Air conditioners are built to last. However, many homeowners in Singapore find themselves calling for repairs more often than expected. So why do aircons break down so frequently?
The truth is, most breakdowns don’t happen suddenly. Instead, they build up over time due to small issues that are ignored. Fortunately, with proper care and regular aircon servicing Singapore, many of these problems can be prevented.
Let’s explore the common reasons behind frequent aircon breakdowns — and how you can avoid them.
1. Lack of Regular Servicing
First and most importantly, skipping regular servicing is the biggest cause of aircon failure. Over time, dust and dirt collect inside the filters, coils, and drainage pipes. As a result, airflow becomes weak and the system works harder than necessary.
When your aircon constantly overworks, internal parts wear out faster. Eventually, this leads to breakdowns and the need for aircon repair Singapore.
Prevention Tip:
Schedule professional aircon maintenance Singapore every 3–4 months.
2. Dirty or Clogged Filters
Dirty filters block airflow. Consequently, the evaporator coil may freeze, and cooling becomes inconsistent. If ignored, the system may shut down completely.
Prevention Tip:
Clean your filters every 2–3 weeks, especially in Singapore’s humid environment.
3. Low Refrigerant (Gas Leaks)
Another common issue is refrigerant leakage. Your aircon may start cooling normally, but once gas pressure drops, performance decreases.
Low refrigerant forces the compressor to work harder, which may cause overheating and long-term damage.
Prevention Tip:
If cooling weakens, book a gas top-up aircon Singapore service immediately and check for leaks.
4. Overheating Outdoor Unit
Meanwhile, the outdoor condenser unit is often exposed to direct sunlight, rain, and debris. If airflow around the unit is blocked, it overheats and shuts down.
Prevention Tip:
Keep the condenser area clean and ensure proper ventilation. Regular aircon servicing Singapore includes outdoor unit inspection.
5. Electrical Issues
Loose wiring, worn capacitors, and unstable voltage can also cause breakdowns. In fact, electrical faults are one of the main reasons older aircons fail.
Warning Signs Include:
Circuit breaker trips
Buzzing noises
Aircon turns off randomly
Prevention Tip:
Have a licensed aircon technician Singapore inspect electrical parts during servicing.
6. Poor Installation
Sometimes, frequent breakdowns start from day one. Improper installation leads to incorrect gas pressure, poor drainage alignment, and airflow issues.
Prevention Tip:
Always choose experienced professionals for aircon installation Singapore to avoid future problems.
