Looking at a car AC regas kit? Learn what a licensed automotive technician uses, why a low-side gauge cannot confirm the charge, and how to read the included R-134a saturation table. The guide also covers Australian refrigerant-handling requirements and common equipment-selection errors.

A single split, multi-split and ducted system call for different planning on site. Compare their layouts, then use the job-based tool checklist to check pipework, evacuation, airflow testing and controls against the actual equipment.

R-32, R-410A and R-454B have different safety classes, climate impacts and equipment requirements. This Australian guide compares them, explains the HFC phase-down, and shows which tool ratings and service connections to check before working on a system.

A coil cleaner is the chemical used on a suitable coil. An AC cleaning kit helps you apply cleaner and contain wash water, and some kits include both. See what each product does, when you may need them together, and what to check before buying.

Brivis ducted gas heaters are built to last, but when a component fails after years of service, the right replacement part gets the system back on quickly without replacing the whole unit. This guide covers every key replacement part in the Brivis gas ducted heater range: gas valves, burner zip tubes, pressure switches, thermocouples, control boards, and transformers. Includes a full component reference table, cross-brand compatibility guidance for Braemar and Bonaire, and selection criteria for every part type.

Replacing a Brivis wall controller doesn't have to mean guesswork. This guide walks through the NC-6, NC-7, Touch Wi-Fi Kit and GDH manual thermostat, showing how to identify what's already on your wall and match it to the right replacement. We'll also cover compatibility checks, wiring clues, and when a swap turns into a bigger upgrade conversation — so you order the right part the first time.

If you have narrowed a Brivis evaporative cooler fault down to the PCB or control module, the next step is confirming which specific module your unit uses. The 526 PCB add-on module, the 516 low voltage network module, and the TEK467 electronic control box are not interchangeable and each suits a different control architecture. This guide explains what each one does, how their fault symptoms differ, how to read the BSB part code to confirm compatibility, and which unit types each module suits.

When a Brivis evaporative cooler stops responding or runs incorrectly, the fault is almost always in the electronic control layer rather than the fan, pump, or pads. This guide covers the key replacement parts for Brivis evaporative coolers: the 526 PCB add-on module, the 516 low voltage network module, the TEK467 electronic control box, and the NC-6 Networker controller. Includes a component fault symptom table, guidance on BSB part codes, and how to identify the correct module for your unit.

When a Brivis gas heater stops working, most homeowners want to know what they can legally do themselves and what requires a professional. The answer is clearer than most expect. This guide covers exactly what is legal for any homeowner to do, including fault diagnosis, component testing, filter maintenance, and parts sourcing, what requires a licensed gas fitter under AS/NZS 5601, and the one situation where you should stop immediately and call for emergency help.

Brivis, Braemar, and Bonaire ducted gas heaters share a common engineering platform, which means a significant number of spare parts are interchangeable across all three brands. This guide covers exactly which components cross over, including the N-E6 control board, White Rodgers 24V gas valve, and pressure switches across all Pa ratings, what differs between brands such as heat exchangers and wiring looms, and the only reliable method for confirming compatibility before you order: matching by BS part code.

A Brivis heater that won't ignite is one of the most common call-outs at the start of winter — and most faults come down to five key components. This diagnostic guide walks through the full ignition sequence, then covers pilot burner and ignition assembly faults, thermocouple failure, thermistor errors, pressure switch lockout, and control board faults. Includes a fault symptom reference table and guidance on what homeowners can legally diagnose vs what requires a licensed gas fitter.

Ordering the wrong Brivis spare part almost always comes down to one thing — not having the correct part number before placing the order. This step-by-step guide shows you exactly how to find the data plate on your Brivis heater, read BS part codes, confirm gas type (NG vs LPG), identify the correct pressure switch Pa rating, match transformer amperage, and tell the difference between N-E6 control board variants. Get it right the first time.
