StringsSG Aircon Gas Top-Up Singapore
By StringsSG – Trusted Local Home Service Partner
BCA-Certified Aircon Technicians
Air conditioning systems require refrigerant gases like R22, R410A, or R32 to function effectively. Low gas levels cause poor cooling, compressor strain, and higher electricity bills. At StringsSG, our experienced and BCA-certified technicians use calibrated gauges to diagnose refrigerant issues accurately and perform top-ups in a safe, eco-friendly manner.
All gas refill services follow NEA-compliant safety protocols, ensuring both optimal cooling performance and environmental responsibility. We source our refrigerants only from licensed suppliers to guarantee authenticity and quality.
If you're on a maintenance package, refrigerant level checks are included in every visit. Refills are charged separately based on gas type and quantity, with transparent pricing displayed before service begins.

Gas Top-Up Pricing
Prices depend on gas type, volume required, and your aircon system. Here's a typical range in Singapore:
| Gas Type | Price (SGD) |
|---|---|
| R410A | SGD 60 – SGD 150 |
| R32 | SGD 100 – SGD 200 |
| R22 | SGD 40 – SGD 100 |
Signs Your Aircon Needs Gas Top-Up
- 🌬️Weak cooling – Air isn’t as cold as before.
- ⏱️Longer cycles – Takes longer to cool the room.
- 🔄Compressor never stops – Constant or irregular operation.
- ❄️Ice buildup – Frost on coils or copper pipes.
- 💨Hissing sounds – Could indicate a refrigerant leak.
- ⚡High electricity bills – Caused by poor cooling efficiency.
If you notice any of these signs, don’t delay. StringsSG’s certified technicians can inspect, diagnose, and safely refill your aircon gas. Learn more about gas leakage.

Types of A/C Refrigerant Gas

Performing an aircon chemical wash yourself can be complex and dangerous as it involves handling chemicals and electrical components. It's best to hire professionals with the proper tools and safety knowledge. If you still wish to proceed DIY, please be cautious and informed.
1. R-22 (Chlorodifluoromethane)
Once widely used, R-22 is being phased out globally due to ozone depletion issues under the Montreal Protocol.
2. R-410A (Puron)
R-410A replaced R-22 in many systems. It's more environmentally friendly as it doesn’t deplete the ozone layer.
3. R-134a (1,1,1,2-Tetrafluoroethane)
Used in automotive and commercial systems, R-134a has no ozone depletion effect but contributes to global warming.
4. R-407C
Designed to replace R-22 in existing systems, R-407C is ozone-safe but still contributes to global warming.
5. R-32 (Difluoromethane)
Common in newer residential units, R-32 offers lower global warming potential compared to many HFCs.
6. R-290 (Propane) and R-600a (Isobutane)
Eco-friendly hydrocarbon refrigerants with very low global warming impact, used in small-capacity systems.
Refrigerant use and availability are changing due to evolving regulations and environmental concerns. Stay updated with newer, safer alternatives.

Should You Top Up Aircon Refrigerant Gas Yourself?
Topping up aircon refrigerant gas yourself is not recommended. It involves hazardous substances and requires certifications.
Mishandling refrigerants like R-410A or R-22 can cause health hazards and damage your unit. Only licensed HVAC technicians should handle them.
If your system isn't cooling well, seek help from certified professionals to ensure safety and efficiency.
