Everything You Need To Know About Air Conditioner Coils


Air conditioners are a common appliance in many homes. In fact, most Singaporean homes have an air conditioning unit installed. We see aircon as an essential appliance to be comfortable year-round since the climate is hot here.


But why are aircon coils vital to the cooling process? We will explain things you need to know about air conditioner coils and why they need to be cleaned regularly if you want your aircon to run well and not break down prematurely.


What is an aircon coil?


A split air conditioner has two main units: one indoor and one outdoor unit.


The indoor unit houses an aircon coil, usually known as an evaporator coil or a fan coil. The evaporator coil’s job is to remove heat from indoor air so the blower fan can return cool, refreshing air to the home.


The outdoor unit also accommodates a condenser coil. Its job is to release captured heat from the indoor unit to the outside. That is why if you go near your outdoor unit, you will feel the heat coming from it.


The most common evaporator and condenser coils are made of copper tubing. Thin aluminium strips called fins are placed on the tubing. This helps transfer heating energy in and out of the home. There are other types of coils, such as all-aluminium coils or spine fin coils, but they are not as common.


When it comes to your air conditioning system, one of the most important things to keep in mind is the cleanliness of the coils. If the coils are dirty, it can impact the overall performance of your system and even cause damage in the long run. That’s why it’s essential to make sure you clean your air conditioner coils on a regular basis.


The advantages of regular aircon coil cleaning

Dirt, dust, debris, or other pollutants can build up on the coil surfaces due to the close spacing of the coil fins and the amount of usage it gets. This can block the flow of air and lower efficiency, causing your unit to work harder than necessary.


On the other hand, clean coils ensure:

  • Maintain comfort with to regulate humidity within the room
  • Normal operating temperatures because fans and compressors work correctly to achieve the desired indoor comfort due to no excess buildup of dirt and debris that can cause stress on the system
  • Save cooling costs; in fact, homeowners can save up to 10% on energy costs by simply cleaning their aircon regularly
  • Good cooling efficiency because coils are maintained to be in their optimal shape and size, creating the most cost-efficient air conditioning system for your home
  • Reduce wear and tear on your air conditioning system, therefore, prolonging its life


Besides, you can avoid hefty repair costs down the road. If dirt and debris accumulate on the coils, it can cause the system to work harder than necessary and eventually break down. So by keeping your coils clean, you can prevent any significant damage from occurring.


When do you need to clean your aircon coils?


You may be wondering: how often should aircon coils be cleaned?


This question is a little harder to answer as it depends on several factors, such as the type of aircon, the climate you live in, and how often you use your aircon.


However, a good rule of thumb is to clean your coils every 3-6 months.


If you live in a dusty or polluted environment, you may need to clean your coils more often. Similarly, if you use your aircon frequently, you will need to clean your coils more often.


How to clean AC coils?


When it comes to cleaning your air conditioner coils, there are a few methods you can try:

  • Compressed air duster

To clean the coils with a compressed air duster, you will need to remove the unit’s cover and locate the coils. Once you have found them, blast the dirt and debris off with compressed air. Make sure to be careful not to damage the fins on the coil.

  • Brush

This is an excellent way to clean the coils if there is only a little dirt. Make sure to be gentle with the fins as they can bend.


However, are you sure you can get the job done right?


That’s why you should schedule a professional aircon servicing instead of doing it yourself. Getting your air conditioner maintained and cleaned by trained and licensed professionals is the best way to ensure its longevity and efficiency. Moreover, you do not want to damage coil fins due to their delicate nature.
