When do you need Aircon Piping Installation or Reinstallation?



Firstly, if you trust your Aircon technicians, there won’t be a need to read this article. This is because they will generally provide you with quality Aircon installation materials. Therefore, it will be less likely for the aircon piping to wear out and require a replacement. Nevertheless, there are times when you need to get your Aircon piping reinstalled such as if there are condensation issues with your Aircon Piping or trunking for example. That is because most of the older Aircon models used in the past are made of outdated materials. Whereas the current inverter Aircon models use upgraded installation materials. The air pressure from an inverter Aircon unit is higher. Hence, using outdated aircon installation materials will cause condensation problems.


AIRCON materials needed for Aircon Piping installation


Armaflex Insulation

1/2 inch vs 3/8 inch


This is pretty much the most important Aircon material you need to take note of. It is advisable to use thicker insulation for installation of air-conditioners at home. The thicker the insulation, the more likely it is to absorb condensation from the water pipes. Besides, it is extremely costly to re-run Aircon piping. That is due to the cost of the materials and the labor involved. Therefore you want to prevent this by installing thicker, higher quality aircon piping.


For insulation, there is a general term being used by Air-conditioning installers in Singapore, namely “upgraded materials”. For upgraded materials, the insulation used is ½ Inch Armaflex insulation; whereas normal materials will be using 3/8 inch Armaflex insulation. If you take a look at the picture above, you can see the difference in size of the insulation. The thicker insulation will be having much better absorption ability.


Other than thickness of the insulation, another property you might be concerned of is the class of insulation. You might have seen the term “ ½ inch Armaflex class 1” or “1/2 inch Armaflex class 0”. The class refers to the fire-resistant property of this insulation. Honestly, it doesn’t make any difference to the quality of the materials for your Aircon installation. So it is not something you will need to pay much attention to.


Copper pipes

If there’s any issue of gas leaking, you will either have to change your entire condensing unit or re-install your Aircon piping. As mentioned earlier, the cost of re-running your Aircon piping installation is extremely costly. The cost of a Aircon Pressure Test which is to find out location of the gas leak is also pretty expensive. If you would like to know more about Aircon gas leaking, click on the link below:

The upgraded copper pipe used will be SWG22 copper pipe or “G22 copper pipe” for short. The normal, outdated material used is G23 copper pipe. The G22 copper pipe is thicker, hence it is less likely to have gas leak. This is because it is be better able to withstand pressure of the refrigerant.


Water pipe

Aircon Piping Installation involves the usage of water pipes. These water pipes used have no distinctive brands. Generally, the only 2 sizes used for HDB are 13mm/16mm. The bigger the better, as water will be better able to flow through it, without causing drainage issue. 


Cable / Electrical wire



Aircon Piping Installation also involves the usage of electrical wires. The ones used to connect your fan coil unit from your compressor is usually three core. The term 3C70 stands for 3 core wire with 70 strands of wire in each cable. In general, you should go for the Singapore brands (for e.g Sigma cable / keystone cable), and use the ones that are 3C70.


Aircon Trunking / Casing



Aircon trunking or casing as shown in the picture above is used to cover or hide all the relevant Aircon installation materials. The brand or type of trunking does not matter. The type of trunking that will be used depends on which brand the Aircon installer is familiar with. Installation materials are concealed in landed property ceiling. Therefore, you will not be able to see it during landed property aircon installation. Aircon Trunking is usually more visible in HDB.



In conclusion, it is imperative to use good Air-conditioning materials for your Aircon Piping Installation. This is to prevent serious issues from arising in the future, such as condensation problem or electrical tripping due to broken wire.
