8 Steps to Fix an Air Conditioner That Isn’t Cooling

A poorly functioning air conditioner can feel like an inconvenience, especially in the burning summer heat, where all one’s need relief. For the most part, there are a number of things you can troubleshoot before calling for help. One of the simplest and most common fixes could be giving your unit a thorough clean AC treatment. So, if you feel your air conditioning has gone awry, worry not because few simple steps shall help to get it back to normal.

Following are the 8 steps to fix your Aircon;

1. Confirm the Thermostat Settings 

Confirming if the thermostat was set properly is one of the easiest fixes. Go to your thermostat and set it to the “cool” setting. Make sure that the temperature set is lower than the present temperature of the room. In case dry cooling does not work, try to increase the difference between the two temperatures. If everything works as it should and the issue occurs then it’s the right time to contact professionals at 7DAYS Aircon Servicing Pte Ltd for proper assessment and help.

2. Change or Clean the Air Filters

Air filters with clogs are one of the main causes of air conditioners not cooling effectively. Filters that are not clean will also limit airflow which brings about inefficient cooling of the system. To counter this, the filters should be changed or unclogged on a routine basis; this basic effort can noticeably boost the performance of the AC unit and longevity as well.

3. Look at the Coils for Blockage Such as Dirt or Dust

Consequently, the system will circulate warm air as the coils are unable to work competently. Here are the parts you need to check:

• Evaporator Coils: These are placed in the boundaries of the air handler and because of the moisture and dust found in the room, they can get spoiled quickly. Always ensure that they are clean otherwise the blockage may affect airflow.
• Condenser Coils: These are placed in the exterior of the unit. They can become blocked by dirt, leaves, and grease. If they are not cleaned, inability to release heat sources may force them to overheat.
• Cleaning Frequency: Cleaning the coils regularly is important. Try to inspect the coils once in a year and even consider booking cleaning service for professionals.

4. Confirm the Refrigerant Level

Problems may arise if there is depletion of refrigerant in the unit. In case you are not sure, then it is better to hire an expert to examine the insides. It is important to note, however, that refrigerant leaks may occur which must be sealed as well so that there aren’t any difficulties in the future.

5. Clean the Condenser Unit 

The cooling of the condenser unit situated outside would be very ineffective as long as there will be steady growth of back plants, leaves or other twigs that block the airflow the same way the overbore ones do. Out of all those three, the twigs will have the least discrimination been cut off.

6. Reset the Circuit Breaker

Dirt or debris prevents each evaporator and condenser coil from performing their center feature of either soaking up or freeing heat. And here’s what you can do to diagnose and fasten the situation;

• Check the Evaporator Coils: These are located within an air handler and are also responsible for collecting dirt carried by air passing over them.
• Condenser Coils: They are located externally and are responsible for releasing any heat the refrigerant absorbed. When such coils are covered in dirt leaves, they are unable to release heat meaning, the AC is unable to perform its job well.
• Visible Build-Up: The molds, dirt, or even rust next to the evaporator or condenser coils can easily block any airflow and cause the AC not to cool as intended.

7. Call a Professional 

After performing all the above stated steps, if the air conditioner does not still perform as expected, it is recommended that you call in a professional. The ramifications of ignoring the situation can be serious for example failure of compressor, electrical issues, refrigerant leaks etc.
