At AR Contractor Aircon Service, we provide professional and reliable aircon general servicing and gas top-up in Singapore to ensure your cooling system performs at its best throughout the year.
Many people assume their air conditioner simply “runs out of gas,” but in reality, refrigerant does not evaporate or deplete naturally. If gas levels are low, it’s usually a sign of a leak or internal fault. Simply topping it up without solving the root cause can waste both refrigerant and money. That’s why we inspect, detect, and repair leaks first—before performing a gas top-up—to provide you with a long-term solution rather than a temporary fix.

Your air conditioner runs on a sealed refrigerant system, which requires the right gas pressure to function effectively. Newer systems commonly use R32 or R410A refrigerants, while older units may still rely on R22.
When refrigerant levels drop, your air conditioner struggles to cool, consumes more electricity, and may even damage the compressor or coil. That’s why regular aircon general service helps prevent costly breakdowns, ensuring smooth, efficient, and long-lasting performance.
Our General Service Process
1. System Inspection & Pressure Testing
We begin with a pressure check using professional gauges. If your system shows normal pressure, issues may lie in dirty coils, airflow blockages, or compressor faults, and we’ll advise you accordingly.
2. Leak Detection & Repair
If low pressure is detected, we conduct detailed leak checks using electronic detectors and soap tests. Most leaks occur around pipe joints, valve stems, or evaporator coils. When located, our technicians repair them immediately before topping up gas.
3. Vacuum & Gas Refill
After repairing leaks, we vacuum the system to remove moisture and air residues. Then, the correct refrigerant is added in precise amounts, followed by post-service pressure tests to ensure your unit is sealed and optimized for steady cooling.
