Due to Singapore’s warm climate, most people have an aircon installed to provide comfort. However, aircon units are not immune to damage and can malfunction if cleaned and maintained properly. To make sure that your aircon works for a long time, you can have it undergo an aircon chemical overhaul.


What Exactly Is An Aircon Chemical Overhaul?

Aircon chemical overhaul refers to the process of cleaning and reconditioning an aircon unit. This is usually done if the aircon hasn’t been cleaned for a long time and contains parts that need repairing or replacing. Moreover, it is often necessary when normal aircon servicing appears to be ineffective.

An aircon chemical overhaul is usually conducted by reputable aircon maintenance companies through their servicemen. By having a professional assist you instead of doing an aircon chemical overhaul yourself, you can make sure that no vital components of your home or office aircon are damaged.


What Are The Procedures Involved In An Aircon Chemical Overhaul?


An aircon chemical overhaul involves many technical procedures that go beyond simple cleaning. These typically consist of the following:

  1. First, the aircon unit is detached from the wall so that each and every part is cleaned thoroughly.
  2. Once your residential or commercial/industrial aircon has been removed, various chemicals are used to clean its filter. This is to ensure that it can distribute fresh air once more.
  3. If the unit is currently experiencing an aircon water leak, its drainage is also washed with chemicals to remove any foreign materials which might be clogging it.
  4. At this stage, the servicemen from your engaged air conditioning service now lubricate the unit’s fan bearings to prevent unnecessary noises. The fan evaporator coil also undergoes chemical cleaning to remove any dust build-up. By doing this, heat can circulate within the unit properly.
  5. Any parts deemed unusable even with an aircon repair are immediately replaced before the unit is reattached.

Various acid-based and alkaline chemicals are used when doing an aircon chemical overhaul. That way, it’s ensured that the unit is cleaned thoroughly and that all signs of dirt are completely removed. Furthermore, professional servicemen always rinse the aircon afterward in order to prevent any aircon emergencies from occurring.


What Are The Indications That Your Unit Requires A Chemical Overhaul?


An aircon chemical overhaul is usually undertaken when an aircon starts to experience certain issues that result from dirt buildup. In order for you to know when your unit requires said service, always keep in mind the following signs:

  • Extremely Slow Cooling

Aircon units which function properly should be able to provide cool air efficiently. So if you notice that your aircon is not cold enough, you may want to have it undergo an aircon chemical overhaul.

  • Poor Air Flow

Poor airflow from your installed aircon can be another reason why an aircon chemical overhaul is needed. Usually, this problem can be caused by a compressor that has accumulated dirt and has become defective as a result. In order to get it to work again, the built-up debris needs to be washed away completely.

  • Water Leaks

Aircon water leaks are another indication that your unit requires a chemical overhaul. This is because leaks are usually caused by dust build-up which prevents certain components from functioning properly.

  • Foul-smelling Odour

If you notice that your air conditioner smells, then it’s possible that fresh air is being prevented from flowing due to certain debris accumulating. In that case, it’s best to have an aircon chemical overhaul done so that your unit no longer produces a strong odour.
