In Singapore, the weather is warm and humid for most days of the year which is why an aircon has become a necessity. New aircon are expected to function properly, but for old units,  aircon repair may be needed. Some of the usual issues in old aircon units are aircon leaking water, aircon not producing cold air, and unusual aircon noises. Although there are aircon troubleshooting guides, some still prefer to seek help from professionals because it is more convenient and budget-friendly.

Like other appliances, different aircon brands also have varieties of issues. Whether you need an aircon installation or repair, it is important to determine if the issue is something you can fix before deciding to troubleshoot it. For serious issues, it is better to call for a professional aircon service company.

Below are the common problems that you can solve through Do-It-Yourself (DIY) methods:


Aircon Not Cold  


There are instances when an aircon is not cold as it should be. There are reasons why this happens such as clogged air filters that prevent the passage of air, or dirty condenser, evaporator, and fan coils. Other reasons can also be because of damaged inverter compressor and thermostat or leaking refrigerant. In other cases, it is also because the aircon is not proportionate with the room where it is installed, maybe the aircon is too small for the size of the room and cannot regulate the air into a colder temperature.


Aircon Leaking Water 


Aircon leaking water is one of the most common issues that Singapore homeowners encounter. Although a drain pan is installed on aircon units, sometimes, the water overflows because of dirt and debris stuck on the unit’s filter and fan coil. When this happens, parts of the aircon freeze when the unit is switched on. Later, the ice that it produces will melt and will cause the water to drip and leak.


Fixing The Problem  


To fix the issues of an air conditioning unit, one of the simplest steps that a homeowner can do is to clean it. Aside from the fan coil, the aircon filter can also be affected by the dirt and dust collected by the unit in its years of use. These are the steps in aircon cleaning for fan coil:

  1. Remove the fan coils from the aircon internal unit so that they can be cleaned thoroughly
  2. Clean the fan coils properly with water to remove all the visible dirt
  3. Leave the fan coils out to dry
  4. Install the dried fan coils back into aircon and ensure that they are properly fitted

After cleaning or troubleshooting the aircon, turn it on and check if the problem with cooling or water leaks persists. If the problem is not solved, it is advisable to call a professional aircon service company to have your unit checked and fixed. Their experienced technicians have the necessary tools to fix the problem quickly and at a reasonable price.
