Refrigerant top-up prices

Pricing is per fan-coil unit. Older R22 systems are more expensive because supply is limited and being phased out.

R32 (most modern units)From S$80Single fan-coil top-up. Most aircons sold in Singapore after 2018 use R32.
R410AFrom S$100Common in units installed 2010–2018. Slightly higher gas cost than R32.
R22 (legacy)From S$120Phased out. Refill is expensive; we usually recommend planning a replacement.
Full vacuum + re-gasS$180 – $280When the system has been opened or fully depleted. Includes pressure test and vacuum.
Leak check onlyS$60Soap test and pressure check on copper joints and fan-coil. Waived if you proceed with a top-up.
Multi-system top-upS$60 / unit (3+)Top up two or more fan-coils on the same visit for a reduced per-unit rate.

When a top-up is the right fix — and when it isn't

A top-up only treats the symptom. If pressure drops again within months, you're paying for refrigerant to leak straight back out.

Top-up makes senseSmall loss over yearsSlight performance drop over 3+ years on an otherwise well-serviced unit. One refill should hold.
Find the leak firstRefills within monthsIf you've topped up more than once in 12 months, get a leak check — usually the copper joint at the wall.
Chemical wash, not gasBlocked airflowWeak cooling with frost on the coil usually means a dirty fan-coil. Wash first ($90), then re-assess.

FAQ

How often does aircon need a gas top-up?

A properly installed unit should not lose refrigerant. If you need a top-up more than once every two or three years, there is likely a leak that needs to be found and sealed before refilling.

How long does the visit take?

A standard R32 top-up for a single fan-coil takes about 45–60 minutes including a pressure check. Full vacuum and re-gas takes around 90 minutes.

Will a top-up alone fix the cooling?

Often not. Weak cooling can also come from a dirty fan-coil, blocked filter, leaking pipe insulation or a worn compressor. We diagnose first, then decide whether top-up or chemical wash is the right next step.

R32 vs R410A — does it matter?

You can't mix them. The unit is designed for one specific refrigerant; check the outdoor unit nameplate or the model number.

Do you provide a warranty on the gas?

Yes — workmanship and refrigerant are warranted for 30 days against pressure loss caused by the joints we sealed.
