Aircon Gas Top Up Singapore — R22 & R410A Pricing
Professional aircon gas top-up service for R22 and R410A refrigerants.
Signs You Need Gas Top Up
What's Included
How It Works
Pressure Check
Our technician connects a pressure gauge to measure your current refrigerant level and identify whether a top-up is needed.
Leak Detection
Before topping up, we check for leaks in the piping and connections. Topping up without fixing a leak wastes money.
Gas Top Up & Test
We charge the correct refrigerant (R22 or R410A) to the optimal pressure level and test the unit's cooling output.
Our Work


Why Choose Cool Earth
Per-PSI Pricing Available
Only pay for the gas you need. Per-PSI pricing means you're not overcharged for a minor top-up.
Leak Check First
We always check for leaks before topping up. No point adding gas if it's going to leak out again.
Both R22 & R410A
We carry both R22 and R410A refrigerants. Our technician identifies which gas type your unit uses.
Why Your Aircon Loses Refrigerant Gas
Your aircon relies on refrigerant gas (R22 or R410A) to absorb heat from your room and transfer it outside. When gas levels drop, your aircon struggles to cool effectively — or stops cooling altogether.
Common Causes of Low Refrigerant
- Slow leak in copper piping joints or flare connections
- Vibration damage causing micro-cracks in piping over time
- Corrosion of the evaporator or condenser coil
- Installation defect — improper brazing or loose fittings
- Natural degradation in older systems (10+ years)
Signs Your Aircon Needs a Gas Top-Up
- Aircon not cold — the most common symptom of low refrigerant (see our full guide on why your aircon isn’t cold to check if gas is the issue)
- Ice forming on the evaporator coil or copper piping
- Longer cooling time — the room takes much longer to cool down
- Hissing or bubbling sounds from the indoor or outdoor unit
- Higher electricity bills — the compressor runs longer to compensate
Our Gas Top-Up Pricing
We offer transparent, published pricing for all gas top-up services:
| Gas Type | Per-Unit Price | Per-PSI Price | Common In |
|---|---|---|---|
| R22 | $50 - $80/unit | $2/PSI | Older units (pre-2015) |
| R410A | $60 - $150/unit | $4/PSI | Modern units |
| R32 | Contact for quote | Contact for quote | Latest eco-models |
Per-PSI pricing is available for minor top-ups — you only pay for the exact amount of gas added. This is more cost-effective when only a small amount is needed.
Our Gas Top-Up Process
Step 1: Diagnostic Check
Our technician connects a pressure gauge to your outdoor unit to measure the current suction pressure. This tells us exactly how much gas is needed.
Step 2: Leak Detection
Before adding any gas, we inspect the piping, connections, and coils for leaks. Topping up without fixing a leak is a waste of your money — the gas will just leak out again.
If a leak is found, we’ll explain the repair options and costs before proceeding.
Step 3: Charge & Test
We add the correct refrigerant type to the optimal pressure level specified by your unit’s manufacturer. After charging, we test the unit’s cooling output with a temperature reading to confirm it’s blowing cold air.
R22 vs R410A: Which Gas Does My Aircon Use?
Your aircon uses one specific refrigerant type — you can’t mix them. Here’s how to identify which one you have:
- Check the outdoor unit label — it lists the refrigerant type (R22 or R410A)
- Age of unit — systems installed before 2015 typically use R22; newer ones use R410A or R32
- Our technician will confirm during the diagnostic check
R22 is being phased out globally due to its ozone-depleting properties. If your unit uses R22 and needs frequent top-ups, it may be worth considering a replacement with a modern R410A or R32 system.
