When Should I Top Up My Aircon Gas?
Your aircon needs a gas top-up when the refrigerant level is low, causing weak cooling or warm air. Common signs include:
- Aircon blowing warm or less cold air.
- Ice or frost forming on the copper pipe.
- Hissing sound or gas leak detected by technician.
- Aircon takes longer than usual to cool the room.

How Do I Know If My Aircon Is Leaking Gas?
If your aircon gas is leaking, you may notice these symptoms:
- Aircon no longer cold or cooling unevenly.
- Ice forming on the copper pipe or evaporator coil.
- Hissing or bubbling noise from the indoor or outdoor unit.
- Frequent need for general servicing or repeated gas top-ups.
Our technicians perform leak detection and pressure tests before refilling to ensure the issue is resolved completely.
What Types of Gas Are Used for Aircon Top-Up in Singapore?
Most air conditioners in Singapore use one of the following refrigerants:
- R22 gas — older aircon models (being phased out).
- R410A gas — modern inverter aircons (Daikin, Mitsubishi, Panasonic).
- R32 gas — newer, eco-friendly refrigerant with higher efficiency.
Our aircon gas refill service uses only genuine, high-grade refrigerant suitable for your unit type.
Is It Safe to Top Up Gas Without Repairing the Leak?
No. Simply topping up gas without repairing the leak is a temporary fix and may cause further damage.
- Gas will leak again within days or weeks.
- Compressor may overheat or fail due to insufficient pressure.
- Always request a leak test or overhaul if frequent top-ups are required.
What Happens If My Aircon Gas Is Too Low?
Low refrigerant gas affects both performance and safety:
- Reduced cooling efficiency and longer run time.
- Higher electricity consumption and power bills.
- Risk of compressor overheating or failure.
- A professional gas refill service restores proper pressure and cooling balance.
How Long Does an Aircon Gas Top-Up Take?
The entire process usually takes 30 to 45 minutes per unit, including inspection and testing.
- 10–15 mins — Leak inspection and pressure test
- 10–20 mins — Gas refilling (depends on type and system)
- 10 mins — Cooling test and final verification
