In this humid weather in Malaysia, having an air conditioner within your house is indeed a necessity. There’s nothing quite like the feeling of being surrounded by cool air. Hence, the worst thing that could happen is when your air conditioner isn’t blowing out cooling air. If you’re wondering, “Why my air conditioner is not cooling properly?”, let us help you to diagnose the possible reasons so you can save yourself from the intense heat quickly.  

Reasons Why Your Air Conditioner Is Not Cooling

Understanding the possible reasons why your air conditioner is not cooling effectively could end your endless confusion and worries. Here are some of the common potential reasons: 

1. Your compressor is not functioning well

Compressors are known to be the main part of an air conditioner as they ensure that the refrigerant is functioning at optimal pressure. If the compressor isn’t functioning, it won’t be able to absorb any heat from your home and release it outdoors. Some of the common signs to look out for, if your compressor isn’t functioning properly, would be if the air conditioner can’t be turned on, not blowing out cold air, and if it shakes violently once turned on. 

2. The condenser unit is blocked 

The condenser of an air conditioner is usually located outside of your house. The primary function of a condenser is to absorb the heat from your house and release it outdoors. If the condenser unit is blocked by debris such as leaves or dirt, then it can’t absorb heat effectively. Hence, it’s important to clean your condenser unit regularly or service your air conditioner often and engage with professional aircond services to avoid this from occurring. 

3. Thermostat settings are inaccurate

If your air conditioner is not blowing cold air, one of the reasons could be that your thermostat has improper settings. When the settings of your thermostat are set to warm instead of cool, then it’ll blow out heat. Another reason is that your thermostat settings are set too high. You can adjust the temperature accordingly based on how cold you want the air to be. 

4. Air filters are dirty

Over time, just like any other devices or electrical appliances, dust and debris will accumulate when not cleaned regularly. If your air filters are filled with dust or dirty particles, it’s impossible for your air conditioner to keep your house cool as it can’t blow out cold air efficiently. Be sure to clean the air filters often to prevent this from happening. 

5. The refrigerant or coolant is low/leaking

Refrigerant or coolant is a type of chemical used in air conditioners to transfer heat from indoors to outdoors. If it’s leaking or the level’s too low, the air conditioner will have trouble blowing out cooling air.  

6. Evaporator coils are having issues

All air conditioners will have a set of evaporator coils that absorb heat from the air in your house. If the coils are frozen due to insufficient refrigerant within the air conditioner or clogged with dirt such as mould, they won’t be able to remove heat effectively. Thus, the air conditioner will blow out warm air instead of cold air.

7. Your air conditioner system is too old 

No electrical appliance lasts forever. Sometimes, if an air conditioner is too old, it might be time to replace it with a brand new model. One of the ways to know whether your air conditioner is too old is when it has been more than 10 years since you first purchased it. Of course, if you notice that it’s not blowing out cold air, it’s also a sign to replace it with a new one. 

What to do if the air conditioner is not cooling?

1. Clean the condenser or compressor

One of the main reasons why your air conditioner is not cooling would be a dirty condenser or compressor. You should clean them yourself if you’re confident, but a professional would be able to know how to clean them without causing any potential damage. 

2. Check potential leakage

Leakage is a common cause of air conditioners not blowing out cool air. You can look around the air conditioner for any potential leaks, and if you manage to spot one, be sure to contact a professional so they can fix the leak for you. 

3. Check the air conditioner filter 

Try to check whether your air conditioner filter is clogged with dust or debris as a dirty filter is one of the causes of your air conditioner blowing out warm air. You can clean the filters yourself by washing them with water or consider changing the entire air conditioner filter with a professional aircond service company. 

4. Contact a professional air cond service 

Ultimately, the best way to handle airconds which are not cooling would be to engage with professional aircond services. A professional could inspect your air conditioner and identify the problem right away. Rather than you cracking your head trying to figure out yourself, a professional can help diagnose immediately.
