Why Your Aircon Is Not Cold — And How Aircon Gas Top Up in Singapore Can Fix It
Is your aircon no longer blowing cold air like it used to? Do you still feel warm even when your temperature is set to 18°C?
One of the most common reasons for weak cooling is low refrigerant levels, also known as low aircon gas. In Singapore’s hot weather, your aircon works hard every day — and over time, gas leaks or natural depletion can happen.
Fortunately, there’s a simple solution: Aircon gas top up in Singapore.
In this article, we’ll explain why refrigerant levels drop, how to detect gas-related problems, and when you should get a gas top-up.
Aircon gas (also called refrigerant) is the cooling agent responsible for absorbing heat and releasing cold air into your room. Without enough gas, your aircon cannot cool effectively, no matter how low you set the temperature.
The two most commonly used refrigerants in Singapore are:

Here are the warning signs that your aircon gas level is low:
❄️ Weak cooling even after cleaning
💧 Water leaking from the aircon unit
⚡ Higher electricity bills than usual
🔊 Hissing noise from the indoor or outdoor unit
❗ Error code related to pressure or compressor
If your aircon is still blowing air but not cold, it’s likely a refrigerant issue.
Technically yes — but you shouldn’t. Running an aircon with low gas forces the compressor to overwork, which can lead to a major breakdown.
Replacing a compressor can cost hundreds of dollars, while a gas top-up is far more affordable. Prevention is always better than repair.

💡 However, if gas leaks repeatedly, a proper leak check and sealing is required — not just a top-up.
A properly maintained aircon shouldn’t require frequent gas refills — unless there’s a leak. Typically:

The best way to know is to schedule professional servicing with pressure testing.
If your aircon feels like a fan, not a cooler — aircon gas top up might be the quick fix you need. It's affordable, fast, and restores cooling instantly, especially when performed by a reliable aircon technician.
Don’t wait until your compressor fails — check your refrigerant level early and keep your aircon in peak condition to beat Singapore’s heat.
