Aircon repair
In Singapore’s hot and humid climate, a well-functioning air conditioner is not a luxury—it’s a necessity. When your aircon starts showing warning signs, delaying repairs can lead to higher energy bills, major breakdowns, or even complete system failure. Knowing the early symptoms can save you time, money, and discomfort. In this guide, Letscool Aircon shares the most common signs your aircon needs immediate repair and when to call for professional aircon servicing in Singapore

1. Aircon Not Cold Even After Long Usage
One of the clearest signs of trouble is when your aircon not cold even after running for a long time. This issue could be caused by low refrigerant levels, dirty filters, blocked coils, or compressor problems. A simple aircon gas top-up might solve the issue, but in more serious cases, aircon compressor servicing may be required.
Ignoring weak cooling can strain the system further, leading to higher repair costs. Scheduling aircon general servicing with the best aircon servicing Singapore provider, like Letscool Aircon, helps restore cooling efficiency and prevents further damage.
2. Aircon Water Leakage from Indoor Unit
Aircon water leakage is a common problem in many homes and offices across Singapore. Water dripping from the indoor unit may be caused by clogged drainage pipes, dirty fan coils, or frozen evaporator coils. If left unattended, leaks can damage walls, ceilings, and electrical components.

Professional aircon repair Singapore services can quickly diagnose the cause. In many cases, a deep aircon chemical wash or aircon steam wash is recommended to remove built-up dirt, mould, and sludge from internal components, restoring proper drainage.
3. Aircon Light Blinking or Error Code Displayed
If you notice the aircon light blinking or an aircon error code appearing on the display panel, do not ignore it. These warning signals are designed to alert you to internal faults such as sensor issues, electrical malfunctions, or compressor problems.

Each brand has specific error codes, and guessing the issue can make things worse. Letscool Aircon’s trained technicians can accurately diagnose these alerts and replace faulty aircon spare parts using genuine components for long-term reliability.
4. Strange Noises or Unusual Smells During Operation
Your aircon should operate quietly and without odour. Grinding, rattling, or buzzing sounds often indicate loose parts, motor issues, or internal wear and tear. Musty or burnt smells may signal mould growth, wiring problems, or overheating components.
In such cases, basic cleaning is not enough. A full aircon chemical overhaul may be necessary to dismantle and thoroughly clean internal parts. Regular servicing also helps identify worn-out components early and avoid sudden breakdowns.
5. Rising Electricity Bills Despite Normal Usage
A sudden spike in your electricity bill without increased usage is a hidden sign that your aircon system is struggling. Dirty coils, failing compressors, or inefficient airflow force the unit to work harder, consuming more power.
Signing up for an aircon service contract with Letscool Aircon ensures scheduled maintenance, optimal performance, and long-term savings. Many customers also benefit from seasonal aircon promotion packages that make professional servicing more affordable in Singapore.

6. Frequent Breakdowns or Old System Issues
If your aircon requires constant repairs or is over 8–10 years old, frequent breakdowns may indicate it’s reaching the end of its lifespan. Replacing multiple aircon spare parts repeatedly can be more expensive than investing in a new system.
Letscool Aircon provides expert advice on whether repair or aircon installation in Singapore is the better option. Modern aircon systems are more energy-efficient, quieter, and designed for Singapore’s climate, offering better long-term value.
