Pressure testing with nitrogen is the “leak gate” that saves time and prevents call-backs. This guide shows a practical, step-by-step field method with safe setup, stabilisation, hold testing, and clear pass/fail criteria you can document.

Recovery is easiest to defend when it’s repeatable. This guide walks through a step-by-step refrigerant recovery workflow for Aussie HVAC/R tradies—how to choose and weigh cylinders, manage heat and hose layout, avoid mixing refrigerants, and write clean ARC-style notes without turning every job into paperwork.

Evacuation isn’t “run the pump and hope.” This step-by-step workflow shows how to reduce restriction, measure system-side with a micron gauge, prove stability with an isolation (hold/decay) check, and document results so your commissioning is defensible.

A micron gauge takes the guesswork out of evacuation. This guide shows you how to place the gauge system-side, pull down to a sensible benchmark, run an isolation (decay) test, and write clear evacuation notes that help prevent costly call-backs.

Australia’s dust, humidity, and coastal salt make air conditioners clog faster than most people expect. This practical guide explains what “aircon cleaning” really includes, how to clean indoor and outdoor units safely without damaging fins or soaking the room, how often to clean by local conditions, and what to ask for in a proper professional deep clean.

Not sure what to buy first (or what actually reduces call-backs)? This guide maps out the best HVAC tool kits for Aussie standards, from apprentice starter gear through to pro-level diagnostics. You’ll see what matters most for repeatable temperature checks, when to add data logging, where thermal imaging fits, and why install kits must include proper evacuation verification.

Intermittent HVAC faults love hiding between service visits. A data logger captures the full story over time—temperature, humidity and cycling—so you can prove when the problem happens, choose the right follow-up test, and show clear “before and after” results without over-claiming.

Thermal imaging can save hours on HVAC fault-finding—if you don’t get tricked by shiny metal, sun load, wind, or wet surfaces. This guide shows what a thermal camera really measures, the most useful HVAC use cases, the common false-reading traps, and a repeatable “scan, confirm, decide” workflow for split systems and commercial gear—plus how to report results without over-claiming.

Static pressure is the quiet number behind noisy ducts, weak rooms, and coil icing. This guide shows how to use a manometer to find restrictions fast—where to test, how to read the patterns, and how to prove the fix with airflow checks.
