What Is Aircon Gas Top-up?
An aircon gas top-up is a refrigerant recharge that restores your air conditioner’s cooling performance. Over time, refrigerant levels drop due to minor leaks or natural wear in the system, causing your AC to blow warm air, run longer cycles, and consume more electricity.
There are two main types of refrigerant gas used in Singapore homes:
- –R22: Used in older units (pre-2015). Priced at $120/unit. Being phased out globally due to ozone impact.
- –R410A/R32: Used in modern units (2015 onward). Priced at $130/unit. Eco-friendly with zero ozone depletion. The $10 difference reflects higher environmental manufacturing standards.
- –How to check: Look at the sticker on your outdoor condenser unit, it lists the refrigerant type (R22, R410A, or R32).

Everything You Should Know About Aircon Gas Top-up in Singapore
Have you ever wondered how your air conditioner is able to cool the room? Most air conditioners on the market require a gas called Freon to function. This gas is what helps the air conditioner to transfer heat, and without it, your air conditioner will not work properly.
If you notice that your air conditioner is not cooling as well as it used to, or if it seems to be making strange noises, then it may be time for an aircon gas top up. Keep reading to learn everything you need to know about an aircon gas top up.
What is Aircon Gas?
Aircon gas is a type of refrigerant that is used in air conditioners. It helps to transfer heat from the inside of your home to the outside, and without it, your air conditioner will not work properly.
How Does Aircon Gas Work?
Aircon gas works by transferring heat from the inside of your home to the outside. The aircon gas is compressed, and this creates a cooling effect. The aircon gas then expands, and this helps to cool the air inside your home.
The ability to cool your room quickly and efficiently is determined by the aircon gas. If there is not enough aircon gas in your air conditioner, then it will not be able to transfer heat as effectively, and your air conditioner will not work as well. If you’re experiencing issues like the aircon compressor not working or your aircon is not cold, these could be signs that your system needs a gas top-up or other maintenance.
Why Do You Need a Gas Top-Up?
Your air conditioner operates as a closed system, meaning refrigerant should circulate continuously without depleting. Unlike fuel in a car, refrigerant doesn’t get “used up” during normal operation. If your aircon needs a gas top-up, it indicates there’s a leak somewhere in the system that must be addressed.
Common signs you may need a refrigerant top-up include your aircon blowing warm air instead of cold, taking longer to cool the room, ice forming on the refrigerant pipes, or unusually high electricity bills. You might also hear hissing sounds, which indicate an active leak.
Important: Simply topping up the gas without fixing the leak is a temporary solution that wastes money. The refrigerant will leak out again, and you’ll face the same problem.
A professional technician should always locate and repair the leak first before adding new refrigerant. This ensures your aircon works efficiently and prevents repeated top-ups that damage both your wallet and the environment.
Type of Aircon Gases
There are two main types of aircon gases: R-22 and R-410A. R-22 is the most common type of aircon gas, and it is typically used in older air conditioners. However, the use of R-22 is gradually on the decline because it is harmful to the environment. R-410A is the newer type of aircon gas, and it does not damage the ozone layer.
Aircon Gas Top Up
Here’s some frequently asked questions about aircon gas top ups:
Does an Aircon Need to Top Up Aircon Gas?
Yes, air conditioners need to be topped up with aircon gas every so often. Over time, the aircon gas will leak out of your air conditioner, and this can cause your air conditioner to work less efficiently. If you notice that your air conditioner is not cooling as well as it used to, then it may be time for an aircon gas top up. To better understand the signs and causes of this issue, you might want to explore more about aircon gas leaks and how to prevent them. Additionally, if you’re experiencing an aircon leaking water, this could be a related issue that also needs attention.
Type of Gas Available for Top Up
The type of aircon gas that you will need to use for your air conditioner will depend on the type of air conditioner that you have. If you have an older air conditioner, then you will need to use R-22 aircon gas. However, if you have a newer air conditioner, then you can use either R-22 or R-410A aircon gas. Both are available for top up.
How to Top Up Aircon Gas
If you need to top up your aircon’s gas, then you can do so yourself or you can hire a professional. If you decide to do it yourself, then you will need to purchase an aircon gas top up kit. These kits are available at most hardware stores. Once you have the kit, follow the instructions carefully to avoid damaging your air conditioner.
Hiring Professional Help for Aircon Gas Top Up
If you have any questions about aircon gas top up or are looking for the safest option to top up your aircon gas, then please contact a local air conditioning specialist. They will be able to help you choose the right aircon gas for your air conditioner and they can also provide you with aircon gas top up services.
Professional Aircon Gas Top Up Rates
The cost of aircon gas top up will vary depending on the type of air conditioner that you have and the amount of aircon gas that you need. Generally, you can expect to pay between $100 and $200 for aircon gas top up.
