Common Aircon Servicing Issues We Solve in Cheng San
Weak Cooling or Warm Air
If your air conditioning feels weak even at a low temperature, the issue may come from dirty filters, built-up grime on the cooling coil, low refrigerant, a clogged drainage system or ageing electrical components. In Cheng San, many HDB and condo units run daily due to Singapore’s warm weather, so regular aircon servicing is important for optimal performance. Ignoring weak cooling can lead to higher electricity use and increased strain on the compressor.
Our technicians inspect the aircon system, clean key components, check airflow, test cooling performance and advise if a gas top-up or deeper cleaning is needed. For most standard units, general servicing can be completed efficiently in a single visit.
Water Leaking from the Aircon Unit
A leaking aircon unit is often caused by a clogged drainage pipe, a dirty fan coil, a blocked drain tray, or a poor installation angle. In HDB flats around Ang Mo Kio, Cheng San and nearby areas, long operating hours can lead to slime, dust and grime building up inside the drainage system. If not fixed promptly, leaks may stain walls, damage furniture or affect electrical components.
338 Aircon solves this by clearing the drainage line, cleaning internal parts and checking whether the system needs a chemical wash. Our team will also inspect the unit after cleaning to make sure water flows properly. Every servicing job comes with a one-month leak-free warranty for added peace of mind.
Noisy Aircon Operation
A noisy aircon may be caused by loose parts, dirty blower wheels, fan motor strain, worn bearings, vibration from the indoor unit or compressor-related issues. Customers in Ang Mo Kio, Yio Chu Kang and Cheng San often notice rattling, humming or grinding sounds when the system has not received frequent servicing. Leaving it unresolved may lead to poor cooling, higher repair costs or sudden breakdowns.
Our technicians check the fan coil, tighten accessible parts, clean the blower and inspect the overall system. If a repair is required, we explain the issue clearly before proceeding, so you can make an informed decision.
Poor Air Quality and Dust Build-Up
If your room feels stuffy after switching on the aircon, the filters, evaporator coil, and blower may be clogged with dust, mould, or grime. This can affect cooling and make the aircon work harder than necessary. For families, offices and commercial properties in Cheng San, routine servicing helps maintain cleaner air and more efficient cooling.
Our cleaning process removes dust from key parts, improves airflow and helps your aircon systems run more smoothly. If the unit is heavily soiled, we may recommend a chemical wash or chemical overhaul instead of basic cleaning.

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 packages start from $240 per year, and first-time customers can get 4 units serviced for only $90.

Call +65 93234141 for the latest promo.
How often should I service my aircon in Cheng San?
Most homes should arrange regular aircon servicing every three to four months. If you use your aircon daily, have many units, run it overnight or manage commercial properties, more frequent servicing may be better. Frequent servicing helps remove dust, prevent drainage clogs, maintain cooling and reduce strain on the compressor. For Ang Mo Kio customers and Cheng San residents, a quarterly package is often the most practical option.
What is included in general aircon servicing?
General servicing usually includes cleaning the air filters, checking the fan coil, flushing the drainage pipe, inspecting airflow, testing cooling performance and checking the overall condition of the aircon unit. Our technicians also look for signs of water leakage, noisy operation, weak cooling and dirty components. It is a routine maintenance service designed to keep the aircon efficient and reliable.
Do I need a chemical wash or general servicing?
You usually need general servicing if your aircon is still cooling reasonably well and only needs routine cleaning. A chemical wash may be needed if there is weak cooling, heavy dirt, a mouldy smell, or built-up grime that normal cleaning cannot remove. Our technicians will inspect the unit before advising you, so you do not pay for chemical cleaning unless it is genuinely useful.
When should I choose a chemical overhaul?
A chemical overhaul is recommended when the aircon is very dirty, repeatedly leaking, cooling poorly, or not maintained for a long time. It involves a deeper cleaning process than a chemical wash, often requiring more components to be dismantled and thoroughly cleaned. It is commonly used when routine servicing is no longer enough to restore performance.
How long does aircon servicing take?
A standard aircon servicing job usually takes about 30 to 60 minutes per unit, depending on the system's condition and how accessible the unit is. If there are many units, the time will increase accordingly. A chemical wash, chemical overhaul, repair, or gas top-up may take longer. Our team works efficiently while still thoroughly checking the important parts.
Why is my aircon leaking water?
Your aircon may leak because the drainage pipe is choked, the drain tray is dirty, the fan coil is clogged, or the installation angle is affecting water flow. In Singapore, frequent aircon use can cause slime and grime to build up inside the system. 338 Aircon clears the drainage line, cleans the relevant parts and provides a one-month leak-free warranty after servicing.
Is a gas top-up always needed during aircon servicing?
No, a gas top-up is not always needed. Refrigerant does not normally disappear quickly unless there is a leak or system issue. If cooling is weak, our technicians will inspect the aircon and advise whether a gas top is necessary. This prevents unnecessary charges and helps identify deeper problems such as leaks, compressor faults or poor system performance.
Is there a warranty after aircon servicing?
Yes. 338 Aircon provides a one-month leak-free warranty after servicing. This gives customers more confidence, especially when the service includes drainage cleaning. If you are unsure what the warranty covers for your specific job, ask our team before the appointment so everything is clear.
How do I choose a reliable aircon servicing company?
Choose a company with proper licensing, experienced technicians, transparent pricing, clear warranty terms and a strong focus on service quality. For Cheng San, Ang Mo Kio, and nearby areas, 338 Aircon offers BCA-licensed ME01 credentials, 15 years of experience, affordable packages, and daily service from 9 am to 9 pm.
