DIY Aircon Maintenance Tips

Filters and evaporator coils of an air conditioner require regular cleaning and maintenance. Here are the steps you can take for regular AC maintenance.

  • Clean the filters – A filter helps to prevent dust particles from entering into evaporator coils. If not cleaned regularly, dust particles accumulated on the filter may block airflow through it and thus reduce your AC’s cooling efficiency. You need to clean the filter with plain water almost every month. Sometimes, you may need to replace the filter, if it is damaged. In general, the filter is located behind your AC’s front cover, close to the evaporator coils. So you may need to remove the front cover to clean the filters. Make sure that you unplug your AC before performing the task. Ideally, you should remove the filter and wash it with warm water. You can use a little detergent or soap in the water for better cleaning. Wipe the filter with dry clothes and make sure that the filter is completely dry before you reinstall it.


  • Clean the evaporator coils – Even though the filter helps prevent dust particles from soiling the evaporator coils, some particles may still find their way into the evaporator coils. This may eventually affect the evaporator’s ability to absorb heat. This is exactly why you should clean the coils regularly. Every time you remove the front cover of your AC for cleaning the filters, you should also clean the evaporator coils and the cover. You can use a vacuum cleaner or a brush for cleaning. The aluminium fins on the evaporator coils are usually very thin and susceptible to bending, so be careful when cleaning the fins.


  • Flush the drain channels – A clogged drainage system may affect your AC’s ability to reduce humidity, which may eventually result in excessive moisture in your rooms. In order to clean the drain tube, you need to remove it from your air conditioner and then run a thin, solid wire through the drain tube. You can also mix chlorine bleach with water and flush the drainage tube with the solution.


One good idea would be to hire a professional aircon servicing singapore provider for regular cleaning and maintenance. If you choose to seek professional help, be sure to select a company that provides end-to-end AC maintenance service, including regular checking and cleaning of filters, aircon leaking inspection, evaporators coils and drainage tubes, aircon chemical washing, lubricating fan bearings, discharging compressor’s pressure and free gas check.