If you have any questions about aircon gas top up or if you would like to learn more about air conditioners, then please contact a local aircon servicing. They will be able to help you choose the right aircon gas for your air conditioner and they can also provide you with aircon gas top up services.
How Often Should I Top Up Aircon Gas?
You should typically top up aircon gas once every two years. However, before that, if you notice that your air conditioner is not cooling as well as it used to, then it may be time for an aircon gas top up.
What Happens During a Gas Top-Up?
An aircon gas top-up involves several important steps to ensure your system works properly and efficiently. First, the technician will inspect your aircon and check the system pressure using specialised gauges to confirm that low refrigerant is actually the issue.
Next comes the crucial step: leak detection. Using methods like UV dye testing or electronic leak detectors, the technician locates where the refrigerant is escaping. Once the leak is found, it must be repaired before any gas is added — this might involve tightening connections, replacing damaged pipes, or fixing faulty valves. Simply topping up without fixing the leak is a waste of money as the problem will recur.
After the repair is completed, the technician evacuates any remaining old refrigerant and moisture from the system using a vacuum pump to prevent contamination. Then, the correct type and amount of refrigerant is added according to your aircon’s manufacturer specifications.
Finally, the system is tested to ensure proper cooling, pressure readings are verified, and a final leak check is performed. A reputable technician should provide documentation showing the type of refrigerant used and the amount added.
This entire process typically takes 1–2 hours, depending on the complexity of the leak and repair needed.
Gas Top-up Care for Every Season
Singapore’s tropical climate means your AC works overtime, and that drains refrigerant faster
Monsoon & Rainy Season
Heavy rain · High humidity · Dec – May- High humidity forces AC to dehumidify harder, increasing refrigerant demand
- Check for ice buildup on evaporator coils after prolonged rainy spells
Haze & Poor Air Quality Season
High PSI · Dust & smoke · Jun – Oct- Closed windows mean AC runs 24/7 during haze, accelerating refrigerant use
- Dust buildup on coils reduces efficiency; pair gas top-up with a general service
Hot Weather & Peak Usage
Tropical heat · Year-round · Heavy use- Peak heat months stress your compressor; low gas levels can cause permanent damage
- Schedule a gas level check before the hottest months to avoid mid-summer breakdowns

Everything you need to know before booking an aircon gas top-up.
R22 is an older refrigerant used in aircon units manufactured before 2015. It is being phased out globally due to its ozone-depleting properties. R410A and R32 are newer, eco-friendly refrigerants used in modern systems from 2015 onward. They have zero ozone depletion potential and are more energy-efficient.
The two gas types are not interchangeable, using the wrong refrigerant will damage your compressor. Check the sticker on your outdoor unit to confirm which gas your system uses.
R22 gas top-up is $120 per unit and R410A/R32 gas top-up is $130 per unit. The $10 difference reflects the higher production cost of newer eco-friendly refrigerants. You can book for 1 to 8 AC units per session. A service fee of $3.90–$4.35 also applies per booking.
Check the specification sticker on your outdoor condenser unit. It will clearly state the refrigerant type as R22, R410A, or R32. If your unit was installed before 2015, it most likely uses R22. Units from 2015 onward typically use R410A or R32. If you are still unsure, book our $60 diagnostic service and our technician will confirm on-site.
Your aircon needs a gas top-up when refrigerant levels have dropped below the manufacturer’s recommended level. This typically happens due to minor leaks in the sealed system. A properly maintained unit should not need frequent top-ups, if you find yourself recharging every few months, there is likely a leak that needs repair first.
Common signs include: your AC blows warm or lukewarm air instead of cold, ice forming on the evaporator coil or copper pipes, the unit running constantly without reaching the set temperature, a sudden increase in electricity bills, and hissing or bubbling sounds near the indoor or outdoor unit. If you notice any of these, book a gas top-up or diagnostic service.
No, there is no minimum order value. You can book a gas top-up for as few as 1 AC unit. We support up to 8 units per booking session. The pricing is straightforward: $120 per unit for R22 or $130 per unit for R410A/R32, with no volume discounts or hidden fees.
A small service fee of $3.90 to $4.35 applies per booking. This covers platform and scheduling costs. The fee is clearly shown during checkout before you confirm your booking, no hidden charges.
Booking takes under 60 seconds. Enter your postal code on our website or app, select “Gas Top-up” and your gas type (R22 or R410A/R32), choose the number of units (1–8), pick your preferred date and time, and confirm. Our certified technician will arrive on schedule with the correct refrigerant and professional equipment. Payment is only deducted after the service is completed.
