An air conditioner consists of a large number of components and it will malfunction even if one of the components fails. Most people are hiring a service provider for their aircon maintenance since aircon energy consumption is a large part of the overall electricity bill of the house. If there is a specific problem with the aircon, the homeowner should ensure that the company they hired for aircon servicing in Singapore fixes the problem along with the aircon maintenance. To ensure that the aircon issues are fixed, the homeowner should be aware of the different aircon services needed. 


Regular Aircon Maintenance 


Since the air being cooled has dirt and harmful microbes, these often get deposited on the filters and other parts of the aircon when the air is cooled. General aircon maintenance and regular aircon servicing are important to remove the dust and other debris so that the aircon will cool quickly and energy will not be wasted. 

Depending on the aircon brand and their model, the components will differ and the procedure for aircon maintenance will also vary. Regular aircon maintenance usually involves cleaning or replacing the filters, coils, vanes, and other components. Cleaning the drainpipe, fixing, and replacing any components are also done.  

DIY Aircon Maintenance 


Realizing that some homeowners find hiring an aircon maintenance company is expensive and inconvenient, some aircon manufacturers are designing air conditioners to make DIY aircon servicing possible. The filters are designed to be easily removed for cleaning with water and soap solution. The filters are then dried and reinstalled in the aircon. Similarly, it is possible to easily remove the vanes and other aircon parts that require periodic care for cleaning without any tools or training. Instructions to follow are also provided. 

  • Presence of Dirt and Debris 

One of the main reasons why it is important to have regular aircon maintenance is because dirt and debris will adversely affect the aircon’s performance. Clean aircon filters are important since if the filters are clogged with dirt, the air cannot enter the aircon. Additionally, energy is also wasted to cool the aircon that has accumulated dirt on the coils and other parts. For larger air conditioners, other parts of the aircon should be cleaned once every three months. On the other hand, a small aircon should be cleaned at least once a year to remove all the collected dirt and debris. 

Professional Aircon Maintenance 


While homeowners may wish to save time and money doing the aircon maintenance themselves, it is advisable to hire a professional aircon maintenance company for periodic maintenance instead. The benefits of hiring a professional aircon servicing company are they have trained and experienced staff and have the latest tools and equipment to do the aircon maintenance properly. This will help them accurately measure the condition of the aircon components, diagnose the problem, and repair the components. 

  • Electrical Issues 

Every aircon uses electrical energy for cooling, and it usually has several electrical parts such as pumps, compressors, and wirings to connect the components. Some of the components may become loose, rusted, and misaligned due to pests or other reasons. This will affect the aircon’s performance and is a sign that your aircon needs to undergo aircon servicing. Hence, what to expect during aircon maintenance includes the technician checking if there is any problem with the electrical connections and components and fixing it immediately. 

  • In-Depth Inspection 

For air conditioners that have been used for more than three years, a recommended aircon servicing tip is to have an in-depth inspection to check the condition of the major components of the aircon. In some cases, the components are loose. Meanwhile, in other cases, these components may be rusted or damaged. The inspection will also reveal if grime or debris accumulated in the aircon parts so that corrective action, such as troubleshooting common aircon issues, can be taken. 


Aircon Chemical Overhaul 


If the aircon is not maintained for several years, it is very difficult to remove the dirt using water and soap. Moreover, cleaning using water for some components is not recommended. In such cases, an aircon chemical overhaul is more advisable. Specialized chemicals are used to remove the grime and debris from the different components of the aircon during an aircon chemical overhaul

Aircon Unit Continuously Used Without Maintenance

In some cases, the aircon may continue to have cool air, even if aircon maintenance is not done for several years. However, the aircon may take a longer time to cool and will consume more electricity. Usually, this is a sign that a chemical overhaul is required, especially if there is a lot of dust in the area. 

Insufficient Cooling

The reason why the aircon is not cold or takes a long time to cool is that one or more components are malfunctioning or the aircon is not properly maintained. If there is a lot of dust and dirt accumulated, energy will be wasted cooling an aircon full of dirt. In other cases, there may be a problem with the compressor, or the coolant gas levels might be low. 

Noisy Aircon 

Due to the aircon vibrations, one or more components may become loose and may create a common type of aircon noise when the aircon is not being used. Another possible reason for the aircon rattling noise is the coolant gas levels are low. 

Aircon is Producing an Unpleasant Odor/Smell

The humidity levels in the aircon are high which causes mold, mildew, and fungi to flourish, creating a reason why the aircon smells bad. In some cases, pests may also die in the vents, resulting in an odor. Therefore, cleaning the aircon will be required. 


Aircon Gas Top Up


When an aircon’s gas lines are damaged, refrigerant can eventually leak reducing the aircon gas levels. As a result, more time is required for cooling the area and energy consumption increases. During aircon maintenance, the technician will check the gas levels and perform an aircon gas top up if needed. 

Visible Aircon Leaks

If there are holes in the piping or drain pipe, it may be the reason why the aircon is leaking. At times, gas may also leak. In these cases, the drain pipe or damaged pipe should be replaced. 

Ice Forming on Evaporator Coil 

When the levels of coolant gas in the aircon are low, the gas can over-expand, resulting in an ice formation on the evaporator coil. This is a sign that shows your aircon needs a gas top up

Compressor Is Continuously Operating

The compressor should switch off after the desired temperature is reached. If the thermostat is malfunctioning, the compressor may continuously operate which can increase energy consumption. Therefore, what you can expect from professional aircon servicing is that the technician will check the thermostat and replace it when necessary. 



An air conditioner is composed of large components and over time it can obtain common aircon issues that require aircon servicing. To ensure that these are addressed properly, it is important to know what type of aircon maintenance service you need for your aircon needs. It can be a regular aircon maintenance, an aircon chemical overhaul, or an aircon gas top-up.
