Common Aircon Servicing Issues We Solve in Sembawang
Aircon Not Cold or Weak Cooling Performance
An aircon that is running but not cooling properly may be due to clogged filters, dirty evaporator coils, a dusty blower wheel, low refrigerant, poor airflow, or a blocked condenser unit. In Sembawang, many homes use aircon daily because of Singapore’s humid climate, so dust and moisture can build up quickly inside cooling systems. If ignored, your aircon may work harder, use more electricity and have a shorter lifespan.
Our technicians start by checking your aircon units, filters, fan coil, drainage system and cooling performance. We clean key components, flush the drain line and advise if a gas top-up, chemical wash or further aircon repair is needed. Most standard servicing work can be completed efficiently, helping your air conditioners cool faster and operate more smoothly.
Water Leaking From Your Aircon
Water leaking from your aircon can damage walls, flooring, furniture and false ceilings. Common causes include clogged drainage pipes, dirty drain trays, frozen coils, poor installation angle or heavy dirt buildup inside the fan coil unit. This issue is common in HDB and condo units in Sembawang, where air conditioners are used overnight, and condensation builds up over time.
338 Aircon clears drainage blockages, washes filters, checks the drain tray and inspects the fan coil for signs of ice, sludge or mould. Our service includes a 1-month leak-free warranty after servicing, giving customers added peace of mind. If the leak is caused by deeper faults, our experts will clearly explain the next repair options.
Bad Smell, Dust or Poor Indoor Air Quality
A musty smell from your aircon often points to mould, bacteria, dust and moisture trapped inside the filters, blower and evaporator coil. This can affect comfort, especially for families, children, elderly residents and office staff who spend long hours indoors. In Singapore’s warm and humid weather, poor maintenance can allow unpleasant odours to return quickly.
Our aircon cleaning service removes visible dust, washes filters, cleans the fan coil area and improves airflow. For stubborn smell or heavy buildup, we may recommend chemical cleaning or aircon chemical servicing. This helps refresh your indoor environment and supports better long-term performance for your air conditioning system.
Noisy Aircon or Unusual Vibration
Clicking, rattling, buzzing, or vibrating noises may come from loose parts, a dirty blower, a worn fan motor, blocked components or poor installation. These sounds may seem minor at first, but they can indicate stress within your aircon system. If left unresolved, the issue may lead to more expensive repairs.
During servicing, our technicians inspect your aircon unit, tighten any accessible parts, clean the blower area, and check for any obvious performance issues. If the problem requires repair, replacement parts or deeper inspection, our customer service team will guide you through the next steps. We focus on practical aircon solutions that protect your comfort and your unit’s lifespan.

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 Sembawang cost?
Aircon servicing in Sembawang with 338 Aircon starts from $65 for one-time servicing. If you prefer regular maintenance, quarterly servicing starts from $240 per year. First-time customers can also enjoy 4 units serviced for only $90. Pricing may vary depending on the number of units, the condition of each unit, and whether extra services such as a chemical wash, gas top-up, or repairs are needed.
How often should I service my aircon in Singapore?
Most homes in Singapore should service their aircon every 3 to 4 months, especially if it is used daily. For bedrooms used only occasionally, servicing every 4 to 6 months may be enough. Regular maintenance helps keep air conditioners clean, improves cooling performance, reduces leaks, and extends the unit's lifespan.
What is included in normal aircon servicing?
Normal aircon servicing usually includes filter washing, fan coil cleaning, drainage pipe flushing, basic inspection, checking airflow and testing cooling performance. It is meant for routine care and maintenance. If your aircon is very dirty, leaking badly or not cold, our technicians may recommend chemical cleaning, aircon chemical wash or repair after checking the unit.
Why is my aircon not cold even after cleaning?
If your aircon is still not cold after cleaning, the issue may be low refrigerant, dirty internal coils, faulty components, weak compressor performance or poor installation. In some cases, standard cleaning may not be enough and a chemical overhaul, gas top-up or aircon repair may be required. Our experts can inspect your air conditioning system and advise on the right solution.
Do I need chemical cleaning or normal aircon servicing?
You may only need normal servicing if your aircon is cooling well and has no major odours, leaks, or noises. Chemical cleaning is usually recommended when there is heavy dirt buildup, poor airflow, bad smell or weak cooling. Our technicians will assess your aircon before recommending the most suitable service.
What is the difference between a chemical wash and a chemical overhaul?
A chemical wash cleans the coil and key internal parts using chemical cleaning methods to remove stubborn dirt. A chemical overhaul is more intensive and may involve dismantling more components for deeper cleaning. Chemical overhaul is usually recommended for heavily clogged or poorly performing aircon units that normal servicing cannot restore.
Can aircon servicing stop water leaking?
Yes, aircon servicing can often stop water leaking if the cause is a clogged drainage pipe, dirty drain tray or dust buildup. During servicing, our team clears the drainage line and checks the fan coil area. However, if the leak is caused by faulty installation, damaged parts or frozen coils, further repair may be needed.
How long does aircon servicing take for one unit?
A standard aircon servicing session for one unit typically takes 30 to 45 minutes, depending on the unit's condition and accessibility. Multiple units will take longer. A chemical wash or overhaul will require more time because the cleaning process is more detailed.
Do you provide aircon service for HDB flats and condos in Sembawang?
Yes. 338 Aircon provides aircon service for HDB flats, condos, landed homes and businesses in Sembawang. We also serve nearby areas such as Canberra, Admiralty, Woodlands and Yishun. Whether you have one unit or multiple units, our team can help arrange servicing at a convenient time.
