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.

Expert Tip: A healthy refrigerant level not only improves cooling but also extends your aircon's lifespan. Schedule a check at least once a year for the best performance.

Types of A/C Refrigerant Gas

R22 gas cylinders

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.
