As the sweltering Singaporean summer approaches, ensuring your air conditioning system is in top-notch condition becomes paramount. Neglecting aircon maintenance can lead to a slew of common problems like reduced cooling efficiency, water leakage, foul odours, and annoying noises. 

Fear not! With the right maintenance regimen, you can keep your aircon running smoothly throughout the hottest months. Let’s delve into some essential maintenance tips to keep your cool this summer.

Understanding Common Aircon Problems:

Before we talk about how to take care of your aircon, it’s important to understand the common issues it can have. From not cooling well to leaks and strange smells, aircons can face various problems. By learning about these issues, you can better deal with them and keep your aircon running smoothly.

Reduced Cooling Efficiency: When your aircon starts blowing warm air instead of the refreshing cool breeze you crave, several factors could be to blame. From a malfunctioning compressor to insufficient refrigerant levels or even something as simple as clogged air filters, a myriad of issues can lead to reduced cooling efficiency.

Water Leakage: Nothing dampens the spirits quite like water leakage from your aircon unit. This pesky problem is often caused by clogged drain pipes, a malfunctioning condensate pump, or poor installation practices.

Foul Odours: If your aircon is emitting foul odours reminiscent of a neglected gym locker, mould or bacterial growth within the unit could be the culprit. The humid climate in Singapore creates the perfect breeding ground for these unwelcome guests.

Noise Issues: Strange noises emanating from your aircon unit can range from annoying buzzing to alarming grinding sounds. These auditory disturbances may indicate anything from worn-out components to loose parts or debris obstructing vital machinery.

Compressor Problems: The compressor serves as the heart of your aircon system, and any issues with this vital component can have dire consequences. From erratic cooling to frequent cycling or complete system failure, compressor problems are not to be taken lightly.

Aircon Error Codes: Modern aircon units are equipped with sophisticated diagnostic systems that display error codes when something goes awry. Understanding these codes can provide valuable insights into the health of your aircon system.

AC Thermistor Problems: The thermistor plays a crucial role in regulating the temperature within your aircon unit. When this component malfunctions, you may experience erratic cooling, overheating, or other temperature-related issues.
