Confused about heated diode vs infrared leak detector technology? This guide explains how each sensor works, compares sensitivity, false alarm resistance, and sensor lifespan side by side, and tells you which technology suits residential splits, commercial HVAC, and refrigeration work in Australia.

Choosing the right leak detector for Australian HVAC work is not just about price. This guide explains how to compare sensor types, refrigerant compatibility, field performance, and long-term ownership costs so tradies and service teams can buy with confidence and avoid costly call-backs.

A leak detector is only as good as its maintenance. In Australian HVAC work, a poorly stored, dirty, or ageing detector can lead to missed leaks, false alarms, wasted labour, and repeat visits. This guide explains leak detector calibration, sensor life, servicing, storage, and replacement in simple practical terms for techs working with R32, R410A, and R22 systems across Aussie conditions.
