Gas Top-Up in Singapore
Refill refrigerant gas (R22, R32, or R410A) when your aircon is not cooling effectively due to low gas levels.
Frequently Asked Questions
- How much does an aircon gas top-up cost in Singapore?
- Aircon gas top-up in Singapore costs S$80–S$220 per unit depending on the refrigerant type. R32 gas is the cheapest (around S$54–S$120 per top-up), R410A costs S$97–S$200, and the older R22 gas costs S$85–S$200 per top-up. Prices vary by the amount of gas needed.
- How do I know if my aircon needs a gas top-up?
- Signs your aircon needs a gas top-up include: the unit blows air but it is not cold, the outdoor unit's copper pipes are frosting over, the aircon takes much longer than usual to cool the room, or the unit trips the circuit breaker. A technician can confirm with a pressure check.
- What refrigerant gas does my aircon use?
- Most older Singapore aircons (pre-2010) use R22 gas, which is being phased out. Newer units use R32 or R410A. Check the label on your outdoor compressor unit — it will state the refrigerant type. R32 is more environmentally friendly and is now the standard for new installations.
- Is a gas top-up a permanent fix?
- No. If your aircon keeps losing gas, there is a refrigerant leak that needs to be found and repaired. A gas top-up without fixing the leak is a temporary measure. A reputable technician will check for leaks before topping up.
- Can I top up aircon gas myself in Singapore?
- No. Handling refrigerant gas requires a licensed technician in Singapore. Attempting a DIY gas top-up is illegal under the Environmental Protection and Management Act and can damage the compressor.
