In Singapore’s sweltering climate, your air conditioning system must work hard, and it can’t do that without the correct refrigerant levels. At Aircon Service, we offer professional aircon gas top-up services to ensure your system delivers strong, efficient cooling. Whether it’s due to a slow leak or natural depletion, our certified technicians inspect, repair, and refill your air conditioner so it works like new.
Why is Aircon Gas Top-Up Important?
Refrigerant gas is the cooling lifeline of your air conditioner. Without enough of it, the system can’t absorb and release heat efficiently. It means your space won’t cool properly, your system will overwork, and your electricity bills will rise.
Low refrigerant can also cause frost buildup, water leaks, or even permanent compressor damage. That’s why topping up your aircon gas is not just a fix, it’s preventive care that protects your comfort and your wallet.
Studies show that air conditioning units low on refrigerant can lose up to 30% of their cooling capacity and consume up to 25% more energy.
Signs Your Aircon Needs a Gas Top-Up
It’s not always obvious, but a low-gas air conditioner leaves clues. If you experience any of the following, it’s time to call us:
- Your air conditioner is blowing warm air or takes forever to cool the room.
- Ice is forming on the unit’s coil or refrigerant line.
- You hear strange hissing or bubbling sounds indicating a possible leak.
- The unit keeps running but never reaches the set temperature.
- Your electricity bill has spiked with no change in usage.
Don’t wait for complete failure. These signs suggest that your aircon is working harder but cooling less — a problem that only gets worse with time.
Our Aircon Gas Top-Up Process
Our service goes beyond just adding gas. Here’s how we ensure your system keeps working optimally:
System Diagnosis
We check refrigerant pressure, temperature output, and airflow to determine if your air conditioner is low on gas.
Leak Detection
If low gas is confirmed, we inspect the system thoroughly to find and fix any leaks.
Gas Refill
We top up with the correct refrigerant type according to your unit’s specifications.
Types of Refrigerant We Use
Different air conditioning models require specific refrigerants. Our technicians can identify and safely handle the correct type:
- R22 – Older units; still in use but being phased out due to environmental regulations.
- R410A – A widely used and energy-efficient refrigerant in modern units.
- R32 – A newer, eco-friendly option with lower global warming potential (GWP).
We follow manufacturer guidelines strictly to ensure optimal performance and safety.

FAQs
If your air conditioner is in good condition with no leaks, you generally shouldn’t need a gas top-up for several years. Frequent top-ups often mean there’s a leak in the system, which requires repair before adding more refrigerant. On average, well-maintained units may only need a top-up every 2–3 years, but usage patterns and environmental factors can affect this.
Running an air conditioner with low gas is not recommended. It reduces cooling efficiency, forces the compressor to overwork, and can lead to expensive damage. In severe cases, it can cause the compressor to fail, requiring a costly replacement.
You can find the refrigerant type on the label or nameplate on the outdoor unit. Common types include R22, R410A, and R32. If you are unsure, our technicians can quickly identify it during inspection.
The cost depends on your aircon type, refrigerant required, and whether any leaks need repair. Prices generally range from $60 to $150 for residential units. We provide transparent, upfront quotes before starting any work so you know exactly what to expect.
