REASONS WHY YOUR AIR CONDITIONER IS NOT COOLING AND HOW TO FIX IT?

In the intense heat of Singapore, where temperatures can soar to 88 degrees Fahrenheit, an air conditioning unit that fails to produce cold air is more than a mere inconvenience; it significantly affects your comfort. Ensuring that your air conditioning system operates effectively and efficiently is crucial for maintaining a pleasant environment during the summer months.

WHY AIR CONDITIONER IS NOT COOLING?

The refreshing sensation of being in a cool indoor space while the outdoor temperature rises is truly unmatched. As the summer heat intensifies, you might be inclined to run your air conditioning continuously throughout the day. However, prolonged operation can lead to decreased efficiency and eventually the AC would stop delivering cold air. There are various potential reasons for this issue, and identifying the specific cause is essential for implementing the appropriate solution. Below are several common factors that may contribute to insufficient cooling from your air conditioning unit requiring aircon repair Singapore, along with suggested remedies to address the problem.

1. CLOGGED FILTER

Clogged filters are perhaps the most frequent source of air conditioning issues. Filters can become obstructed by dirt, pet hair, pollen, and dust. When this occurs, the airflow through the air conditioning system is restricted, resulting in inadequate cooling of the indoor environment. Furthermore, clogged filters can negatively impact the performance of the indoor evaporator coil and the outdoor condenser unit. To mitigate problems related to clogged filters, it is essential to clean them on a regular basis and replace them when needed.

2. THERMOSTAT SETTINGS

When your air conditioner fails to provide adequate cooling, the initial step is to examine the thermostat settings of your unit. It is possible that the thermostat is not configured for optimal cooling. Ensure that your air conditioning system is set to the cooling mode and that the temperature is adjusted to a sufficiently low level for comfort.

3. LOW REFRIGERANT LEVEL

The refrigerant serves as the medium through which your air conditioning system extracts heat from the indoor air of your home. When refrigerant levels are insufficient, the air conditioner’s cooling efficiency diminishes. This issue frequently arises from undetected leaks in the refrigerant lines. Merely refilling the refrigerant is not a sustainable fix, as the underlying leak will persist, leading to a gradual decrease in refrigerant levels. It is crucial to engage a qualified technician to identify and rectify the leaks before replenishing the refrigerant to the correct levels.

4. DEBRIS IN THE CONDENSER

If your air conditioning unit is not producing cool air, it is advisable to conduct a visual examination of the condenser. The condenser is a crucial component of your system that facilitates the circulation of air through your vents. It consists of a fan and coils situated outdoors; however, if debris accumulates around these elements, it may hinder their capacity to deliver cool air into your residence. Should you notice any debris on or near the coils, it is prudent to remove it. This can be accomplished using a soft brush with stiff bristles or by rinsing them with water. If the accumulation exceeds mere dirt and dust, it may be necessary to call for aircon service Singapore professionals for an assessment of the required repairs.

5. FAULTY COMPRESSOR

The compressor plays a crucial role in moving refrigerant between the indoor and outdoor units, which is essential for effectively cooling your home. It may encounter failures due to dirt or mineral buildup on the coils, blockages or incorrect sizing of suction lines, improper refrigerant and oil lubricant levels, or electrical malfunctions. These problems often require significant repairs or replacement, usually necessitating the services of a licensed HVAC technician for safe and accurate resolution. Conducting annual maintenance on your air conditioning system will also help to enhance the longevity of your AC compressor.

6. WRONG AIRCON SIZE

An air conditioning unit that is too small for a given room may not provide sufficient cooling. Conversely, an oversized unit can cool the area too quickly, neglecting proper dehumidification and leaving the room feeling uncomfortable and humid.

7. ISSUES WITH EXTERIOR FAN MOTOR

The outdoor fan situated in the condenser unit of your air conditioning system is tasked with drawing hot air from your residence and venting it outdoors. Unfortunately, this fan may encounter malfunctions, which can lead to the compressor of your AC overheating. The most effective way to resolve this issue is to seek assistance from a qualified technician experienced in AC troubleshooting. If the fan motor becomes defective, the fan will stop functioning, causing the air conditioner to overheat and shut down shortly thereafter.

8. FROZEN EVAPORATOR COIL

Although it is less frequent, a frozen evaporator coil can occur. This indoor coil, which plays a crucial role in cooling the air, may freeze if the air conditioning system operates at excessively low temperatures or if there is a restriction in airflow. Such freezing inhibits the coil's ability to absorb heat from the warm air, thereby diminishing cooling efficiency. To defrost a frozen coil, it is advisable to turn off the air conditioning unit entirely and set the fan to "on" to promote air circulation. If the ice does not melt after a few hours or if the issue continues, it is recommended to seek assistance from a qualified technician.

9. LEAKING DUCTWORK

An old ductwork system in your home may lead to the development of leaks within the air ducts. Such leaks could be responsible for your air conditioner’s failure to cool effectively, despite its operation. Maintaining a properly sealed ductwork system is vital to ensure that cool air does not escape into the attic. If you believe your ductwork may be leaking, you can request a comprehensive air duct inspection, which will include a full evaluation and an estimate for replacing any damaged sections.

CONCLUSION

Given Singapore's hot climate, it is crucial to uphold the performance of your air conditioning system to ensure effective cooling. Basic maintenance, such as cleaning filters and checking thermostats, can often rectify minor cooling problems. However, if issues persist, it is advisable to seek professional assistance to thoroughly diagnose and repair any underlying complexities. This will ensure that your air conditioner continues to provide a pleasant and cool atmosphere.
