Refrigerant Leak Detectors | R32, A2L & HVAC Leak Tools

Refrigerant Leak Detectors Australia – R32, A2L & HVAC Leak Detection Tools

A refrigerant leak costs your customer money, damages the environment, and — with A2L refrigerants like R32 — creates a genuine safety risk. A quality electronic leak detector finds leaks fast, confirms repairs, and keeps you compliant. This collection covers heated-diode, infrared, and ultrasonic leak detectors suited to residential splits, commercial refrigeration, and automotive A/C work across Australia.

Types of Refrigerant Leak Detection System Options

Key Features to Compare in an HVAC Leak Detector

• Sensitivity (g/year) — lower is better; 5 g/year is the standard for HVAC compliance work
• Refrigerant compatibility — confirm it detects R32, R410A, R134a, R404A, and HFOs as needed
• A2L rating — essential if you work on R32 systems; the detector must be safe to use around mildly flammable refrigerants
• Probe length and flexibility — a longer, flexible probe reaches tight spots behind coils and in confined spaces
• Sensor life — heated diode sensors typically last ~100 hours; infrared sensors last significantly longer
• Auto background compensation — adjusts for ambient refrigerant contamination to reduce false alarms

Pro Tips for Using an Aircon Gas Leak Detector

• Move the probe slowly — 25–50mm per second — and keep it close to the surface without touching
• Start at the lowest point of the system; refrigerant vapour is heavier than air and settles
• If the alarm triggers, pull back, let the sensor reset in fresh air, then re-approach to pinpoint the exact location
• Always leak-check after repairs before recharging — don’t assume the fix held
• Before using electronic leak detectors on an empty system, perform a standing pressure test using nitrogen pressure regulators to find large leaks fast
