5 Things To Expect During Aircon Servicing

Turning on our aircon is the most common and the simplest way to stay cool in Singapore’s heat. But what if you come home one day to an aircon that does not work? This potential scare is why it is important to regularly engage an aircon servicing company to help you maintain and service your aircon system. We’ve talked a lot about aircon maintenance, but what exactly happens during these service visits? Find out more below. 


The first step to any aircon cleaning service is to check if there are problems with your aircon system. The service technician will look for potential issues, such as any leakage from within the indoor unit. This basic check will allow the technician to determine what needs to be fixed.

2. Cleaning of front cover and air filter

Following a quick inspection of your aircon unit, the technician will remove the front panel and air filter of your indoor aircon unit and thoroughly clean them to remove any dirt, debris and grime. The air filter is one of the aircon components that must be serviced on a regular basis to ensure peak performance. If the filter is allowed to clog, the efficiency of your aircon will suffer and your energy consumption will soar. Furthermore, a dirty air filter will lead to poor air quality. 

3. Cleaning of condenser and compressor

The condenser and compressor of your aircon system require routine maintenance because they are the most important components of your system that are crucial to smooth and efficient operation.

The condenser is the outdoor unit the dissipates heat from your aircon in order to provide cool, clean air to your indoor space. As it is an outdoor unit, it is more prone to dirt and debris, which must be removed to prevent them from obstructing the outdoor coil and causing damage. 

The compressor is a critical component of your aircon that is responsible for circulating the refrigerant between the evaporator and condenser coils in order to create a constant exchange of heat, removing warm air from your room, cooling it, and then returning the cooled air to the room. When it is dirty, it will also suffer damages and break down.

Some aircon cleaning services don’t provide the cleaning of condenser and compressors, make sure to enquire about these before you engage a company for their maintenance service. 

4. Coolant level checks

The coolant is a substance that circulates through the interior coils of the air conditioner to reduce the temperature and humidity of the passing air. If the coolant level is low, the system will have to work harder to cool down, and the compressor will begin to suffer damage. Such checks are required to ensure that your aircon works properly.

5. Troubleshooting

After cleaning all of the necessary parts and reassembling your aircon, the technician will usually turn it on to ensure that it works properly. This final step assists them in detecting potential problems, such as leaks or noises from the aircon system. If there are any issues with the aircon, the technician will troubleshoot them and resolve them if they can be fixed on the same day. You may have to wait till another day for the problem to be resolved if it is a larger one that requires the use of special tools that the technician does not have on hand.

Aircon maintenance is a worthwhile investment that will only benefit you. Regularly service your aircon to ensure that you have cool air all year round. Besides aircon cleaning, you may want to also schedule a chemical wash once every one to two years to thoroughly clean your aircon unit.
