3 Reasons Why Your Aircon is Not Cold


As the sweltering heat of the haze season sets in, your trusty air conditioner becomes an invaluable companion in providing cool and comfortable indoor spaces. However, there might be instances when you notice that your aircon is not cooling as effectively as it should.

So, why is your aircon not cold?

This can be a frustrating experience, leaving you wondering what could be the cause of this inconvenience. In this article, we will explore three common reasons why your air conditioner might not be cold, along with some troubleshooting tips to help you rectify the issues.

1. Dirty Air Filters:

One of the most frequent culprits behind an aircon not cooling properly is dirty or clogged air filters. Over time, the filters in your air conditioning unit accumulate dust, dirt, and other debris from the air, causing them to become blocked. When the filters are obstructed, they restrict the airflow, making it harder for the air conditioner to cool the room effectively.

Solution: To resolve this issue, check your air filters regularly, and clean or replace them as needed. Cleaning the filters every one to two months is generally recommended, but the frequency may vary depending on usage and environmental factors.

2. Refrigerant Leak:

The refrigerant in your air conditioning system plays a crucial role in the cooling process. It absorbs heat from the indoor air and carries it outside, leaving the air inside your home cool and comfortable. However, if there’s a refrigerant leak, the aircon’s cooling capacity will be compromised.

Signs of a refrigerant leak include reduced cooling performance, hissing or bubbling noises near the unit, or icy buildup on the evaporator coils.

Solution: If you suspect a refrigerant leak, it’s crucial to call a professional air conditioner repair expert to locate and fix the issue. Remember that adding more refrigerant without fixing the leak is not a permanent solution and can harm the environment.

3. Condenser Unit Issues:

The condenser unit of your air conditioner is usually located outside and is responsible for releasing the heat absorbed from the indoor air. If the condenser unit is dirty or obstructed, it won’t be able to dissipate heat effectively, resulting in reduced cooling performance.

Solution: Ensure that the area around the condenser unit is clear of debris, leaves, or any obstructions. Regularly clean the condenser coils and fins to maintain optimal airflow. If you’re not familiar with these maintenance tasks, you can always seek the help of a professional technician.


A poorly performing air conditioner that is not cooling your home can be a frustrating experience, especially during the hot summer months. However, by understanding the common reasons behind this issue, you can take appropriate steps to troubleshoot and resolve the problems. Regularly cleaning or replacing air filters, addressing refrigerant leaks promptly, and maintaining the condenser unit will go a long way in keeping your aircon functioning efficiently.

While some troubleshooting can be done on your own, it is essential to remember that certain air conditioner issues require the expertise of a professional repair technician. Regular maintenance by a qualified professional can also prevent many of these problems from occurring in the first place, ensuring that your aircon keeps you cool when you need it the most. Stay cool and enjoy the comfort of your well-functioning air condition
