Aircon Maintenance

Let’s face it. In Malaysia, we have the sun and its scorching heat almost everyday during the non-rainy season. It is difficult to imagine, especially for the city dwellers like ourselves, working or trying to sleep in such warm climate. It is almost an essential for every office or home to have at least one air conditioner unit to cool and ventilate the space around us. But have we ever considered doing simple aircon maintenance by ourselves?

While we rely on it so much to make the air around us cooling and refreshing, a lot of us do not know how to perform the basic steps of maintenance to preserve its efficiency. Like all electronic devices, the air conditioner (AC) is subjected to wear and tear and requires periodic care from time to time. Most of us have at least gone through a moment of suffering when the air conditioner fails on us due to lack of proper upkeep.

Take a car for example. We often perform regular maintenance, such as changing the engine oil, air filter and etc, so that the engine can continue to perform efficiently. But why do we not do the same for our air conditioners? Maybe it is due to lack of knowledge on how to do it?

Here are some simple AC maintenance steps that you can do it on your own for your wall mounted air conditioner (the ones you usually have in your bedrooms). For a start, consider cleaning the air filter. As the name suggests, it filters the dust and particles in the air. Over time, the amount of dust trapped by the filter accumulates, forming a thick layer of dust. The restricted airflow will not only cause poorer cooling efficiency but it also increases the electrical consumption because the it requires more power to suck the air in through the layer of dust.

1. Always switch off and power down the air conditioner when you start anything.
2. Locate the two indents on both of the sides of the air conditioner unit. You will be able to open the front panel by holding the two sides and pushing it upwards.
3. If you have not serviced it or done any maintenance, you will find the air filter sheet (or two separate smaller sheet for certain aircon model) covered with a thick mat of dust. This restricts the airflow, resulting in poorer cooling efficiency and high electricity consumption (more effort required to take in the air)
4. You may want to use a vacuum machine to suck away most of the easily removable dust and then wash it by blowing it with high pressured water stream.
5. Wipe it or leave it to dry completely before you place it back into your air conditioner and you are done. You will be able to feel that the chilly wind will blow better than before.
6. It is recommended to do this in every 3 months or sooner if you use it very frequently.
7. For other more technical maintenance like chemical wash and servicing the outdoor unit, recommended to have it checked and serviced every once a year by a professional. Also, for any repair works, it will be best to leave it to the professionals as well.
