📞 (604) 359-1081Book boiler serviceYou can safely note when the noise happens (start-up, full heat, certain zones) to help us diagnose it, but don’t open the boiler or attempt a power-flush yourself. Persistent kettling shortens boiler life — book a service.
Stop using the system and call CANRO if you smell gas, see soot or signs of incomplete combustion, have water leaking near electrical parts, or the boiler keeps locking out. Anything involving gas, pressure, the pump, valves, venting or internal controls needs a licensed technician. Call (604) 359-1081 or book online — same-day diagnostics when our schedule allows.
Safety first — please don’t DIY this. Do not open the boiler, touch gas or electrical parts, adjust the pressure or gas valve, work on the pump, venting or safety controls, or relight anything you’re unsure about. If you smell gas or suspect carbon monoxide, leave the home immediately, call your gas utility’s emergency line, then call us. The only safe homeowner steps are checking the thermostat is calling for heat, confirming the power switch and breaker are on, and checking the pressure gauge reading to report it to us. Anything more should wait for a licensed technician — call (604) 359-1081.
Our technicians are familiar with every major residential boiler brand, including the three we’re asked about most:
We service these brands — we make no “authorized” or “official service centre” claims. What we offer is genuine experience, licensed gas and boiler technicians, and honest pricing.
A residential boiler combines gas (or oil), high-temperature water under pressure, electrical controls and sealed combustion. Work on any of those by an untrained hand is genuinely dangerous — gas leaks, carbon monoxide, scalding and electrical shock are all real risks. In BC, gas and boiler work must be done by a TSBC-licensed technician, and doing it yourself can void your warranty and your insurance. A CANRO technician diagnoses your boiler properly, repairs it to code, and confirms it is safe before leaving. If a part is unsafe or worn, we tell you honestly.

Often kettling from scale or sludge restricting flow, trapped air, or a weak pump. A technician can flush, bleed or repair as needed — left alone it stresses the boiler.
It’s usually a performance and longevity issue rather than an immediate danger, but it signals a fault worth fixing. If banging comes with a gas smell or shutdowns, treat it as urgent.
Usually yes — descaling/flushing, bleeding air, or replacing a pump resolves most noises. We diagnose the cause rather than guess.
