What is refrigerant gas?
Refrigerant is found in a gaseous or fluid state. It absorbs heat readily from the surrounding environment and provides air-conditioning or refrigeration when it is combined and used with other components like evaporators and compressors.
How Does A Refrigerant Work in Air Conditioning?
Refrigerants are the reason why freezing technology, refrigeration, and air-conditioning exists.
Air conditioner units and systems house refrigerant in the copper coils. When the refrigerant starts absorbing heat from the air, it changes from a low-pressure gas into a high-pressure liquid. The components in the air conditioner force the refrigerant outside and from here the fan in the unit will blow the heated air over the copper coils where it is then exhausted outside.
The refrigerant then starts to cool down where it converts back into a gas. Another fan that is situated indoors will blow air across the cold coils. This distributes the cooled air through the building or the home. This cycle then repeats.
The Type of Aircon Gases
There are several different types of gas that are used in air conditioning units. The two main ones that are seen on the market today are R22, and R410.
R22 is also known as Freon, it is a gas that was introduced to the markets decades ago as an environmentally friendly alternative to the original CFCs. While R22 is indeed more environmentally friendly than other gases, it is far from environmentally friendly, and the Montreal Agreement saw many countries agree to phase out the use of R22 gas. Because of this phase out, most new air conditioning units run other gases, and it can be quite hard to purchase R22 to top up old units, because so few countries make it now. If you have a unit that is powered by R22, you should be proactive about servicing it to ensure that it does not leak. Regular maintenance will keep your unit in good shape, protect the environment, and protect your pocket book from the potential expense of needing to do a full R22 recharge
R410A is a new type of refrigerant that has all but replaced R22 in most parts of the world. R410 is more environmentally friendly, and more efficient, so it is a good choice for a replacement. IT is better at both releasing heat and absorbing it, and it is less damaging to the ozone layer. It does, however, require more durable parts in the air conditioning unit itself, which means that it will not work in older R22 units. If you have a newer unit, though, there is a very high chance that it uses R410A.
Does An Aircon Need To Top Up Aircon Gas?
In the ideal scenario, an aircon gas top-up becomes necessary when the levels have dropped by 10%. A gas level drop of 10% can result in a 20% increase when it comes to the electricity that you are consuming.
How Often Should You Be Topping Up Your Aircon Gas?
In normal cases, you should be topping up your aircon gas every 1 to 3 years. However, some people prefer to play it safe and have their units topped up every 6 months. If you have started to notice that your air conditioner is not operating as efficiently as it used to, it may become necessary to top up the aircon gas sooner, since your refrigerant storage might be leaking caused by wear-and-tear or damage.
How to Top Up Aircon Gas?
Really, the term ‘recharging’ for air conditioning units does not make a lot of sense. The air conditioning unit is not a battery, rather, it is a large container. The refrigerant pulls heat out of the air, and then transports that heat through the system. Topping up the refrigerant simply means refilling the refrigerant so there is enough in the system to get the job done.
The process will depend on the type of system, usually, the air conditioning technician will do the following:
- Check air filters, pipes and other parts.
- Check the compressor
- Check the fluid levels of the refrigerant
- Confirm the type of refrigerant, and the desired level for the system in question
If there is an issue with the refrigerant levels in the unit, then the technician will take some time to identify why the refrigerant levels are low. If there is a leak, then it could be worthwhile to replace the leaking components and do a full recharge.
If, however, the leak is very small then it may make more sense to just top up the gases in the unit during your regular maintenance visit, and consider other options at a later date.

FAQs About Aircon Gas
Can I Top Up My Aircon Gas Myself?
It is possible to purchase an air-con gas kit if you are interested in attempting this job yourself. However, most experts won't advise it.
These kits cost almost the same to pay a trained technician to do this job. If something does go wrong, you may end up having to pay out much more for a costly repair bill.
Aircon technicians also know how to properly check for problems or leaks with your air-con system. There are also safety factors that need to be taken into consideration. For example, refrigerant gas can result in very painful and hazardous freeze burns should it accidentally come into contact with your eyes or skin.
What Will Happen If An AC Runs Without Gas?
When the refrigerant level is too low, your AC will no longer be able to absorb hot air in your home. This usually happens when the air that blows out of your vents starts to feel warmer or even hotter than usual.
In certain cases, the air blowing from your vents will also start to decrease.
An AC unit that does not have enough refrigerant could also freeze over, where it turns into one large block of ice. This layer of ice will also stop the airflow, which slows down the air that is supposed to be coming out of your vents.
Can Aircon Gas Run Out?
Aircon gas is not supposed to run out, but external actions or a gas leak can reduce the amount of gas in the system. The refrigerant can deplete when the gas storage and pipes are damaged, or when repair work has reduced the refrigerant levels.
Should I Fill My Air-Con Gas Every Year?
No, it is not always necessary to top up your AC gas every year. In the ideal world, air conditioners should never run out of refrigerant. Aircon gas is not like the gas that a car uses.
This means that you will only need to top the refrigerant up when a leak occurs. The only way to determine whether there is a leak in the system is when an AC technician measures the levels.
