Singapore’s tropical climate is known for its intense heat and humidity, especially during peak afternoon hours. Many homeowners and businesses face a common frustration: aircon not cold during hot Singapore afternoons, even though the system works fine in the morning or evening.

Why Aircon Performance Drops in the Afternoon


During midday and afternoon hours, outdoor temperatures in Singapore can exceed 33°C, with high humidity levels. Air conditioners must work harder to remove heat from indoor spaces. If your unit is not properly maintained or installed, it may fail to keep up with the heat load.

While it’s normal for aircons to run longer during hot afternoons, a noticeable loss of cooling efficiency is usually a sign of technical or maintenance-related issues.

Common Reasons Your Aircon Is Not Cold


1. Dirty Air Filters and Coils


One of the most common causes of poor cooling is clogged air filters or dirty evaporator coils. Dust buildup restricts airflow, preventing cool air from circulating properly. During hot afternoons, this restriction becomes more noticeable, making your aircon feel weak.

Regular Aircon servicing by Letscool Aircon and Services ensures filters and coils are thoroughly cleaned to maintain optimal airflow.

2. Insufficient Refrigerant Gas


Low refrigerant levels reduce the system’s ability to absorb and remove heat. When outdoor temperatures rise, an aircon with low gas will struggle significantly, leading to warm air blowing from the unit.

Refrigerant Aircon gas leaks should always be handled by trained professionals to prevent further damage to the system.

3. Overworked or Undersized Aircon Unit


If your aircon capacity does not match the room size, it may cope during cooler hours but fail during peak heat. This is common in Singapore homes where room usage changes over time, such as converting bedrooms into home offices.

Professional assessment by Letscool Aircon and Services can help determine whether your unit is appropriately sized.

4. Faulty Compressor


The Aircon compressor is the heart of the air conditioning system. During hot afternoons, a weak or failing compressor may overheat or lose efficiency, resulting in insufficient cooling.

Ignoring early signs can lead to complete breakdowns and costly replacements.

5. Poor Aircon Installation


Improper installation—such as incorrect piping length, poor insulation, or wrong positioning of the outdoor condenser—can severely affect performance. Heat exposure to the condenser during the afternoons further worsens the problem.

Choosing experienced technicians for installation and servicing makes a significant difference in long-term cooling efficiency.

How Singapore’s Heat Affects Your Aircon


Singapore’s climate places constant stress on air conditioning systems. High humidity means your aircon must remove moisture as well as heat, increasing workload. When maintenance is delayed, the system becomes less efficient, especially during peak afternoon temperatures.

This is why routine servicing is not optional—it is essential for consistent performance in Singapore’s weather.
