Aircon Maintenance
Air conditioners in Singapore work harder than in most countries due to year-round heat and high humidity. Without proper maintenance, aircons quickly lose cooling power, consume more electricity, and develop issues like water leakage and bad smells.
Follow this step-by-step aircon maintenance guide to keep your unit running efficiently and extend its lifespan.

Step 1: Clean the Air Filters Regularly (Every 2–4 Weeks)
Air filters trap dust, dirt, and airborne particles. In Singapore’s dusty and humid environment, filters clog quickly.
How to do it:
- Switch off the aircon and power supply
- Open the front panel
- Remove the air filters
- Wash with water (use mild soap if needed)
- Dry completely before reinstalling
Why it matters:
- Improves airflow
- Enhances cooling
- Reduces electricity bills
Step 2: Keep the Indoor Unit Clean
Dust on the air vents and casing can enter the system, affecting its performance.
What to do:
- Wipe the air vents and outer panel weekly
- Avoid spraying water directly into the unit
- Keep the area around the aircon dust-free
Step 3: Check for Water Leakage Signs (Weekly Check)
Water leakage is a common aircon issue in Singapore, often caused by clogged drainage pipes. Aircon water leak
Look out for:
- Water dripping from the indoor unit
- Damp walls or ceiling stains
- Musty smell
If leakage persists, professional servicing is required.
Step 4: Ensure Proper Airflow Around the Unit
Blocked airflow forces your aircon to work harder.
Best practices:
- Do not block the aircon with furniture or curtains
- Keep doors and windows closed when the aircon is running
- Use ceiling fans together with the aircon for better circulation
Step 5: Set the Correct Temperature
Setting your aircon too cold increases energy usage and strains the system.
Recommended setting in Singapore:
- 24°C to 26°C
This provides comfort while maintaining energy efficiency.
Step 6: Clean the Outdoor Condenser Unit (Every 3–6 Months)
The outdoor unit releases heat. If it’s dirty, cooling efficiency drops.
What to check:
- Remove leaves and debris
- Ensure proper ventilation
- Do not cover the unit
For high-rise buildings, this should be handled by professionals for safety.
Step 7: Listen for Unusual Noises
Strange sounds often indicate internal issues.
Warning signs:
- Grinding or rattling sounds
- Loud buzzing
- Clicking noises
Early detection prevents costly repairs.
Step 8: Schedule Professional Aircon Servicing (Every 3–4 Months)
DIY cleaning is not enough for internal components like coils and blowers.
Professional servicing includes:
- Coil cleaning
- Fan blower washing
- Drainage system flushing
- Performance checks
This is essential in Singapore’s humid climate.
Step 9: Do AC Chemical Cleaning When Needed
Normal servicing may not solve severe cooling or odour issues.
Chemical cleaning is recommended if:
- Aircon is not cold
- Airflow is weak
- Bad smell persists
- Water leakage keeps happening
It restores cooling efficiency significantly.
Step 10: Replace Worn-Out Parts Early
Faulty parts reduce performance and increase power consumption.
Common parts to check:
- Capacitors
- Fan motors
- Sensors
- Drain pipes
Timely replacement prevents breakdowns.
Step 11: Maintain a Regular Servicing Schedule
Consistency is key to long-lasting performance.
Suggested maintenance schedule in Singapore:
- Filter cleaning: Every 2–4 weeks
- General servicing: Every 3–4 months
- Chemical cleaning: Once a year or when needed
Benefits of Proper Aircon Maintenance
- Strong and consistent cooling
- Lower electricity bills
- Better indoor air quality
- Fewer breakdowns
- Longer aircon lifespan
Conclusion
Maintaining an air conditioner in Singapore requires regular care due to constant usage and high humidity. By following these step-by-step instructions and scheduling professional servicing, you can keep your aircon efficient, hygienic, and reliable all year round.
Regular maintenance not only saves money but also ensures comfort in Singapore’s tropical climate.
