Air conditioners are a must-have appliance in many homes and offices, especially in countries like Malaysia with hot weather.

However, like any other appliance, air conditioners are prone to developing problems over time.

“Why is my aircon not cold?”

“Why is my aircon leaking?”

If you’ve noticed problems like these, it’s best to start looking into them as they can reduce the performance of your aircon, increase energy consumption and even cause safety hazards. In this article, we will discuss some of the more common aircon problems and how to prevent them through regular air conditioning maintenance.

1. Reduced Cooling Performance

One of the most common aircon problems is reduced cooling performance. If your air conditioner isn’t providing as much cooling as it used to, it could be due to a dirty filter or evaporator coil.

Dirt and debris can restrict the airflow and reduce the cooling efficiency of the unit. To prevent this problem, it is recommended that you clean or replace your aircon filter at least once a month.

Additionally, you should have your aircon professionally cleaned and serviced by a professional air conditioner cleaner at least once a year to ensure that the evaporator coil and other components are free of dirt and debris.

2. Increased Energy Consumption

Another common aircon problem is increased energy consumption. A dirty air conditioner has to work harder to cool the air, which can lead to increased energy consumption and higher utility bills.

Preventing this problem is easy: clean or replace your aircon filter regularly to ensure that the unit is free of dust and debris to continue running efficiently. You should also ensure that your aircon is the right size for your room or space, as an oversized unit can lead to increased energy consumption.

3. Water Leakage

If your air conditioner is leaking water, it could be due to a clogged drain line. Dirt and debris can build up in the drain line over time and cause water to backflow into the cooling unit and cause unwanted water leakage.

To stop this, you should have your aircon maintained by an air conditioner cleaning service at least once every 6 months to ensure that the drain line is free of unwanted clogs. You can also prevent water leakage by ensuring that your aircon is installed correctly and that the unit is level.

4. Unpleasant Odours

A dirty air conditioner can produce unpleasant odours due to the accumulation of mould, mildew, or bacteria in the unit. Additionally, it’s a sign that potentially harmful bacteria or allergens are starting to grow in your air conditioner.

You should clean your aircon when this happens to avoid unpleasant odours from circulating around your home. Sterilising your unit will also help to prevent bacterial growth from going out of control and potentially causing health issues for your family. We would suggest looking for aircon cleaning services which provide sterilisation rather than doing it yourself, as doing it incorrectly may result in unwanted consequences.

5. Noisy Operation

A noisy air conditioner is a sign that your unit could be due to a dirty fan or blower wheel. Dirt and debris can cause these components to become unbalanced and produce loud noises when stuck in certain areas.

In cases like this, it would be better to rely on professional aircon cleaning services to help you. Depending on the severity of debris build-up, certain parts would need to be removed from the aircon unit to manually clean off the gunk.

6. ​​Frozen Evaporator Coil

A frozen evaporator coil is a problem that occurs when condensation on the coil freezes, obstructing airflow and reducing cooling performance. This can be caused by a dirty air filter, low refrigerant levels, or a malfunctioning blower motor.

To prevent this problem, you should clean or replace your air filter regularly and have your air conditioner maintained and serviced at least twice a year to ensure that refrigerant levels are correct and all components are functioning properly.
