Aircon gas top-up in Singapore
A sealed system does not consume refrigerant. If yours is low, it has leaked, and the gas has gone somewhere. That is why we check for the leak before we put anything in.
Topping up a leaking system will cool your room for a few weeks and then you are back where you started, having paid for gas that is now in the air outside. Plenty of companies will do exactly that. We would rather find the leak and quote the repair.
What happens on the visit
Confirm it is actually a gas problem
Weak cooling is more often a fouled coil than low gas. We check the obvious causes first so you are not paying for refrigerant you did not need.
Pressure check and leak trace
Gauges onto the condenser to read the actual pressures, then a trace of the joints and line set to find where it is going.
You get the finding before we do anything
If it is a repairable joint we quote the repair. If it is a slow leak you would rather live with for now, we tell you what a top-up will realistically buy you and let you decide.
Charge to spec and verify
Charged to the manufacturer's spec for the unit, not by feel, then run and measured at the vent so you can see the result.
What’s included
- Pressure check on the system
- Leak trace on joints and line set
- Refrigerant charged to the unit's specification
- Cooling verified at the vent before we leave
What’s not
- Repair of the leak itself, which is quoted separately once we have found it
Anything outside the job gets quoted before we do it, never added at the end.
Low gas usually looks like
- Air from the vent is cool but never cold
- Ice forming on the pipework or the indoor coil
- A hissing or bubbling sound from the unit
- The compressor running constantly without reaching temperature
- Cooling that got gradually worse over months rather than suddenly
Common questions
- How much does a gas top-up cost?
- It depends on the refrigerant type and how much the system takes, so we quote it after the pressure check rather than guessing up front. The diagnostic call-out is $50, and free if you go ahead with the work.
- How often should aircon need topping up?
- Ideally never. A properly sealed system holds its charge for the life of the unit. Needing gas every year means there is a leak worth finding.
- Can you top up R22 systems?
- Yes, though R22 is phased out and increasingly expensive. On an older unit that needs gas repeatedly, we will be straight with you about whether it is worth spending on.
Might not be what you need
Plenty of people land on the wrong page. If either of these sounds closer, follow it — we would rather you booked the right job than the expensive one.
