Aircon Gas Top Up Singapore

Aircon Gas Top Up Service in Singapore

If your aircon is blowing warm air or not cooling your room properly, the most common cause is low refrigerant gas. As part of our aircon servicing in Singapore, our licensed technicians check your system’s gas pressure levels and top up with the correct refrigerant type — whether your unit uses R22, R410A, or R32 gas.

Unlike some companies that simply add gas without checking for leaks, we always measure suction and discharge pressure first to diagnose the root cause. If your gas is depleting quickly, we provide leak detection services to find and fix the leak before topping up — saving you money on repeated top-ups.

Gas Types and Pricing

The price varies based on the amount of gas needed and your system’s capacity. Our technician will measure the exact amount required and confirm the price before proceeding.

Signs Your Aircon Needs a Gas Top-Up

• Warm or lukewarm air coming from the indoor unit
• Ice formation on the copper pipes or evaporator coil
• Hissing or bubbling sounds near the indoor unit
• Compressor running constantly without reaching set temperature
• Higher electricity bills due to the system working harder

Why Gas Leaks Happen

A properly installed aircon should not lose gas over its lifetime. If your system needs frequent top-ups, there is likely a leak in the refrigerant piping, flare joints, or the evaporator/condenser coil. Common causes include:

• Vibration damage at pipe joints over time
• Corrosion of copper piping, especially in older systems
• Poor initial installation with improperly flared joints
• Physical damage to exposed piping

We offer leak detection to pinpoint the exact location before recommending repair or top-up. Learn more about aircon gas leak signs and dangers.
