How to Perform Routine Aircon Maintenance in Singapore

Air conditioning systems are vital components of modern living, especially in Singapore’s tropical climate, where temperatures can soar year-round. To ensure your aircon operates at its peak efficiency and reliability, it’s imperative to conduct regular maintenance. Below, we delve into a comprehensive guide on routine aircon maintenance in Singapore, covering every aspect to keep your system running smoothly and efficiently.

1. Clean or Replace Air Filters

The air filters in your air conditioning system serve as the first line of defence against dust, dirt, allergens, and other airborne particles. Over time, these filters can become clogged with debris, hindering airflow and reducing the system’s efficiency. Neglecting to clean or replace air filters can result in poor indoor air quality, reduced cooling capacity, and increased energy consumption.

To maintain optimal performance, it’s recommended to clean or replace air filters every one to three months, depending on usage and environmental factors. For households with pets or allergy sufferers, more frequent filter changes may be necessary. Cleaning or replacing air filters is a simple yet crucial maintenance task that can significantly prolong the lifespan of your aircon system and improve indoor air quality.

2. Check and Clean Evaporator Coils

The evaporator coils in your air conditioning system play a vital role in cooling indoor air by absorbing heat from the surrounding environment. Over time, these coils can accumulate dirt, dust, and other debris, reducing their efficiency and inhibiting heat transfer. Dirty evaporator coils can lead to decreased cooling performance, higher energy consumption, and potential system malfunctions.

To prevent these issues, it’s essential to inspect and clean evaporator coils annually. Depending on usage and environmental factors, more frequent cleaning may be necessary. Cleaning evaporator coils typically involves using a soft brush or vacuum cleaner to remove accumulated dirt and debris. A mild detergent or coil cleaner may be required to thoroughly clean the coils and restore optimal performance.

3. Inspect Condenser Coils

Condenser coils are responsible for releasing heat absorbed from indoor air into the outdoor environment, allowing your aircon system to maintain a comfortable indoor temperature. Like evaporator coils, condenser coils can become dirty over time, hindering heat dissipation and reducing overall system efficiency. Dirty condenser coils can lead to increased energy consumption, decreased cooling capacity, and system malfunctions.

To ensure your air conditioning system operates efficiently, regular maintenance of condenser coils is essential. In Singapore, where aircon usage is high due to the tropical climate, scheduling annual inspections and cleaning sessions for condenser coils is crucial. Depending on factors like environmental conditions and location, more frequent cleaning may be necessary. The process involves using specialised coil cleaners or a water and detergent mixture to eliminate accumulated dirt and debris, ensuring optimal heat dissipation. Additionally, it’s imperative to maintain clear surroundings around the condenser unit, free from any obstructions like debris or vegetation. This promotes adequate airflow, enhancing heat dissipation efficiency. If you encounter any issues with your air conditioning system, consider contacting reputable aircon repair services in Singapore for professional assistance and prompt resolution.

4. Clean and Straighten Coil Fins

Coil fins are thin metal pieces that surround evaporator and condenser coils, facilitating heat transfer and airflow within the aircon system. Over time, these fins can become bent or damaged, obstructing airflow and reducing overall system efficiency. Bent or damaged coil fins can lead to decreased cooling performance, higher energy consumption, and potential system malfunctions.

To maintain optimal airflow and system efficiency, it’s essential to inspect and clean coil fins regularly. Straightening bent fins and removing debris can help improve airflow and ensure proper heat transfer within the system. Specialised tools, such as a fin comb, can be used to straighten bent fins and restore optimal performance. In addition to cleaning and straightening coil fins, it’s vital to ensure that the area surrounding the aircon unit is free of obstructions to promote adequate airflow and prevent overheating.


Routine aircon maintenance is essential for ensuring optimal performance, energy efficiency, and longevity of your air conditioning system in Singapore. By following these comprehensive maintenance tips and conducting regular inspections and cleaning tasks, you can keep your aircon running smoothly and reliably, even in the sweltering tropical heat. Remember to schedule professional aircon repair services to address any issues and maintain your system’s functionality for years to come. Contact Newway Air Conditioning today for more information.
