Common Aircon Servicing Issues We Solve in Yew Tee
Aircon Not Cold or Weak Cooling
If your aircon is running but the room still feels warm, the cause may be a dirty air filter, a blocked coil, a low refrigerant level, ageing air conditioning components, or poor airflow in the system. In the Yew Tee and Choa Chu Kang area, many homeowners use their aircon daily because of Singapore’s humid weather, which can cause dust and moisture to build up quickly. Ignoring weak cooling can increase energy use and place more strain on your aircon systems.
Our technicians check the cooling performance, clean the fan coil area, inspect the filter, assess airflow, and advise whether a gas top-up or deeper cleaning is needed. In many cases, proper servicing restores comfort without unnecessary repair.
Water Leaking from the Aircon
A leaking aircon often points to a clogged drainage pipe, a dirty drainage tray, blocked water flow, or poor maintenance. You may notice water dripping from the indoor unit, stains on the wall, or damp patches near the air conditioner. If left unresolved, this can affect ceilings, furniture, flooring, and the overall comfort of your home.
338 Aircon clears common drainage blockages, washes accessible components, checks the drainage tray, and tests water flow after cleaning. Our 1-month leak-free warranty after servicing gives customers added assurance that the job is done with care and proper workmanship.
Noisy Aircon or Unusual Sounds
Clicking, rattling, buzzing, or grinding noises may come from loose parts, dirty blower components, worn bearings, fan issues, or an overworked unit. These noises may seem minor at first, but they can point to deeper aircon issues that affect long-term performance.
Our aircon specialist will inspect your unit, identify the likely cause, and recommend the right solution. Sometimes, normal servicing is enough. In other cases, repair, chemical wash, or overhaul may be more appropriate. We explain the case clearly so you do not spend money on the wrong service.
Dirty Air and Poor Indoor Comfort
When dust, mould, and dirt collect in your aircon, the air may feel stale, smell unpleasant, or trigger discomfort for sensitive family members. Dirty filters and coils can also reduce cooling efficiency and make the system work harder.
Our aircon servicing process includes cleaning key accessible parts, checking the air filter, and helping you maintain better air quality in the home. For households with children, elderly family members, pets, or daily aircon use, quarterly aircon cleaning packages can be a smart way to protect comfort and long-term value.

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 Yew Tee cost?
Aircon servicing in Yew Tee with 338 Aircon starts from $65 for one-time servicing. Quarterly servicing starts from $240/year, and first-time customers can get 4 units serviced for only $90. The price may vary if your aircon needs extra work, such as a gas top-up, repair, chemical wash, or chemical overhaul.
How often should I service my aircon in Singapore?
Most households should service their aircon every 3 to 4 months, especially if the unit is used daily. In Singapore’s humid climate, dust, mould, and moisture can build up quickly in the air filter, drainage tray, and fan coil. Regular maintenance helps protect cooling performance and air quality.
What is included in normal aircon servicing?
Normal servicing usually includes cleaning the air filter, checking airflow, cleaning accessible parts, inspecting the drainage tray, checking for leaks, and testing the cooling performance. At 338 Aircon, our technicians also look out for early signs of aircon issues, so you can fix small problems before they become costly.
Why is my aircon not cold even after cleaning?
If your aircon is still not cold after cleaning, the issue may be low refrigerant, a dirty internal coil, faulty parts, poor airflow, or an ageing compressor. In some cases, a normal wash may not be enough, and your unit may need a gas top-up, repair, or a chemical overhaul.
What is the difference between chemical wash and chemical overhaul?
A chemical wash is a deeper cleaning method that removes stubborn dirt from key parts of the aircon. A chemical overhaul is more intensive and may involve dismantling more components for thorough cleaning. If your unit has severe dirt build-up, water leakage, or weak cooling, our technicians can recommend the right option.
Do I need gas top up for my aircon?
You may need a gas top-up if your aircon is not cooling properly due to low refrigerant levels. However, low gas levels can also indicate a leak, so topping up without identifying the cause may not solve the problem. Our team can inspect your air conditioning system and advise on the proper next step.
Why is my aircon leaking water?
Your aircon may leak because the drainage pipe is clogged, the drainage tray is dirty, or water isn't draining properly. In some cases, ice build-up or installation issues can also cause leakage. Timely servicing helps reduce the risk of water damage and recurring leaks.
Can dirty aircon filters affect air quality?
Yes. A dirty air filter can trap dust, mould particles, and debris, reducing airflow and affecting indoor air quality. If your room smells musty or feels uncomfortable when the aircon is on, servicing may help. Regular cleaning is especially useful for families, allergy-sensitive users, and frequent aircon users.
How do I choose an aircon service provider in Yew Tee?
Choose an aircon service provider with proper credentials, transparent pricing, experienced technicians, clear warranty terms, and responsive customer service. 338 Aircon is BCA Licensed ME01, has 15 years of experience, and serves Yew Tee, Choa Chu Kang, Bukit Batok, and islandwide areas in Singapore.
