Air conditioners are essential for comfortable living in Singapore’s hot and humid climate. But like any appliance, they can develop issues over time. If you’ve ever searched for “aircon not cold Singapore” or worried about “aircon leaking water,” you’re not alone.
At Aircon Servicing Singapore, we’ve helped thousands of homeowners and businesses identify and fix common aircon problems quickly and affordably. In this guide, we’ll cover the top 10 aircon issues in Singapore and how you can solve them.
Why Aircon Problems Are Common in Singapore’s Climate
Singapore’s tropical climate puts extra stress on air conditioners:
- High humidity makes condensation and water leaks more likely.
- Constant use in hot weather wears out parts faster.
- Dust and pollution in urban areas clog filters and coils.
- Power fluctuations during storms can cause tripping issues.
That’s why regular aircon servicing is essential—not just to fix problems, but also to prevent them.
10 Common Aircon Problems in Singapore (and Fixes)
1. Aircon Not Cold
One of the most common complaints is when the aircon isn’t cooling properly. This can be caused by:
- Dirty air filters blocking airflow
- Low refrigerant (gas) levels
- Faulty compressor
Fix: Start by cleaning or replacing the filter. If the problem persists, you may need a gas top-up or professional servicing.
2. Aircon Leaking Water
If you notice water dripping from your unit, it’s often due to:
- Clogged drainage pipes
- Damaged or frozen coils
- Improper installation
Fix: Turn off the unit and clean the drainage line. If the leak continues, call a professional to check for coil damage or installation issues.
3. Strange Noises
Grinding, buzzing, or rattling noises usually mean something is wrong:
- Loose fan blades
- Worn-out motor bearings
- Debris inside the unit
Fix: Clear any debris and tighten screws. Persistent noises usually require an expert inspection.
4. Unpleasant Smells
Bad odors from your aircon can be caused by:
- Mold growth due to high humidity
- Dirty filters or coils
- Dead insects inside the unit
Fix: Clean the filters regularly. If the smell is musty, schedule a chemical wash to remove mold and bacteria.
5. Aircon Power Trips
Does your circuit breaker trip when you switch on the aircon? Common causes include:
- Electrical overload
- Short circuits in the wiring
- Faulty components like compressors
Fix: Reset the breaker once. If the problem repeats, switch off the unit and call an aircon technician to prevent electrical hazards.
6. Weak Airflow
If the air feels weak even at high fan speeds, the problem may be:
- Blocked air filters
- Damaged blower fan
- Leaky ducts (for central systems)
Fix: Replace or wash the filter. If airflow is still weak, you’ll likely need repairs to the fan or ducts.
7. Aircon Freezing Up
If you see ice forming on the coils, it’s usually caused by:
- Low refrigerant levels
- Poor airflow due to clogged filters
- Thermostat malfunctions
Fix: Switch off the unit and let it thaw. Then clean the filters. If freezing happens again, you may need a gas top-up.
8. Frequent On/Off Cycling
If your aircon keeps turning on and off quickly, it may be due to:
- Thermostat issues
- Dirty condenser coils
- Overheating from poor maintenance
Fix: Clean the coils and check the thermostat settings. If the problem persists, a professional can recalibrate or replace faulty parts.
9. Remote Control Not Working
Sometimes the issue isn’t the aircon, but the remote control:
- Dead batteries
- Faulty remote sensor on the unit
- Damaged remote
Fix: Replace batteries first. If the problem isn’t solved, test the sensor with another remote or call a technician.
10. Aircon Not Turning On
If your aircon doesn’t switch on at all, the causes may include:
- Faulty power supply
- Blown fuse or tripped breaker
- Internal wiring issues
Fix: Check your power source and circuit breaker. If it’s not an electrical issue, you’ll need a professional diagnosis.
How Aircon Servicing Solves These Problems
Regular aircon servicing in Singapore prevents most of the above issues. Professional servicing includes:
- Filter cleaning/replacement for better airflow
- Drain pipe flushing to prevent leaks
- Gas top-ups to restore cooling performance
- Coil cleaning to remove mold and bacteria
- Full inspection to identify worn-out parts early
With routine maintenance, you can extend your unit’s lifespan and avoid costly repairs.
When to Call a Professional
While some small fixes (like cleaning filters or changing remote batteries) can be DIY, it’s best to call a professional when:
- Your aircon is still not cold after cleaning
- You see water leaks or ice buildup
- The unit causes frequent power trips
- There are persistent noises or smells
- The aircon simply won’t turn on
Ignoring these issues can make problems worse, leading to higher repair costs or even replacement.
