You may need a gas top up if you notice any of the following:
Warm aircon
Your aircon is blowing warm or mildly cool air despite being set to the lowest temperature
Slow cooling
The room takes significantly longer to reach a comfortable temperature

Our Aircon Gas Top Up Process
We follow a structured, step-by-step process on every job.
01
Full System Inspection
Our technician inspects your indoor and outdoor units for visible damage, wear, or loose fittings before touching the refrigerant
02
Gas Level Check
We check your refrigerant levels using a gas gauge to determine if a top-up is needed and how much refrigerant is required.
03
Identify the Correct Gas Type
Different aircon models use different refrigerants. We check your unit’s specifications and top up with the correct gas (R22, R410A, or R32) in the right quantity.
04
Recharge and Test
We refill the refrigerant to the manufacturer’s recommended level and test the system for cooling performance, pressure, and proper operation before we leave.

Frequently Asked Questions
1. Why Does My Aircon Need a Gas Top Up?
Your air conditioner runs on a closed loop. The refrigerant inside does not get used up, it circulates continuously. So if your aircon is low on gas, it means refrigerant has escaped through a small crack, loose fitting, or worn-out component somewhere in the system.
This can happen to any unit. It is not always about age or brand. Wear and tear accumulates gradually even on well-maintained units.
The good news is that a gas top up usually restores your cooling effectively. For most units, the next top up is only needed after a year or more.
If your aircon loses gas again within a short period, that points to a more significant leak. At that point, a leak check, though time consuming and expensive, is worth considering to find and fix the source. Otherwise the costs add up over time.
At Jex Aircon, we will let you know honestly what we observe during the top up and advise whether further checks make sense for your unit.
2. How much does an aircon gas top up cost in Singapore?
Our gas top up prices start from $100 and depend on the size of your system. However, our aircon gas top up prices are the same regardless of whether your unit uses R22, R410A, or R32. View our full pricing above or WhatsApp us with your model number for a quick quote.
3. How do I know if my aircon needs a gas top up?
The most common signs are warm air blowing from the unit, a room that takes longer than usual to cool down, ice forming on the pipes or indoor unit, and unusually high electricity bills. A hissing sound is a strong indicator of an active gas leak.
4. Can I top up aircon gas myself?
No. Handling refrigerant requires specialised equipment, technical training, and licensing. Improper handling can damage your compressor, void your warranty, and pose a health and safety risk. Always use a qualified technician.
5. What aircon brands do you do gas top ups for?
We carry out gas top ups for all aircon brands available in Singapore, residential and commercial. If your unit cools a space, we can do gas top ups for it.
6. How long does a gas top up take?
A standard top up takes about 30 minutes per system.
7. How often does an aircon need a gas top up?
Under normal conditions, a well-maintained aircon should not need regular gas top ups. If your system is frequently losing gas, it means there is an ongoing significant leak that needs to be repaired, not just topped up repeatedly. We recommend a full inspection if you have needed more than one top up in the last 6 months.
8. Will a gas top up fix my aircon if it's not blowing cold?
Under normal conditions, a well-maintained aircon should not need regular gas top ups. If your system is frequently losing gas, it means there is an ongoing significant leak that needs to be repaired, not just topped up repeatedly. We recommend a full inspection if you have needed more than one top up in the last 6 months.
9. How often does an aircon need a gas top up?
Not always. Poor cooling can also be caused by a dirty evaporator coil, a blocked filter, or a faulty compressor. None of these require a gas top up. Our aircon technician will diagnose the actual cause before recommending any service.
10. What is the difference between R22, R410A, and R32?
R22 is an older refrigerant being phased out globally. R410A is the current standard in most Singapore homes. R32 is the newest generation, found in high-efficiency models released in the last few years. Using the wrong refrigerant will damage your unit, which is why we always verify the correct type before topping up.
11. Do you service all areas in Singapore?
Yes. We cover all residential and commercial areas across Singapore from the north to the south, HDB estates to landed properties and office buildings.
