    • Resupplying or replacement of the aircon's chemical coolant to enable it to emit the right amount of cool air

    • The final measurement of your aircon unit's temperature output after the entire treatment has been done to ensure if the status improved

    What Are The Gas Types Used In Aircon Top-Up?

    This service requires different types of gas depending on the type of your unit. Every kind of gas is made from a particular chemical and they also vary when it comes to their effects. We will determine which classification of gas is suitable for the type of aircon unit that you have.


    The R-410 gas and its R-410A variants are considered the newest types of coolants used in aircon units. This substance has a high cooling efficiency but, unlike some of its predecessors, it does not have any negative impact on the environment. This gas type is environmental-friendly and also much affordable because of the amount of gas required and its usage reduced. We highly recommend this type of gas because of its benefits. However, while this is easy to handle, we advise seeking assistance from professional aircon specialists to supply this.

    R22 gas is one of the old types of gases and is known to be a typical Freon gas. It is still commonly used in old units as a coolant in the compressor. It will be depending on your aircon unit but usually, this is the gas type that it will need for a full top-up service. However, this is also a type of hydrofluorocarbon that can potentially damage the world's ozone layer. It is beginning to be phased out, even in Singapore, since the industry is transitioning towards more environmental-alternatives. That is why we recommend you to use a different type of coolant if it is compatible with your HVAC unit.


    This gas is a difluoromethane that is commonly used in the Freon brand. This mixture has been developed and designed already long ago and it demonstrates relatively high efficiency in aircon cooling which is why many use it as a gas in aircon systems in Singapore. This gas is mostly affiliated with Daikin models, which we are experts in handling its gas top-up requirements. s.

    The R134 is a widely used gas but it requires much higher pressure and is increasingly difficult to handle. This refrigerant type is being applied to older aircon models but it requires the handling of more experienced aircon maintenance contractors. Fortunately, SOServices has experienced and knowledgeable technicians to handle this type of gas.

    Why Is An Aircon Gas Top-Up Important?

    Before you assume that this type of servicing is expensive and unnecessary, here are some factors you should know when it comes to the importance of aircon gas top-up:


    To Maintain Aircon Functionality

    Aircon units bring in the cool air that provides people with comfort. If it has problems producing the right kind and amount of cooling air, it would be a waste of electricity and a cause of discomfort in your home or workplace. The top-up gas process involves fixing the refrigerant of your aircon unit. The refrigerant is used to absorb the heat that may be present in your house and get rids of it by releasing it outside. If your aircon's refrigerant level is not good, then do not expect your aircon to function properly. A regular gas top-up will ensure the consistent optimal cooling ability of your aircon unit.


    To Prevent Damage To Your Aircon

    When the refrigerant tank's health level is not maintained properly, this will cause a certain leak in the system caused by the differences of pressure in the tanks and the atmosphere. This kind of damage can be avoided by regularly checking and having top-up gas done on your aircon's gas tanks. An aircon gas top-up is very important when it comes to the proper maintenance of your aircon unit because if it encounters any problems, the repairs for that will be much more costly for you. Prevention is always better than cure.


    To Increase Aircon Efficiency

    As mentioned above, an aircon's functionality highly depends on its refrigerant. If the refrigerant is not maintained well, the aircon is having a difficult time utilizing it without causing any damage to the system. The top-up gas process will help your unit keep its refrigerant be at a healthy level which means more efficient cooling for you. This will save you from spending too much on repairs and excessive energy consumption.

    How Is The Aircon Gas Top-Up Being Done?

    Step 1: Checking The Pressure

    SOServices aircon technicians start the process by using an instrument—a measuring gauge—to check the pressure inside your air conditioning unit. If it shows that the pressure inside your aircon is low, then it’s an indicative sign that there is an insufficient amount of refrigerant inside the unit. Another sign that there isn’t enough refrigerant inside the aircon unit is if it’s not functioning as well as it used to. Without a healthy refrigerant level, an air conditioning unit is unable to do most of the work.

    Step 2: Charging Up The Gas Tank

    As a trusted professional aircon servicing company in Singapore, we always start this step by storing the gas in a specialized gas tank to prevent leaks and damage to the refrigerant. The refrigerant should be really taken care of since the optimal cooling ability of the aircon unit relies on it. After the refrigerant is pumped into the gas tank, our experienced aircon technicians will again measure the pressure inside the air conditioner to ensure if the refrigerant has been inserted into the aircon unit successfully.

    Step 3: Final Checks For Maintenance

    After refilling the gas, the last thing to do is to do some final checking of your aircon unit. This is to completely make sure that no other damages or complications have been overlooked. SOServices’ aircon technicians pride themselves on thorough maintenance checks after a gas top-up service. If we happen to find any after a careful inspection, we will recommend a solution and fix it on the spot for you. This will ensure that the aircon has no other faults that could cause further damage–both to your homes, your environment, and to your wallet.

    How Long Does Aircon Gas Last?

    According to most aircon brands, aircon gas has an average lifespan of 10-15 years, depending on its maintenance and usage. When you take care of and maintain your air conditioner well, its gas can last for even up to 2 decades. However, if you do not have it regularly inspected, cleaned, and refilled with a proper chemical coolant by an experienced aircon servicing company like SOServices, then expect it to last for only 5 to 10 years.

    How Much Does Aircon Gas Top-Up Cost?

    Here at SOServices, we offer cost-effective services for our valued customers. The rate for our aircon gas top-up would be eighty dollars (80$) per unit. If you have any further questions, do not hesitate to contact us.
