Why is my aircon is not cold enough?

Once you understand why your aircon is not cold, you need to take the necessary steps to rectify this issue in order to enjoy a cool and comfortable living space.

1. Dirty Air Filter

First and foremost, you should check your aircon air filter. Air-con filters are important for your well-being and ensuring air is able to pass through your air-conditioning unit. Aircon filters trap everything from large particles like leaves to smaller things like mold and dust, preventing them from reaching your housing unit. Litter stuck in your air-conditioning unit can hinder airflow which prevents air from entering your aircon, which is why your aircon is not cold. If you find your air filter is dirty, replace it with a new one. You should check your filter and have it replaced, if necessary, at least once a month. Having your fan setting on auto can also help to prolong the life of an aircon air filter.

2. Refrigerant leak – Aircon not blowing cold air

The aircon refrigerant is an important component of every aircon as it is the substance responsible for absorbing heat and allows your aircon to blow cold air. If you are low on aircon refrigerant or you have an aircon refrigerant leak, you require a trained aircon technician to fix and refill the refrigerant.

3. Air Duct leak

After prolonged use, the air ducts in your air-conditioning unit may become poorly sealed or lose their insulation, resulting in the air escaping the air ducts. With a lack of air entering your air-conditioning unit, your aircon cannot blow cold air. This is especially so if your air-conditioning unit is rather old. As it is difficult to inspect the air ducts on your own, you require an experienced aircon technician to assist you with this.

4. Dirty Evaporator Coils (Most Common)

The evaporator coils are an essential component in cooling air along with the refrigerant fluid. It is, however, normal for the evaporator coils to become dirty over time which causes the aircon not cold enough. Consequently, your aircon may even overheat and shut off. It is not possible to clean the evaporator coils on your own, hence, you require an experienced aircon technician to assist you with this.

5. Thermostat Controls

If your aircon is not blowing cold air, it could simple be due to wrong thermostat settings. We recommend that you switch your aircon fan control to “Max fan speed”. This will save money as well as it guarantees that the fan is switched on. And all of the cool air is blowing out into your room.
