Aircon Gas Leak

Neglecting your aircon’s maintenance schedule will cause a bad leak eventually. The wear and tear damage affecting an air-conditioner might cause a hole in the gas storage causing a leak that will deplete your storage.

Tubes can also get damaged and will cause a gas leak because this is where your refrigerant will pass through. Improperly installed air-conditioning units will surely cause a gas leak. This might be because there was a bad piping job that will make the gas flow out of the air-conditioner. Corrosion on the pipes and other tubes will let the gas leak as well. This type of damage is due to the chemicals leaking out causing the metal pipes to rust.

The Type Of Aircon Gas And Their Distinct Differences

A good place to start this little guide is with the type of refrigerant on offer. There are two available on the market, namely R22 and R410a.

At Coolbest Aircon, you can get both, but you should also know why there are two options. For several years now, R22 was used as the refrigerant industry standard. And yes, it has done its job up until now. But recently, R410a was introduced with the specific aim to push out R22.

This is because:

  • R22 is less efficient, given that it can't absorb and release heat/cold like R410a 
  • R22 is not as environmentally friendly as R410a
  • R22 is getting more expensive as it gets phased out

When it comes down to it, R410a is the logical option if you want your aircon to run as efficiently and environmentally friendly as possible.

But this is your choice to make, and as mentioned earlier, you can get both options from us. We just feel it's important for our clients to have total transparency regarding the gas being used for the top-up. And if you feel more comfortable with R22, we can handle it easily.

Why Is It Important To do Aircon Top Up Gas?

There are several reasons why you want to stay on top of the gas levels, and they include:

  • Maintaining energy efficiency levels
  • Topping up will fix leaks in the Freon
  • Without gas, the aircon won't function like it should

There's a reason why professionals make aircon gas top-ups part of the regular maintenance plan, and it speaks directly to the efficiency and energy consumption of the aircon.

The Step By Step Process To Top Up Gas

Even though it is not impossible for individuals to handle the gas top up by themselves, it is not a simple or easy task. In fact, it can get quite complicated if you don't know exactly what you are doing. To give you some idea of what needs to happen, here is a step by step guide.

  1. Establish that there is refrigerant within the system.
  2. Clean all the debris that can possibly block the condensing coils or influence the operation of the compressor.
  3. Tap on the refrigerant can then thread the tapping valve securely onto the can with the valve closed.
  4. At this point, the valve can be opened, causing a distinct sound of gas filling in.
  5. Now, you need to locate the charging point with low pressure, followed by more power from the engine. You should also switch on the aircon at high fan or cool.
  6. Allow the gas to dispense completely.
  7. Close the valve and disconnect the hose.
  8. Test whether the aircon is working properly. 

Naturally, this is just a quick explanation of what is supposed to happen, but when you hire professionals like us, it's not something you have to worry about. All you have to worry about is enjoying your aircon at its top level of functionality.

Checking for Gas Leaks

A gas leak can’t be addressed by topping up your AC with new refrigerant gas without addressing the source of the problem. If there is a leak, you can do simple tests to check if your gas is leaking and where the leak is found.

Gas Leak detectors

There are electronic tools available that can detect a gas leak from your air-conditioning unit. You use this tool on the parts of your air-conditioner where refrigerant passes through. The device will see if there is an unusual residue of gas on these parts.

You need to touch the device on the part to detect leaks. Make sure you expose the parts that need to be checked for leaks. This is an accurate method and you should position it properly to detect the problem.

Nitrogen Lead Detection

Using this method, you should remove the compressed nitrogen gas inside the air-conditioner. A leak will produce sounds that are noticeable. Trace the sound and where it comes from to find the part that’s leaking the gas.

You can also use a pressure gauge to see if the pressure is low. There is also a technique where you use soapy water and run it down the refrigerant. A leak will produce bubbles, and this is also the sign where the damage is found.

Dye tests

 Buying an ultraviolet dye for your system is also an effective method to detect a leak. You allow the dye to mix with the lubricant running through your air-conditioning. If there is a leak, the dye will cause a stain on the part where the leak is found.
