If your aircon is not working, this guide will greatly help you. Air conditioning is essential in Singapore’s hot and humid climate. When your aircon stops working, it can be frustrating and uncomfortable.
There are many reasons why your aircon might stop working. Some can be easy to fix, while others require professional attention. This article will explore the top seven reasons why your aircon might not be working.
Why My Aircon is Not Working?
If you are wondering why your aircon is not working, read the top reasons explained by LS Aircon Servicing Singapore, which also offers aircon repair, aircon chemical wash, aircon chemical overhauling, and general aircon services. Here are the answers to why your aircon is not working.
1. Dirty Air Filters
One of the most common reasons why an air conditioner stops working efficiently is due to dirty air filters. The air filter in your aircon filters dust in the outside air and purifies the inside air. Over time, these filters can clog, reduce the airflow and cause the system to struggle.
If your aircon isn’t cooling well, you should start the restoration process by cleaning and replacing the air filters if necessary. Regular maintenance of the air filter can prevent this issue.
2. Thermostat Issues
Sometimes, the problem lies with the thermostat. If the thermostat is set incorrectly, the aircon may not respond as it should. Ensure that your thermostat is set to “cool” mode and the temperature is lower than the current room temperature. If the thermostat is old, replace it with a new and programmable version to ensure proper aircon operation.
3. Refrigerant Leaks
A refrigerant leak might be the root cause if your air conditioner is not working. Refrigerant is a crucial component of your aircon system, as it absorbs the heat from outside air and cools your space. If there is a leak in the refrigerant line, your aircon won’t be able to cool effectively.
If this is the issue, you may notice warm air blowing from the unit. Refrigerant leaks are bad for the environment and can cause long-term damage to your aircon. In such cases, it’s best to call a professional to inspect and repair the leak.
4. Frozen Evaporator Coils
Evaporator coils absorb the heat from the air, and if they freeze, your aircon will struggle to work properly. This happens when airflow is restricted due to dirty air filters and blocked return air ducts. Frozen coils can also be a result of low refrigerant levels.
When the coils freeze, your aircon stops working; if it works, it blows warm air. If you think frozen evaporator coils are the culprit, turn off the unit, defrost it and address the issues yourself or through a professional. Ignoring this issue can further damage your aircon system.
5. Electrical Problems
Your aircon unit relies on electricity to power its components. If there’s an electrical issue, your aircon may fail to operate. You should check your electrical panel for tripped breakers or blown fuses to know if there is an electrical issue.
However, electrical problems can be dangerous, so if you’re unsure about handling them, it’s best to consult an electrician or HVAC professional to diagnose and fix the problem safely.
6. Blocked Condenser Unit
The condenser unit, typically located outside, expels heat from your aircon system. If the condenser is blocked, it won’t be able to release heat effectively. This can lead to poor cooling performance or even cause the system to shut down.
To avoid this issue, regularly inspect and clean the area around the condenser and ensure enough space for proper airflow. Professional cleaning might be required if the blockage is severe.
7. Fan Motor Issues
The fan motor is another crucial component of your aircon system and is responsible for moving air through the system. If the fan motor fails, your aircon won’t be able to circulate air properly. This reduces the aircon efficiency and makes it work extra hard.
If you notice strange noises from the unit or weak airflow, the fan motor could be the reason. In most cases, you should hire a professional to repair or replace the fan motor of your aircon to restore normal operation.
Conclusion
When your aircon is not working, it can disrupt your comfort and daily routine, especially in Singapore’s scorching heat. The above instructions detail the most common reasons for aircon failure. Remember the above reasons and hire a professional if you cannot resolve the issue yourself. Moreover, regular maintenance and inspections are essential to prevent this issue.
