11 Reasons Why Aircon Is Not Cold
1. Undersized AC Unit
If your air conditioner HP is not strong enough for the room you are trying to cool; it will have a hard time keeping the entire space cool. This is because the unit will be working overtime to try and cool the larger space, and it will eventually start to blow warm air.
The best way to avoid this problem is to make sure that you get an air conditioner that is the right size for the room you are trying to cool. By doing this, you can ensure that your unit will not have to work too hard to cool the space, and it will be able to provide you with cold air all summer long.
2. High Atmospheric Temperature
If the atmospheric temperature is too high, then the air conditioner will not be able to cool the air. This is because it relies on the difference between the atmospheric temperature and the temperature of the refrigerant to work correctly. This often happens in Johor Bahru, Malaysia, which has hot weather all year round.
To fix this problem, you can try turning on a fan in the room to help circulate the air and lower the temperature.
3. Damaged Thermistor
The thermistor is a sensor located near the evaporator coils, and it helps regulate the temperature of the air conditioner. If this sensor is damaged, it can cause the air conditioner to blow warm air.
You will need to replace the thermistor with a new one to fix this problem. You can find replacement thermistors at most hardware stores.
4. Clogged Air Filter
The filter traps airborne particles that might harm the air conditioner. However, if you don’t clean the filter for a long period, it can become clogged and stop the airflow. If this happens, the evaporator coil may freeze and cease to function.
To prevent this from happening, regularly clean your air filter according to the manufacturer’s instructions. By doing so, you can ensure that your aircon unit will continue to function correctly and provide you with cold air all summer long.
5. Faulty Compressor
The compressor is responsible for circulating the refrigerant in the air conditioner. If it is broken, then it will not be able to do its job properly, and the air conditioner will not be able to cool the air. In some cases, you may be able to repair the compressor, but in other cases, you may need to replace the entire air conditioner.
6. Broken Fan
If the fan in your air conditioner is not working, then the unit will not be able to circulate the air properly. This can cause the unit to blow warm air instead of cold.
7. Faulty Capacitor
The capacitor helps to start the compressor when the air conditioner is turned on. If it is faulty, then the compressor will not be able to start, and the air conditioner will not be able to cool the air. In most cases, you will need to replace the capacitor to fix the problem.
You can check the capacitor by using a multimeter to test if it is working properly. If it is not, then you will need to replace it with a new one.
Replacing the capacitor is not a difficult task, and you can do it yourself if you have some basic knowledge about electrical circuits. However, if you are not confident about doing it yourself, then you can always call a professional to do it for you.
8. Dirty Condenser Coils
The condenser coils are responsible for releasing the heat that the refrigerant has absorbed. However, if these coils are dirty, it can prevent the heat from being released properly and cause the air conditioner to blow warm air. To clean the condenser coils, you can either use a brush or a vacuum cleaner with a soft-bristled attachment.
Make sure to turn off the power to the air conditioner unit before you start cleaning. Once the coils are clean, you should see an improvement in the performance of your unit, and it should start blowing cold air again.
9. Dirty Evaporator Coil
The evaporator coil is responsible for absorbing the heat from the air. However, if it is dirty, then it will not be able to do its job properly, and the air conditioner will not be able to cool the air. To clean the evaporator coil, you can use a special solution that is designed specifically for this purpose.
Make sure to follow the instructions on the solution carefully so that you do not damage the coil. Once you have cleaned the coil, make sure to dry it thoroughly before putting it back in the air conditioner.
10. Thermostat Issues
The thermostat is responsible for regulating the temperature in your home. If it is not working properly, it can cause the air conditioner to blow warm air. There are a few different reasons why the thermostat might not be working correctly. It could be due to a loose wire or Connection, incorrect settings, or a low battery.
If you think that the thermostat might be the issue, you should first check the batteries. If they are low, replace them and see if that fixes the problem. If not, you can try resetting the thermostat to see if that does the trick.
11. Refrigerant Leaks
The refrigerant is what helps to cool the air in your home. If there is a leak, it can cause the air conditioner to blow warm air. A refrigerant leak can be caused by various things, such as a hole in the unit or a faulty valve.
If you think that there is a refrigerant leak, the best thing to do is to call an aircon expert. They will be able to locate the leak and repair it so that your air conditioner will be back to blowing cold air in no time.
Additional tips to keep your home cool when your aircon is not cold:
Use a Ceiling Fan
If you have a ceiling fan, then you can use it to help circulate the air in your home and make it feel cooler.
Close the Blinds or Curtains
Another way to keep your home cool is to close the blinds or curtains. This will help to block out the sun and prevent the heat from coming in.
Use a Humidifier
If the air in your home is too dry, it can make it feel warmer than it actually is. Using a humidifier can help to add moisture to the air and make it feel cooler.
Final thoughts
There are several different things that can cause the air conditioner to blow warm air. However, most of these issues can be easily fixed with a little bit of troubleshooting.
