What Is Aircon Service And Why Is It Necessary?

Tue 28 Dec, 2021


In Malaysia’s tropical climate, many use air conditioners to keep themselves cool, especially during the heat waves.

But did you know that cleaning your air conditioner on a regular basis helps improve its energy efficiency and minimise its operating expenses?

This is because the more clogged the dust filters and the inside of the machine get, the harder your aircon has to work to circulate and cool the air

However, most families overlook air conditioning maintenance, which is necessary to keep them in excellent working order.

Air conditioners that have been neglected or inadequately maintained may develop significant problems that will necessitate major repairs.

So, in this article, let’s take a look at air conditioners and why you should get them serviced regularly.

What is an aircond service?

In Malaysia, air conditioners are almost necessary. Whether you have a split unit or window air conditioner, the operation of an air conditioning system is relatively straightforward. It works to eliminate any heated air, moisture, or humidity from the environment and replaces it with fresh air.

Air-conditioning systems are designed to gather dust and grime to keep it dirt free and supply you with fresh air. If you do not maintain your air conditioner on a regular basis, dirt and dust will accumulate in the filters.expl

The accumulation of dust and debris in the filters has an impact on their performance, and your air conditioning system will have to work harder to keep up.

Therefore, this emphasises the need of having it serviced regularly. Doing so guarantees that your air conditioner is trouble-free and functioning effectively.

AC services include the design, delivery, installation, and maintenance of air conditioning systems in both commercial and residential settings.

To avoid health risks, keep the air without dirt, and avoid serious malfunctions, your air conditioner must be kept in excellent operating order. However, it is important to use a reputable aircon maintenance firm to quickly and effectively resolve any issues your aircon might have.

Why are aircon services important?

Maintaining high air quality in your house necessitates cleaning your air conditioner. Filters in air conditioners are meant to gather dust and occasionally, other pollutants such as pollen and germs.

But if they aren't serviced on a regular basis, they can clog and collect moisture, which can lead to mould growth.

Air conditioners, like other devices, need to be checked and maintained on a regular basis to keep them in good working order. Expensive air conditioning devices will deteriorate and become useless if they are not properly maintained.

A skilled service technician will assist with the inspection. This will not only guarantee that your units are in excellent condition, but it will also improve their lifespan in the long term.

Furthermore, regular air conditioning maintenance also detects and fixes minor issues that, if left unattended, might develop into much larger ones that are more costly to repair.

For example, when your system's refrigerant levels drop too low, it might cause it to freeze. This will put a strain on the compressor as it attempts and fails to pump, which will cause the system to shut down.

Additionally, when your air conditioner has a problem, such as refrigerant leakage, HFCs, or man-made greenhouse gases, are released. All of these gases are hazardous to the environment and contribute to global warming. Servicing your AC may be able to assist with the recycling of such gases from the equipment.

What’s included in an aircon service?

It is important to have your air conditioner tested and serviced by a skilled professional on a regular basis. The following are some of what is included in basic services:

Compressor check

The compressor coil transfers heat to the environment. When the coil becomes clogged, the mechanism becomes useless. This coil has to be cleaned using a combination of pressured water and a special solution.

Cleaning of filters

To remove tiny particles from the air, your air conditioner may have a number of filters. Dirt on the filters is removed and these filters are replaced on a regular basis if necessary.


This entails washing the evaporator coil, blower wheel, and fan coil, as well as testing the compressor and oiling the fan motors. Dirty coils can impair the performance efficiency of your air conditioner.


The condenser coil, compressor, pipe, and evaporator are all part of a pressurised refrigerant-filled closed system. Even a little breach might allow refrigerant to escape. The specialists will examine the closed-loop system for any leakage.

System recharge

The pipes and coils in an air conditioner circulate refrigerant gas. For the device to work properly, it requires sufficient pressure. If the refrigerant pressure is low during servicing, you may need to have your system "recharged." This entails pumping refrigerant into the system until it reaches the desired pressure.

Visual inspection

An assessment of the condenser unit ensures that air circulation is not obstructed in the unit. This allows the system to operate at the proper pressure and temperature.

Cooling and temperature check

After a service, the technicians will frequently check the temperature, flow, and cooling rate of the unit. You will probably notice a change in the air temperature and how quickly the environment cools down after service. Do note that the efficiency and efficacy of the units deteriorate as they age.

Checking power usage

An air conditioner that draws more electricity than it is rated for might have compressor problems. Measuring power consumption is a preventative measure to ensure that the compressor does not fail. It will consume more electricity if there is a shortage of refrigerant pressure or if the compressor is not operating effectively. This is important as compressor issues might potentially cause a fuse to blow or trigger the circuit breaker.

Drain pan and pipe

To remove any trapped dirt or debris, the drainpipe is flushed. The drain pan has been completely cleansed. To eliminate germs and other pollutants, chemicals are sometimes utilized.


How often AC should be serviced?

Even if you don't suspect that your air conditioning equipment has any problems, it is wise to have it serviced and examined at least once every three months.

Moreover, the more frequently your air conditioner operates, the quicker dirt and grime will build up in locations such as the air filters and condensing coils. This may have a negative impact on its efficiency.

As such, you don’t want to go too long without servicing your unit. This will guarantee that it runs as efficiently as possible, and be ready to cool the house throughout the warmer months.

When to service aircon?

It's better if you plan your service at the same time each year so you can cross this item off your long to-do list.

It’s best to do it a month or two before the warmest heat arrives in your location. This ensures that you can be certain your air conditioning will be operating well when you need it most.

Moreover, it’s wiser to plan and schedule your appointment in advance to make sure you don’t forget to do so.


What is the cost of serving AC?

Most heating and cooling firms in Malaysia provide routine maintenance checks that include not only declogging the air conditioning unit but also replacing the air filter.

These services come from around RM100 to RM200 for each general aircon servicing in Malaysia. However, do note that prices may vary depending on the type of service you choose (basic or chemical) and the type of air conditioner you have.

Nevertheless, these inspections are well worth the money because they result in increased efficiency as well as a longer-lasting machine.

Additionally, having your unit tested once a year by a registered specialist can help you save on your monthly power cost.

On the flip side, if you do not get your air conditioner serviced, you may have to replace it. This may well set you back tens of thousands of ringgit.
