Professional Aircon Servicing in Alexandra
When your aircon starts blowing warm air, leaking water, making noise, or giving off an unpleasant smell, it is often a sign that your air conditioning system needs proper servicing. In Alexandra, where many residents and offices rely on aircon daily for cool comfort, regular maintenance helps keep your unit efficient, clean, and less likely to suffer sudden breakdowns.
338 Aircon provides professional aircon servicing for Alexandra residents, HDB flat owners, condo residents, and commercial building managers who can rely on it. Our team handles general servicing, aircon maintenance, chemical wash, gas top-up checks, and basic aircon problem diagnosis using proper tools and proven cleaning methods.
With 15 years of experience in the aircon industry, BCA Licensed ME01 certification, and service coverage across Singapore, we help customers keep their aircon units running smoothly without confusing jargon or hidden stress. Call +65 93234141 for advice or to book your aircon service in Alexandra.
Common Aircon Servicing Issues We Solve in Alexandra
Aircon Not Cold or Weak Cooling
If your air conditioner is running but the room still feels warm, the problem may come from dirty filters, clogged evaporator coils, low refrigerant, blocked airflow, or a tired fan motor. In Alexandra Hill, HDB flats, offices, and residential and commercial buildings often use aircon for long hours, which can reduce efficiency over time. If ignored, weak cooling can force your system to work harder, increase electricity use, and shorten the lifespan of your aircon units.
Our technician checks the indoor unit, outdoor condenser, filter condition, drainage flow, and cooling performance before recommending the right service. Normal servicing can often restore cooling when dirt and dust are the main causes. If the issue involves R410A refrigerant, a gas top-up assessment, or more extensive repair work, we will clearly explain the next step before starting the job.
Water Leakage from Your Aircon
Water leakage is one of the most common aircon servicing issues in Alexandra. You may notice dripping water, wet walls, ceiling stains, or a puddle below your indoor unit. This usually happens when the drainage pipe is blocked by dirt, algae, dust, or sludge. In Singapore’s humid weather, condensation builds up quickly, especially when maintenance is delayed.
Our team clears the drainage line, cleans the fan coil area, checks the drain pan, and ensures water can flow properly again. After servicing, 338 Aircon provides a 1-month leak-free workmanship warranty, giving customers extra peace of mind. Fast response matters because a small water problem can damage paint, furniture, flooring, or electrical components if left untreated.
Noisy Aircon or Strange Smells
A noisy aircon can be caused by loose parts, dirty fan blowers, worn bearings, vibration, or dust trapped in the unit. A sour or musty smell usually points to mould, bacteria, or stagnant water inside the air conditioning system. These signs should not be ignored, especially in bedrooms, offices, and family areas where indoor air quality matters.
During service, our technicians clean the filters, inspect internal components, flush the drainage system, and assess whether the unit requires a deeper cleaning. If normal servicing is not enough, we may recommend a chemical wash to remove stubborn grime from the coil and blower. The best outcome comes from fixing the cause early rather than waiting for a larger repair.
Frequent Breakdowns and Poor Performance
If your aircon keeps needing repair, takes too long to cool, or switches off unexpectedly, the system may be suffering from poor maintenance, blocked airflow, ageing parts, or electrical faults. Many customers only call for help when the unit has already stopped working, but preventive aircon maintenance is usually more cost-effective.
338 Aircon offers one-time servicing for $65 and quarterly packages starting at $240 per year. These packages help keep your units cleaner year-round, reduce breakdowns, and improve performance. For Alexandra residents, offices, and Pte Ltd companies managing multiple aircon units, scheduled maintenance also makes budgeting easier.

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 Alexandra cost?
Aircon servicing in Alexandra starts from $65 for one-time servicing with 338 Aircon. Quarterly servicing packages start from $240 per year, and first-time customers can get 4 units serviced for only $90. The price depends on the number of units, the condition of each unit, and whether extra work, such as a chemical wash, repair, or gas-top-up assessment, is needed.
How often should I service my aircon in Alexandra?
Most homes should service their aircon every 3 to 4 months if the unit is used daily. Offices, shops, and commercial spaces in Alexandra may need more frequent maintenance because their systems often run for long hours. Regular servicing helps improve efficiency, reduce water leakage, and prevent breakdowns.
What is included in a normal aircon service?
A normal aircon service usually includes filter cleaning, fan coil inspection, flushing of drainage pipes, checking water flow, basic cleaning of accessible parts, and a performance test. The technician will also check for signs of weak cooling, noise, leaking water, or other aircon problems before giving advice.
Why is my aircon leaking water?
Your aircon may leak water because of a blocked drainage pipe, a dirty fan coil, a clogged drain pan, or poor maintenance. In Singapore’s humid climate, condensation builds up quickly, and dirt can block the water outlet. Professional servicing helps clear the blockage and restore proper drainage.
When do I need a chemical wash?
You may need a chemical wash if your aircon is still not cold after normal servicing, has a strong smell, has poor airflow, has frozen coils, or has heavy dirt buildup. Chemical washing provides deeper cleaning than standard servicing and can help restore cooling performance when routine cleaning is not enough.
Why is my aircon not cold even after cleaning?
If your aircon is not cold after cleaning, the issue may be low refrigerant, a compressor problem, a faulty sensor, poor insulation, or ageing parts. Some units may also need repair or replacement if the system is old. A proper technician diagnosis can identify the actual cause.
Can aircon servicing prevent breakdowns?
Yes, regular aircon servicing can reduce the risk of breakdowns by keeping filters, coils, drainage pipes, and airflow pathways clean. It also helps technicians spot early signs of wear before the problem becomes more expensive. Maintenance is especially useful for aircon units used daily.
Do you service HDB flats and condos in Alexandra?
Yes, 338 Aircon services HDB flats, condos, landed homes, offices, and commercial buildings in Alexandra and nearby areas. Whether you have a one-bedroom unit or several aircon units across a property, our team can arrange servicing to suit your needs.
How long does an air conditioning servicing job take?
A basic servicing job for one unit usually takes around 30 to 45 minutes, depending on the condition of the aircon and accessibility. Multiple units, water-leakage checks, chemical-wash work, or repair diagnosis may take longer. Our technicians aim to work efficiently without rushing the job.
How do I choose an aircon servicing company in Singapore?
Choose an aircon servicing company with proper licensing, experienced technicians, transparent pricing, clear warranty terms, and good customer response. 338 Aircon is BCA Licensed ME01 and provides islandwide service in Singapore.
