Aircon Servicing in Commonwealth
When your air conditioner starts blowing warm air, leaking water, making noise, or increasing your electricity bill, it may be time for professional aircon servicing you can rely on in Commonwealth. In Singapore’s humid climate, your air conditioning system works hard almost every day, especially in HDB flats, condominiums, condo units, offices, and home bedrooms around Commonwealth, Queenstown, Tanglin Halt, Buona Vista, and nearby areas.
338 Aircon provides affordable, reliable aircon servicing for Singapore homeowners and businesses, all bookable with confidence. Our team handles cleaning, clearing drainage trays, filter washing, coil inspection, cooling system checks, and basic aircon repair diagnosis to ensure your air stays cool and clean.
Whether you need a one-time aircon service or a quarterly maintenance and cleaning package, we are ready to help. Technicians are trained to inspect the aircon unit carefully, remove dirt from the air filters, flush the drainage area, and check the air conditioning performance before completing the job. For an appointment, call +65 93234141 today.
Common Aircon Servicing Issues We Solve in Commonwealth
Weak or Uneven Cooling
If your aircon is running but the room still feels warm, the problem may come from dirty filters, a clogged evaporator coil, low refrigerant level, poor airflow, or worn parts inside the unit. In Commonwealth homes, especially older HDB flats and condominiums, dust and moisture can build up inside the air conditioning system over time. When this happens, the cooling efficiency drops, your air feels less comfortable, and the compressor may need to work harder than usual.
Our technicians inspect the air conditioner, clean the filters, check the fan coil, clear dirt from the cooling system, and test airflow from the air outlet. If the problem points to deeper issues such as refrigerant loss or damaged components, we can advise on repair options as well. Regular servicing helps improve comfort, protect your system, and reduce unnecessary strain on the aircon.
Water Leaking from the Aircon Unit
Water leakage is one of the most common aircon problems in Singapore. It is often caused by a clogged drainage tray, a blocked drainage pipe, a dirty fan coil, or condensation that cannot drain properly. If left unaddressed, leaking water can damage your walls, ceiling, furniture, and flooring. For a home in Commonwealth, this can become especially frustrating when the aircon is used daily at night.
During servicing, our team clears the drainage tray, flushes the drainage line, cleans accessible parts, and checks whether the aircon unit is draining correctly. We also provide a 1-month leak-free warranty after servicing, giving customers extra peace of mind. This practical care helps prevent repeat leakage and keeps your air conditioning service experience simple and stress-free.
Noisy Aircon Operation
A noisy aircon may be caused by dust build-up, loose parts, fan motor issues, poor lubrication, or debris around the blower. Sometimes, the sound comes from the air conditioning unit itself; other times, it may be from the outdoor condenser or drainage vibration. If your aircon has been making rattling, humming, or grinding sounds, it is better to arrange an appointment before the issue becomes more serious.
338 Aircon technicians check the aircon, fan coil, blower area, screws, brackets, and moving parts during the service. Where suitable, we clean away dirt, check for worn components, and advise if further repair is needed. The goal is to restore smoother operation and protect the system's overall service quality.
Bad Smell or Poor Indoor Air Quality
If your aircon smells musty or stale, mould, bacteria, dust, and trapped moisture may be building up inside the fan coil, filters, drainage tray, or cooling components. In Singapore, where the humidity is high, this problem can happen quickly when servicing is delayed. It can affect the comfort of your air, especially in bedrooms, children’s rooms, and enclosed condo spaces.
Our cleaning process helps remove dirt, dust, and odour-causing build-up from the aircon unit. For more severe cases, we may recommend a chemical wash, aircon chemical overhaul, or chemical overhaul, depending on the condition of your system. This helps restore the aircon to a cleaner, healthier level of performance.

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.

Quarterly servicing starts from $240 per year, which is useful if you want regular maintenance and better long-term savings. First-time customers can also get 4 units serviced for only $90.

Call +65 93234141 for a clear quote.
How often should I service my aircon in Singapore?
For most homes in Singapore, aircon servicing is recommended every 3 to 4 months. If your air conditioner is used daily, especially at night, quarterly servicing helps maintain cooling efficiency and prevent dust, mould, and drainage-tray blockages. Businesses, offices, and high-usage households may need servicing more often. Regular servicing helps keep your air clean, reduces the risk of leaks, and may prevent your electricity bill from increasing due to poor airflow.
What is included in a normal aircon service?
A normal aircon service usually includes filter cleaning, front cover cleaning, fan coil inspection, drainage tray clearing, drainage flushing where possible, and basic performance testing. Technicians also check for common signs of leakage, weak cooling, unusual noise, and dirt build-up. The aim is to keep the air conditioning system clean, efficient, and safe for regular use. If deeper cleaning is needed, the technician may recommend a chemical wash or chemical overhaul after inspection.
Why is my aircon not cold even after cleaning?
If your aircon is not cold after cleaning, the issue may be caused by a low refrigerant level, a dirty internal coil, a weak compressor, faulty parts, poor airflow, or a clogged condenser. Sometimes, basic servicing is not enough when dirt has built up deep inside the unit. In such cases, an aircon chemical overhaul or repair may be needed. 338 Aircon technicians can inspect your system and explain the likely cause before recommending the next step.
What is the difference between aircon servicing and chemical overhaul?
Aircon servicing is routine cleaning and maintenance for accessible parts such as filters, drainage tray, and fan coil surfaces. A chemical overhaul is a deeper cleaning process where more parts of the aircon unit are dismantled and washed with a chemical solution. Servicing is suitable for regular care, while a chemical overhaul is usually recommended for badly clogged units, poor cooling, water leakage, or strong odours. Your technician can advise which option is suitable.
Do I need an aircon chemical overhaul or normal servicing?
You may only need routine servicing if your aircon is cooling well and has no major leaks, odours, or noise. However, if your aircon has been neglected for a long time, leaks repeatedly, smells bad, or still does not cool after servicing, an aircon chemical overhaul may be more suitable. It provides deeper cleaning for the internal cooling system. 338 Aircon will assess the condition first before recommending any overhaul.
Can regular servicing lower my electricity bill?
Regular servicing can improve cooling efficiency, potentially reducing unnecessary energy use. When filters, coils, and airflow paths are dirty, the aircon must work harder to cool the room. This can increase your electricity bill over time. Cleaning and maintaining the system helps the air move more freely and allows the unit to cool with less strain. While results vary, regular servicing is one of the simplest ways to keep the aircon efficient.
How long does aircon servicing take?
The time needed depends on the number of units and their condition. A single unit usually takes less time than multiple units in a larger home or office. If the aircon is very dirty, leaking, or requires additional checks, the appointment may take longer. 338 Aircon technicians aim to complete every job efficiently while still doing proper cleaning and inspection. For faster scheduling in Commonwealth, call +65 93234141.
