Quick answer: Here’s a clear, homeowner-friendly answer for Greater Vancouver — plus when it pays to get a licensed technician’s assessment. CANRO offers free written quotes on installations and upfront pricing on repairs; call (604) 359-1081.

Understanding “Combi boiler lime scale warning signs” before you spend money is smart. This guide keeps it practical and local, with honest numbers and no DIY on gas, system pressure, the pump, valves or venting.

Greater Vancouver’s damp, mild climate and its mix of older character homes, heritage houses, condos, townhomes and newer builds all affect how boiler problems show up — and our technicians diagnose them every week across Vancouver, Burnaby, Richmond, Surrey, the North Shore, the Tri-Cities, Delta and Langley. A local team that knows BC homes and BC code makes a real difference.

What to consider

The right answer depends on a few things specific to your home:

  • Low system pressure or a waterlogged expansion tank — one of the more common explanations our technicians confirm or rule out during diagnosis.
  • Trapped air or a circulator-pump issue — one of the more common explanations our technicians confirm or rule out during diagnosis.
  • A zone-valve or thermostat fault — one of the more common explanations our technicians confirm or rule out during diagnosis.
  • Scale or sludge restricting flow — one of the more common explanations our technicians confirm or rule out during diagnosis.
  • An ignition or lockout fault — one of the more common explanations our technicians confirm or rule out during diagnosis.

Your home’s age, size, ductwork and existing system all matter too — as do available FortisBC, CleanBC and federal rebates on efficient upgrades.

Our honest take

We’ll give you the real numbers — repair vs replace, efficiency, rebates and financing — so you can decide with confidence. We never push equipment you don’t need, and we’ll tell you if your current system has good years left.

What to expect when you call CANRO

A licensed CANRO technician diagnoses the true cause by measuring — not guessing — then gives you an upfront written quote before any work begins. We carry common parts, work to code, pull the permits required, and tell you honestly whether a repair or a replacement is the better value. No pressure, no surprises, and same-day diagnostics when our schedule allows.

Frequently asked questions

Is an upgrade worth it?

Often — when equipment is old, inefficient or unreliable, especially with rebates offsetting the cost. We’ll show you the payback for your home.

Do rebates apply?

Efficient heat pumps and hybrid water heaters qualify for the largest BC rebates; we confirm eligibility and handle the paperwork. See our rebates page.

Should I get a professional assessment?

Yes — a proper assessment (and a load calculation for new equipment) prevents costly sizing mistakes. Anything involving gas, system pressure, the pump, valves or venting is licensed work.

Can you finance it?

Yes — we offer flexible financing so you can upgrade now and pay over time, combined with any rebates you qualify for.

Good to know

Frequently asked questions

How often should a boiler be serviced?
Annual servicing is recommended for all residential boilers. CANRO's annual service includes combustion analysis, heat exchanger inspection, expansion tank pressure check, condensate trap cleaning, and a full safety check. Annual maintenance is also required to keep most manufacturer warranties valid.
How much does a new boiler cost in Vancouver?
A typical residential high-efficiency gas boiler in Metro Vancouver costs $7,500–$15,000 installed, depending on size, brand, and whether the system is heating only or a combi unit that also handles hot water. CANRO provides a free written quote with three options at different price points.
How long does a boiler last?
A well-maintained cast-iron boiler can last 25–30 years, a modern high-efficiency condensing boiler typically lasts 15–20 years, and a combi boiler 12–18 years. Annual servicing has the single biggest impact on lifespan.
My boiler is making a banging or kettling noise. Is that dangerous?
Kettling (a banging or whistling sound) is usually caused by limescale build-up on the heat exchanger and is a sign the system is overheating in localised spots. It will not always cause immediate failure but it shortens the life of the boiler and should be addressed within a few weeks.
Do you service Viessmann, IBC, Baxi, Laars, and Weil-McLain boilers?
Yes. CANRO is one of the few HVAC companies in the Lower Mainland with deep experience on European and high-end North American boilers including Viessmann, IBC, Baxi, Laars, Weil-McLain, NTI, Navien and Rinnai. We carry common parts in the truck.
Should I repair or replace my old boiler?
A useful rule: if the boiler is more than 15 years old and the repair cost is more than 50% of replacement, replacement is the better investment. CANRO will give you both a repair quote and a replacement quote and let you decide.
What HVAC services does CANRO offer in Metro Vancouver?
CANRO installs, services and repairs boilers, furnaces, heat pumps, hot water tanks, tankless water heaters, gas fireplaces and air conditioning across Metro Vancouver. We work on residential homes, townhouses and condos throughout the Lower Mainland.
How long has CANRO been in business?
CANRO has been serving the Greater Vancouver area since 1999. Our founder George is recognised by customers as one of the most experienced boiler and hydronic heating technicians in the Lower Mainland.
What areas do you serve?
We cover all of Metro Vancouver: Vancouver, Burnaby, Richmond, Surrey, Coquitlam, North Vancouver, West Vancouver, New Westminster, Delta, Langley, Port Moody, Port Coquitlam, White Rock, Pitt Meadows, and Maple Ridge.
