Most manufacturers recommend annual servicing. This keeps your warranty valid, maintains efficiency, and ensures flues, burners, and safety controls are functioning correctly.

GAS SAFETY & MAINTENANCE
Smell gas, hear a persistent hiss in the walls, or notice orange-tinged flames and soot around a heater? These symptoms signal a potentially dangerous leak or incomplete combustion. First, switch off the gas at the meter or LPG cylinder. This stops further gas from entering the pipework. Open windows and exterior doors to disperse any build-up, keep naked flames and electrical switches well away from the area, and evacuate anyone who feels dizzy or nauseous. Then contact Build NZ. Our certified gasfitters arrive with calibrated electronic sniffers, ultrasonic leak detectors, manometers, and flue-gas analysers to pinpoint faults quickly. Each van is stocked with regulators, flexi-hoses, thermocouples, valves, and ignition controls, so we can repair most leaks or appliance failures on the first visit. We restore safety, issue a Gas Safety Certificate, and advise on any long-term upgrades to prevent a repeat incident.
For reliable, fully certified gasfitting backed by honest advice, transparent pricing, and more than three decades of Auckland experience, choose Build NZ. We handle everything from simple hob replacements and continuous-flow water heater conversions to large-scale commercial plant rooms, café fit-outs, and multi-storey gas risers. Our team manages design, consent, installation, servicing, and annual compliance testing, providing a single point of contact and a written workmanship guarantee.
FREQUENTLY ASKED QUESTIONS
CAN I SWITCH FROM LPG BOTTLES TO NATURAL GAS?
Yes. If your street has reticulated supply, we can size a new regulator and run a connection from the network to your meter position, then certify any appliance conversions required.
DOES A GAS HOT‑WATER CONTINUOUS‑FLOW UNIT NEED ELECTRICITY?
It uses a small amount of power for the ignition and control board. During a power cut the unit will not fire, but we can discuss battery‑backup or vent‑free alternatives if uninterrupted hot water is essential.
WHAT ARE THE SIGNS OF A GAS LEAK INSIDE THE HOUSE?
Typical indicators include a sulphur or “rotten egg” smell, white mist near joints, hissing sounds, or unexplained higher gas bills. Evacuate the area, isolate the supply, and ring us for an urgent inspection.
DO I NEED A BUILDING CONSENT FOR A NEW GAS FIREPLACE?
In most Auckland districts, indoor flued heaters and any new external pipework penetration require building consent. Build NZ handles the paperwork, council liaison, and final Code of Compliance sign‑off for you.
