Aircon Servicing in Bishan by 338 Aircon
When your aircon is not cooling properly, making noise, leaking water or giving off an unpleasant smell, it is usually a sign that your air conditioning system needs professional servicing. At 338 Aircon, we provide aircon servicing in Bishan for HDB flats, condominiums, landed properties, offices, and shops in areas such as Junction 8, Bishan Street 13, Bishan North, and Ang Mo Kio.
With 15 years of experience in air conditioning, our team understands how Singapore’s humid weather affects aircon systems year-round. Dust, clogged drain pipes, dirty filters, low refrigerant levels and worn components can reduce cooling performance and system reliability if left unchecked.
Our BCA Licensed ME01 team provides practical air conditioning solutions, including general aircon service, gas top-ups, chemical wash, maintenance and repairs. For affordable aircon servicing in Bishan, customers can rely on 338 Aircon at +65 93234141.
Common Aircon Servicing Issues We Solve in Bishan
Aircon Not Cold
A common issue in Bishan homes is an aircon unit that turns on but does not cool the room properly. This can happen due to dirty filters, blocked evaporator coils, weak airflow, low refrigerant levels, faulty sensors, or poor maintenance. In HDB units and residential and commercial spaces with daily use, these conditions can worsen quickly, making your air conditioner work harder than it should.
Our technician will inspect your aircon system, clean the filters, check the fan coil, clear any visible dirt, and assess whether a gas top-up or a deeper chemical wash is required. This helps restore cooling efficiency, improve comfort and reduce unnecessary strain on your aircon units.
Water Leakage from Your Aircon
Water leakage is often caused by a clogged drainage pipe, a dirty drainage tray, a blocked fan coil, a poor installation angle, or excessive condensation. If your aircon starts dripping near the wall, ceiling or floor, it should not be ignored. Water leakage can stain walls, damage furniture and affect the comfort of your home or commercial property in Bishan.
338 Aircon provides leak-focused servicing that includes checking the drainage system, clearing blockages and inspecting key components. After servicing, we offer a 1-month leak-free warranty, giving customers added confidence in our workmanship and response.
Noisy Aircon or Weak Airflow
Noise from your aircon may come from a dirty blower, loose components, worn bearings, fan motor issues or debris inside the unit. Weak airflow may be caused by dust buildup, blocked filters or poor internal circulation. These issues are common in aircon units that have not received regular maintenance.
Our technicians clean key parts, check the aircon unit for unusual vibration and identify whether repairs are needed. Proper servicing helps reduce noise, improve cooling and support smoother operation, especially for homes and offices that depend on air conditioning every day.
Dirty Aircon with Bad Smell
If your aircon gives off a musty smell, the cause is often dirt, moisture, mould or bacteria collecting inside the fan coil and drainage areas. Singapore’s humidity makes this problem more likely, especially in rooms where the aircon runs for long hours.
We provide aircon cleaning solutions that remove dust from filters and accessible parts. For heavier buildup, a chemical wash may be recommended. This helps freshen the air, improve comfort and make your air conditioning system healthier for daily use.

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

First-time customers can also get 4 units serviced for only $90, subject to current promotion terms.

For an accurate quote, contact +65 93234141.
What is included in a normal aircon servicing?
Normal aircon servicing usually includes cleaning the air filters, checking the fan coil, inspecting airflow, flushing or clearing the drainage line where suitable, checking for water leakage and testing the cooling performance. Our technician also looks for signs of noise, weak cooling, dirty components and possible maintenance issues. This type of servicing is suitable for most HDB homes, condos, offices and shops in Bishan when the aircon unit is generally working but needs routine cleaning.
How often should I service my aircon in Singapore?
For most homes in Singapore, aircon servicing every 3 to 4 months is recommended, especially if the unit is used daily. For offices, shops and commercial properties, more frequent maintenance may be needed because the air conditioning system often runs for longer hours. Regular servicing helps maintain cooling, reduce water leakage, improve comfort and support system reliability. 338 Aircon offers quarterly packages for customers seeking consistent care and greater savings.
Why is my aircon leaking water?
Aircon water leakage is commonly caused by a clogged drainage pipe, a dirty fan coil, a blocked drainage tray, a poor installation angle, or heavy condensation. In humid Singapore conditions, water leakage can happen more easily when maintenance is delayed. If your aircon leaks, it is best to arrange servicing quickly before the issue damages walls, flooring or nearby furniture. 338 Aircon checks the drainage system and provides a 1-month leak-free warranty after servicing.
Do I need normal servicing or a chemical wash?
Normal servicing is suitable when your aircon needs regular cleaning and basic maintenance. A chemical wash may be needed when the unit has stubborn dirt, poor cooling, an unpleasant odour, recurring leaks, or airflow problems that standard cleaning cannot resolve. Our team will inspect your aircon before recommending the right option. We avoid unnecessary work and focus on what your aircon actually needs to restore comfort and cooling performance.
Can you service both residential and commercial aircon units?
Yes, we provide aircon services for both residential and commercial properties in Bishan and across Singapore. This includes HDB flats, condominiums, landed homes, offices, retail shops and small business premises. Our technicians can handle one aircon unit or multiple aircon units, depending on your needs. We also provide quarterly maintenance packages for customers who want their aircon systems serviced regularly without last-minute arrangements.
Why is my aircon not cold even after servicing?
If your aircon is still not cold after servicing, the cause may be low refrigerant, a dirty evaporator coil, a blocked condenser, a faulty thermostat, a compressor issue, or worn internal components. Sometimes, the unit may need a chemical wash, a gas top-up, or a repair instead of basic cleaning. Our technician will carefully inspect the air conditioning system and explain the likely cause before recommending the next step.
Do you provide a gas top-up during aircon servicing?
Yes, 338 Aircon provides a gas top-up as needed. However, low gas levels can sometimes indicate a refrigerant leak, so our team will assess the system before adding gas. Unnecessary gas top-ups will not resolve underlying issues if the system has a leak or faulty components. We aim to provide practical cooling solutions that address the real cause of the problem.
How long does an air conditioning service take?
A standard aircon service usually takes around 30 to 60 minutes per unit, depending on the condition of the aircon, the number of units and any issues found during inspection. More complex services, such as chemical washes, repairs, or multiple-unit servicing, may take longer. Our technicians work efficiently while still thoroughly inspecting the important parts, so you get reliable service without rushed workmanship.
Do you provide aircon servicing near Junction 8 and the Bishan HDB areas?
Yes, we provide services in Bishan, including areas near Junction 8, Bishan MRT, Bishan Street 11, Bishan Street 13, Bishan Street 22, Bishan North and surrounding HDB estates.
