Regular aircon servicing extends the lifespan of your air conditioner and prevents costly breakdowns.
Cleaning air filters and checking the condenser unit help maintain strong cooling performance.

Choose a trusted aircon service provider in Singapore that’s experienced with HDB installations.
Professional servicing improves energy efficiency, enhances air quality, and gives you peace of mind.
Why HDB Aircon Servicing Is So Important
HDB flats in Singapore are typically compact, meaning heat builds up quickly and the air conditioning unit must work harder. Over time, dust, humidity, and dirt reduce your aircon’s cooling performance and can cause issues such as water leaks, mold, and poor air quality.
Regular aircon maintenance is the key to preventing these issues. With our expert air conditioning services in Singapore, you can extend the lifespan of your air conditioner, lower your SP bills, and enjoy a cooler, healthier home.
Proper care also helps you avoid sudden breakdowns during the hottest months—something every Singaporean homeowner wants to prevent.
Common HDB Aircon Problems (and Their Causes)
1. Aircon Leaking Water
One of the most common complaints among HDB homeowners is water dripping from the air conditioning unit. This often happens when the condensate drain line is clogged or when the unit hasn’t been serviced for months. Regular cleaning and maintenance can prevent this issue easily.
2. Weak Cooling or Not Cold
If your aircon isn’t cooling properly, it may be low on refrigerant gas. A simple gas top up by a professional aircon contractor restores cooling efficiency. In other cases, the evaporator coil or air filters may be dirty and restricting airflow.
3. Strange Noises or Vibrations
Loose fan blades, worn bearings, or dust buildup inside the fan coil unit can cause strange sounds. During general servicing, technicians will tighten, clean, and lubricate the moving parts to ensure smooth operation.
4. Foul Odour or Mold
Dirty filters and damp coils create a musty smell. Proper air conditioning maintenance keeps your air fresh and healthy for the family.
5. Electrical Issues
If your aircon trips the circuit breaker, it could indicate faulty wiring or an overloaded air conditioning gsystem. In this case, always call a professional aircon service provider immediately.
How Often Should You Service Your Aircon?
The question “how often should I service my aircon?” depends on usage.
Here’s a quick guide:
Regular aircon servicing in Singapore not only prevents breakdowns but also helps you save on electricity costs. Routine care can improve energy efficiency by up to 20%, helping you keep your home cool and your bills lower.

Use a mild aircon cleaner spray to remove dust buildup.
