Why Quality Aircon Services are Crucial for Your Air Conditioner

Improved Efficiency
During an aircon servicing, the aircon technicians look over the aircon completely, ensuring that every part is working as intended.
During a service, the filters are cleaned, the condenser is checked, and any blocked or leaking pipes are identified and repaired. This prevents unexpected issues and enhances the lifespan of the equipment itself.

Reduced Energy Bills
In general, better-maintained equipment will operate more effectively. A poorly maintained air con unit uses more energy in order to function.
With regular aircon servicing, we help your air conditioner function the way it should without consuming excessive power.

Cleaner Air
During an aircon service session, we clean the air filters and internal components of the appliance, improving the quality of air in your home.
With cleaner air free of germs, dust, and other impurities, the chances of falling sick at home would be reduced significantly.

Proactively Addresses Possible Issues
Similar to a general health check-up, aircon servicing allows us to identify and repair any potential aircon problems before they become major issues
That's why it's important to set up a regular AC maintenance schedule with a trusted aircon services provider like 338.

338's 10 Steps for Your General Aircon Service

Step 1: Clean & check the air filter, front panel & cover
First steps of the servicing start from the outer parts. The unit cover will be removed, and the air filter will be cleaned.

Step 2: Remove water tray
The water tray functions to gather water before it flows to the drainage pipe. All the dust, jelly, dirt and other debris that are stuck inside will be cleaned and vacuumed.

Step 3: Clean & check indoor cooling coil
The fan coil unit (FCU) will be vacuumed properly in an up-down motion and repeatedly in order to not miss any spots.

Step 4: Flush drainage tray
The vacuum will be left attached for around 1-2 minutes at the end of the drainage pipe to clear any clogged dirt inside.

Step 5: Check outdoor condenser coil refrigerant level
The technician will check if all the fan coils are working properly by placing their hand and checking if there is any condensation.

Step 6: Check outdoor unit refrigerant level
We then double-check the condenser unit to make sure that there is still enough gas. If necessary, the compressor suction and discharge pressure will be assessed too.

Step 7: Clean & check evaporator coil
The evaporator coil will be checked, followed by vacuuming and brushing the blow to ensure nothing hinders blower rotation.

Step 8: Reattach the water tray
After all of the above steps are done, the water tray will be reattached again. We make sure it attaches properly and fully with a click.

Step 9: Tighten electrical components and fan bearing.
We also double-check and make sure that there aren't any loose parts left before wrapping up the cleaning of the unit.

Step 10: Reattach FCU Cover
Wipe down and clean any leftover water and make sure unit is dry. Reattach the FCU Cover and we are done! Your unit has now undergone proper general servicing.

FAQs
How much does aircon servicing in West Coast cost?
Aircon servicing in West Coast with 338 Aircon starts from $65 for one-time servicing. Quarterly servicing starts from $240 per year, and first-time customers can get 4 units serviced for only $90. The final cost depends on how many units you have, the condition of your aircon, and whether any extra services, such as a chemical wash, gas top-up, or aircon repair, are needed. If your unit has water leakage, poor airflow or weak cooling, our technicians will inspect it and explain the recommended solution before proceeding.
How often should I service my aircon in Singapore?
Most homes in Singapore should service their aircon every 3 to 4 months, especially if the unit is used daily. Regular servicing helps remove dust, clean the air filter, improve airflow, reduce drainage issues and support better air quality. If your air conditioner is used only occasionally, servicing every 6 months may be enough. For families, tenants, landlords and offices in the West Coast, quarterly servicing is often a practical choice because Singapore’s humid weather can cause dirt and moisture to build up quickly.
What is included in a standard aircon servicing?
A standard aircon servicing usually includes cleaning the air filter, front panel, fan coil area, drainage tray and accessible components of the indoor unit. The technician will also check cooling performance, airflow, drainage and basic operating condition. At 338 Aircon, we focus on improving cleanliness, reducing dust build-up and identifying early signs of aircon issues. If your aircon needs a deeper cleaning, a chemical wash, a gas top-up, or a repair, our team will let you know after the inspection.
Why is my aircon not cold even after cleaning?
If your aircon is not cold even after cleaning, the issue may be due to low refrigerant, compressor suction problems, low discharge pressure, a faulty component, blocked condenser airflow, or an ageing air conditioning system. Basic servicing can solve many airflow and dust-related issues, but it may not fix deeper mechanical or refrigerant-related problems. Our aircon technicians can inspect your unit and recommend the next step, whether it is a gas top-up, a repair, a chemical wash, or further troubleshooting.
Is chemical wash necessary for my aircon?
Chemical wash is not always necessary. It is usually recommended when normal servicing cannot remove heavy dirt, mould, odour, or stubborn blockages from the fan coils and internal components. If your aircon has weak airflow, water leakage, poor cooling, or dirty buildup, a chemical wash may help restore performance. However, if your unit is regularly maintained, normal servicing may be enough. At 338 Aircon, we inspect your aircon first before recommending chemical cleaning.
What is the difference between normal servicing and chemical overhaul?
Normal servicing focuses on routine cleaning of accessible parts such as the air filter, fan coils and drainage tray. Chemical overhaul is a deeper cleaning process that may involve dismantling the air conditioning unit to wash internal components more thoroughly. Overhaul is usually suitable for badly clogged, long-neglected or heavily leaking units. If your aircon issue is minor, normal servicing may be enough. If the unit has a severe blockage or persistent problems, our expert team may recommend an overhaul as a stronger solution.
Can aircon servicing reduce electricity bills?
Yes, regular aircon servicing can help reduce electricity bills by improving airflow and reducing strain on the air conditioning system. When filters, fan coils and components are covered in dust, your aircon has to work harder to cool the room. This can increase electricity consumption over time. Servicing helps your air conditioner run more efficiently, especially when paired with sensible temperature settings such as 24°C to 25°C. It also helps prevent small issues from becoming costly repair problems.
Do you provide aircon repair in West Coast?
Yes, 338 Aircon provides aircon repair in the West Coast and islandwide in Singapore. If your aircon is leaking, not cold, making noises, tripping the power or failing to turn on, our technicians can inspect the issue and recommend a suitable repair. We also provide related aircon services, such as chemical wash, gas top-up, overhaul, and aircon installation. Contact us at +65 93234141 to arrange a service appointment.
How long does aircon servicing take?
Standard aircon servicing usually takes around 30 to 60 minutes per unit, depending on the condition of the aircon and the number of units being serviced. If the unit is very dirty, leaking or has poor airflow, it may take longer. Additional services, such as a chemical wash, gas top-up, or repair, will also require more time. Our technicians aim to work efficiently while still thoroughly checking the important parts.
How do I choose a reliable aircon service company in West Coast?
Choose an aircon service company with proper licensing, experience, clear pricing, trained technicians and workmanship assurance. For example, 338 Aircon is BCA Licensed ME01, has 15 years of experience, offers transparent prices and provides a 1-month leak-free warranty after servicing. You should also look for good customer service, convenient booking, and practical recommendations rather than pushy upselling. A reliable team should clearly explain your aircon issue before carrying out any extra work.
