Why Your Aircon Might Need a Gas Top-Up
Air conditioners do not consume refrigerant the way a car burns fuel. In a perfectly sealed system, the same gas circulates indefinitely. So if your unit is low on refrigerant, it almost always means there is a leak somewhere — at a flare joint, along a copper pipe, or within the coil itself. Simply topping up without finding and fixing the leak means the gas will escape again within weeks or months.
That said, there are situations where a straightforward top-up is the right approach: a new installation where the factory charge was insufficient for a longer-than-standard pipe run, or a system that was recently repaired and needs re-charging. Our technicians will assess which scenario applies to your unit before recommending any work.
How do you know the gas might be low? The most obvious sign is warm air blowing from the indoor unit even when set to 16°C. Other clues include ice forming on the copper pipe at the outdoor unit, the compressor running continuously without cycling off, higher-than-usual electricity bills, and a hissing sound near the connections. If you spot any of these, it is worth getting the system checked before the compressor is damaged from running under stress.
We work with all common refrigerant types used in Malaysia — R22 (for older units still in service), R410A, and R32. Each gas requires different handling pressures and equipment. Mixing gas types or using the wrong one will damage the compressor, so it is important to have the correct refrigerant identified and charged by a qualified technician.
