With Singapore’s hot and humid environment, air conditioners are indeed a necessity. They help cool the air, control your room’s humidity levels, and make the room more comfortable to be in. Hence, if your aircon does not blow cold air, it will lead to an uncomfortable night.
Then, especially with COVID-19, the quality of your air conditioning has now become significantly more important. More people are working from home, and now that certain outdoor activities are restricted—or require the use of a mask—people are spending more time at home.
If you wish to be cool and comfortable at home despite the heat, then it would make sense to ensure that your air conditioner is functioning correctly.
Air conditioners contain a filter through which air passes through. The inclusion of this feature is helpful both to the user as well as the air conditioner itself. Even if the air looks clean, it often contains dust and various other unwanted particles. The air conditioner’s filter traps these particles, cleaning the air for a more comfortable user experience.
Additionally, the filter is critical to the proper functioning of the air conditioner. Just like humans, air conditioners do not perform well when the air that passes through them is dusty and polluted.
However, filters need maintenance, too, such as from regular aircon servicing.
This is because the particles that they trap have to go somewhere. Over time, as the filter operates, the trapped particles build up on the filter surface. For example, dust can accumulate to such an extent that the gaps through which air can flow through the filter are significantly lessened.
Thus, the air conditioner might not be able to blow out much air at all. An air conditioner cools the room by taking in warm air and blowing out cold air. In other words, a diminished airflow will lead to the trouble of aircon does not blow cold air.
Have you ever set the air conditioner to 25 degrees celsius, but it certainly did not feel like the air in the room was cooled to 25 degrees celsius?
This could be due to a malfunctioning thermostat. The thermostat discerns the current air temperature in the room and communicates this information to the air conditioner.
For example, consider a situation where the air temperature of the room’s air, as measured by the thermostat, is higher than the user’s temperature. Then, the air conditioner would know that it has to perform additional cooling to reduce the temperature to the desired level.
Thus, if the thermostat is not functioning or is sensing the temperature inaccurately, the room will not be cooled to the user’s desired level.
A number of reasons may cause such malfunctioning. The first possible reason is that a break in the electrical circuit. A thermostat requires electricity to function. If not present, the thermostat will be unable to sense the surrounding air’s temperature. Second, certain adverse physical conditions may be present that would impact the usual functioning of the thermostat. If there is a lot of dust inside the air conditioner and on the thermostat, this can skew its reading and affect the air conditioner’s cooling level.
A compressor is crucial for the air conditioner’s cooling capabilities. The compressor affects the flow of the refrigerant inside the air conditioner. The refrigerant is a substance that facilitates the transfer of heat. The refrigerant can absorb and release heat, which does so at various stages of the air conditioner’s function. The air in the room is cooled when the room’s air blows over the cold refrigerant and is made cold too.
The compressor enables the refrigerant to serve this function as, after all, the compressor drives the refrigerant’s movement. This is performed as follows. The compressor can control pressure, so it creates pressure differentials—for example, one area having higher pressure and another having lower pressure—so the refrigerant in the higher-pressure area is made to flow to the lower pressure area.
When an air conditioner malfunctions, a problem with the compressor is one of the most common reasons. Its huge role in the cooling process means that the improper function of the compressor may significantly diminish the cooling capabilities of the air conditioner.
As above, an air conditioner cools a room when the warm air of the room blows over cold refrigerant, which makes the air cooler. If there is a leak within the air conditioner’s systems, refrigerant (which is, at some stages, a gas) may escape, and therefore there may not be any refrigerant left in the air conditioner.
If this happens, there would be no cold refrigerant for the warm air of the room to transfer heat to. If your air conditioner has insufficient refrigerant, it would not be performing to its full potential. In this case, it would be necessary to investigate where the leak is, resolve the leak, and add a new refrigerant to the air conditioner. This would require a professional’s help, as handling refrigerant on your own may be dangerous.
Some of these problems, if they are minor, can be solved on your own. However, many of them require a professional’s help. The repairing of specific components is a complex affair.
Furthermore, there are certain risks involved in air conditioning maintenance. For example, the refrigerant may be dangerous to touch or inhale.
