PART 2 – THE ROLE OF AIRCON SERVICING
2.1 Common Air Conditioning System Issues
Air conditioning systems serve as essential fixtures in regions plagued by persistent heat and humidity. Not only do they offer relief from the oppressive heat, but they also play a vital role in preserving the integrity of buildings and infrastructure by removing excessive moisture that can foster mould growth. However, this does not mean that they are safe from problems that can disrupt their operation and efficiency. Take a look at some common issues you need to be aware of below:
1. Aircon Refrigerant Leak
Is your air conditioner not as cold as before? If you answered yes, your system might be experiencing a refrigerant leak, which may occur due to degraded connections within the system. Over time, the seals and fittings connecting various air conditioner components may wear and tear, resulting in the appearance of small gaps or cracks that allow refrigerants to leak out. Physical damage to the unit, whether caused by accidental impacts, corrosion due to harsh weather conditions, or vandalism, can also weaken the air conditioner’s structural integrity and create openings through which refrigerant escapes.
2. Aircon Leaking Water
An aircon that’s leaking water can be linked to a clogged condensate drain. The drain is designed to remove excess moisture generated during the cooling process, directing condensate water away from the unit to maintain ideal indoor humidity. When it is blocked with contaminants like dirt, dust, or algae, the water flow may become obstructed and build up in the aircon unit, eventually leading to overflows and leaks. On top of that, a malfunctioning condensate pump is likely to cause the air conditioner to leak water too. As the pump fails to dispose of accumulated water from the system efficiently, the water will continue to back up within the unit and cause water damage.
3. Damaged Compressor
The compressor is responsible for heat exchange and pressure regulation of refrigerants. During the cooling process, the component compresses low-pressure, low-temperature refrigerant vapour into a high-pressure, high-temperature gas. It then allows liquid refrigerant to absorb heat from indoor air and cool it. However, the compressor may fail when there are dirty coils, changes in refrigerant levels, and lack of lubrication. When there is insufficient refrigerant, the compressor could overheat and even break down; while too much refrigerant may exert excessive pressure within the unit.
4. Capacitor Issue
When a capacitor malfunctions, you may find it difficult to start your air conditioning system as it wouldn’t be supplied with the required electrical boost for motor operation. This then leads to intermittent cooling, making it challenging for the system to maintain a comfortable indoor temperature. By engaging an aircon contractor promptly, you’ll be able to address these capacitor issues, preventing additional damage to other components of the air conditioner.

5. Faulty Thermostat
A thermostat is a device in the air conditioner that senses and controls room temperature by activating the cooling or heating system accordingly. Here are some signs of a malfunction:
- Inconsistent temperature control
- Inaccurate temperature readings
- Unresponsive temperature controls
- Short cycling of the air conditioner
Various factors can contribute to thermostat failures, including age-related wear, wiring issues, and the buildup of impurities internally. Addressing these issues typically require troubleshooting and repairs performed by a qualified HVAC technician. By accurately diagnosing the underlying problems, these professionals can help restore the thermostat’s proper functioning.
6. Dirty Air Filter
Dirty air filters are inevitable as an air conditioning system ages. When these filters become clogged with debris, they hinder airflow through the system, making it difficult for cool air to reach every part of your home effectively. This forces your air conditioner to work harder to maintain the desired temperature. Consequently, energy consumption increases as the system’s components overwork. For peak performance, it’s advisable to arrange routine aircon cleaning services to maintain clean and unobstructed filters.
7. Aircon Fan Failure
Aircon fans are essential in circulating air within the air conditioner, facilitating the cooling and dehumidification process for a comfortable indoor environment. When these fail, it not only compromises the airflow, but also prolongs cooling times and exerts excessive strain on other components. Some causes of the failure include:
- Motor Issues
Wear and tear of the air conditioning system can lead to mechanical failure or electrical issues such as burnt coils or damaged wiring. When there are faulty components, the fan motor will fail to operate.
- Overheating
When airflow is blocked, excessive heat can build up within the air conditioning unit. The issue further brings damage to critical components like the fan motor.
- Lubrication Problems
Be mindful that insufficient lubrication of the fan motor bearings can potentially impact overall performance. It increases friction between moving parts, causing the bearings to deteriorate after some time. This misalignment and irregular operation will cause the fan to fail.
