If you’ve noticed that your aircon isn’t cooling as well as before, you might be wondering if it needs a gas top-up. Many Singapore homeowners aren’t sure when this service is necessary, or how to tell if their unit is low on gas (refrigerant).
In this guide, we’ll explain what an aircon gas top-up is, the common signs that your system might need more gas, and why it’s important to schedule a gas top-up early before bigger problems happen. Keeping your aircon gas levels in check ensures your unit runs efficiently and keeps your home cool and comfortable all year round.
What Is an Aircon Gas Top-Up?
First of all, let’s be clear — an aircon gas top-up isn’t something you need to do regularly like a filter cleaning.
It’s a service where a technician refills the refrigerant (cooling gas) inside your aircon system. This gas is essential because it helps cool the air before it’s blown back into your room.
However, in a properly installed and sealed system, refrigerant should never run out on its own. If it does, there’s usually a leak somewhere in the system.
When Does Your Aircon Need a Gas Top-Up?
Now, let’s go through the common signs to watch for:
Weak or Warm Airflow
Firstly, if your aircon is blowing air but it no longer feels cool — even when set to the lowest temperature — this might be a sign the refrigerant level is too low.
Ice Forming on the Aircon Pipes
Next, take a look at your aircon’s exposed copper pipes.
If you notice ice or frost forming on them, this is a clear sign of low gas pressure, which affects cooling performance.
Unusual Hissing or Bubbling Noises
In addition, strange sounds like hissing or bubbling coming from your indoor or outdoor aircon unit could mean there’s a gas leak.
This is a sign you need to call a technician immediately.
Higher Electricity Bills
Another thing to watch for is a sudden increase in your electricity bill.
When your aircon struggles to cool, it works harder and consumes more power.
As a result, your bills go up even though the cooling feels weaker.
Should You Top-Up Gas Without Fixing the Leak?
Many people think they can just add more gas to fix the problem. However, this isn’t a good idea.
If there’s a leak, it should be properly repaired first.
Otherwise, the new gas will escape again, and you’ll keep wasting money on frequent top-ups.
