Factors That Can Affect Your Aircon Efficiency

A well-cooled room in the hot days of summer is one of the essential comforts of our lives. In the highly-urbanized countries of the world like Singapore, the number of aircon units continue to increase.

If properly maintained, an air-conditioning system can guarantee efficient functionality and lesser faults through the years.

However, if you do not care about certain factors, your aircon will likely start showing some problems in functionality or will not be able to cool a room as efficiently as it should.

There are certain factors which can cause your air conditioner to become faulty. These are described below:

Climate

A hot and humid climate like that of Singapore calls for extra care and maintenance to guarantee good aircon efficiency.

This also means that you would require more air-conditioning units in a house and they would be running for longer periods of time to ensure a cool and comfortable temperature in your room.

When aircons run for long durations, they are more prone to accumulating dust especially in the outer units.

To keep the inside temperature low, the air-conditioner has to work constantly against the high temperature outside. This means that it will get affected by wear and tear faster as compared to an aircon which is installed in a relatively less hotter climate.

Only with regular maintenance will your aircon be able to run smoothly and effectively year after year.

Insulation

The kind of insulation your room provides also affects the efficiency of your aircon. If your room is able to resist heat, it will result in a better efficiency by the aircon as well. Good insulation helps the cold air to remain inside while still resisting the outside warm and summer air.

Using weather-resistant materials for doors, windows, and vents also results in increasing the aircon’s efficiency. The number of doors, windows, and vents also affect the way cold air remains inside a room.

The more outlets there are in a room, the more there will be chances of cold air loss which will then have to be offset by your aircon.

Room Size

The size of a room also affects the efficiency of the aircon. A bigger room will require a bigger capacity air-conditioning unit otherwise it will not function properly.

If a low-capacity aircon is used in a big room, it will cause the aircon to work much harder in order to maintain the temperature. This will cause more wear and tear to the aircon in less amount of time resulting in more malfunctions and a drop in its efficiency.

Poor Airflow

If your aircon is facing issues of poor airflow, it might not work properly. Poor airflow can be defined as some blockage which does not allow the aircon to breathe properly.

This can be due to a clogged air filter or a blocked condenser unit. In the presence of such a blockage, the aircon has to work harder to keep the room cold.

This not only further aggravates the problem and cause other malfunctions, but it also consumes a lot of energy. This is then manifested in the form of higher utility bills.

A good aircon servicing service should be able to help increase the airflow of the aircon.

Clogged coils

Coils of the condenser are responsible for transferring the heat of the room outside while the air con continues to bring cold air inside. If these coils get clogged or a layer of dust forms on it, it affects the condenser’s efficiency.

It will not be able to take the hot air of the room outside as efficiently as it could so it will have to work much harder. This will again cause other parts of the air-conditioning to malfunction which can even lead to a system failure. Keeping the condenser coils clean and unclogged are essential to ensure the smooth functioning of your aircon.

Another factor relating to the condenser coils which can affect your aircon efficiency is frozen coils. The condenser coils need warm air flowing around them to be able to function properly.

If the airflow is restricted through a clogged air filter, this can cause the coil to become cold resulting in the formation of a layer of ice on the coils. This will stop the aircon from throwing in any cool air inside the room.

In such cases you may need an aircon chemical cleaning or overhaul service to clean out the stubborn stains and blogs.

Duct Issues

If there is any leak, crack, or gaps in the ductwork of the aircon, it will negatively affect its efficiency. The gaps will not only prevent the cold air from reaching all parts of the room, but it will also allow hot air from the gaps to be mixed with the cold air.

This will cause the aircon to work harder to maintain its efficiency resulting in higher energy bills. This will cause the efficiency of the aircon to drop. The gaps will also result in more dirt buildup inside the ducts further decreasing the efficiency. These gaps and leaks in the ductwork may be caused by poor installation or rodents.

A chemical cleaning or overhaul can help in removing the excess dirt and making the airflow more smooth.

Fan Issues

There are two fans inside your aircon system. One fan in the inner unit is responsible for blowing the cool air over the evaporator coil and into the room whereas the other fan in the outer unit is responsible for throwing the hot air from the room through the condenser coil and outside the house.

If any of these fans stop working either due to a worn-out belt, lack of lubrication, or dust buildup, it will affect the aircon’s efficiency. A faulty fan can result in poor airflow which will take out the toll on the condenser. It can even lead to a system failure if not addressed.

Thermostat Issues

Issues with the wrong setting of the thermostat can also affect the aircon’s efficiency in the long run. In the case of older units with a manual thermostat, it could easily malfunction.

You could apparently be setting the thermostat at one temperature whereas it might not be getting set at that temperature because of the malfunction.

In the case of modern digital thermostat settings, setting it on a lower value will push the aircon to its limits where its compressor might not be able to rest in between. This can affect the compressor and its efficiency.

Setting the thermostat to a reasonable temperature will not only allow the aircon to continue with its efficiency for longer periods but also help in conserving energy and bills.

Drain Issues

An air-conditioner works by expelling the moisture that it collects from the room and throwing it outside through a drain pipe. If this pipe does not drain properly, it can result in water leaking from the front unit.

If the pipe has leaks or cracks near or inside the wall, it can damage not only the walls but also the inner parts of the air conditioner. This can even result in the growth of mold which can completely rot the pipes inside the framework of the aircon.

The only solution in such a case would be to completely change the inner pipes which is a long and troublesome process. These are some of the factors that can cause the efficiency of your aircon to decrease. By having regular maintenance checks and aircon servicing, you can ensure that your AC continues to work efficiently y
