Boiler Service & Repair
Expert boiler installation, repair, and maintenance from licensed gas fitters. We service all boiler makes and models across North Vancouver and the Greater Vancouver area.
Complete Boiler Services for Every Home
Your boiler is the heart of your home's heating system, especially in North Vancouver where many older homes in Lower Lonsdale, Central Lonsdale, and the Grand Boulevard area rely on hydronic (water-based) heating systems with radiators or in-floor radiant heat.
At Lord Mechanical, our licensed gas fitters have extensive experience with every type of residential and commercial boiler. Whether your vintage character home in Moodyville has a cast-iron boiler that's seen better days, or your newer Lynn Creek home needs a modern combi boiler installed, we deliver reliable solutions tailored to your property.
We work with all major boiler brands including Navien, Viessmann, Rinnai, IBC, NTI, and Weil-McLain. From routine annual maintenance that keeps your system running at peak efficiency to emergency repairs when your heat goes out on a freezing January night, Lord Mechanical is the North Shore's trusted boiler service provider.

Understanding Your Boiler Options
Choosing the right boiler type is critical for efficiency, comfort, and cost. Here's what you need to know about each type.
Combi Boilers
Combination boilers provide both central heating and hot water on demand — no storage tank required. They're compact, energy-efficient, and ideal for smaller homes or condos where space is at a premium. Popular brands include Navien and Rinnai.
System Boilers
System boilers work with a hot water storage cylinder, making them perfect for larger homes with multiple bathrooms. They deliver strong water pressure to several taps simultaneously and are compatible with solar thermal systems for added efficiency.
Conventional Boilers
Also called regular or heat-only boilers, these use both a cold water storage tank and hot water cylinder. Common in older North Vancouver homes, they're ideal for properties with existing traditional heating systems and high hot water demands.
Signs Your Boiler Needs Attention
Don't wait for a complete breakdown in the dead of winter. Watch for these warning signs that indicate your boiler needs professional service:
- Strange noises — Banging, kettling, whistling, or gurgling sounds indicate limescale buildup, air in the system, or pump failure.
- Uneven heating — Cold radiators or rooms that won't warm up can signal circulation problems, zone valve issues, or a failing pump.
- Frequent pressure drops — If you're constantly re-pressurizing your boiler, there may be a leak in the system or a faulty expansion vessel.
- Yellow or orange flame — A healthy boiler flame should be blue. A yellow or orange flame indicates incomplete combustion and possible carbon monoxide risk.
- Rising energy bills — A sudden increase in gas bills without increased usage suggests your boiler's efficiency is declining.
Boiler Maintenance Schedule
A well-maintained boiler lasts longer, runs more efficiently, and keeps your family safe. Here's what our annual service includes:
Combustion Analysis
We test flue gases to ensure proper combustion, verify carbon monoxide levels are safe, and check gas pressure at the manifold and burner.
Heat Exchanger Inspection
Visual and functional inspection of the heat exchanger for cracks, corrosion, or scaling that can reduce efficiency and pose safety risks.
Safety Controls Check
Testing all safety devices including pressure relief valves, temperature controls, flame sensors, and low-water cutoffs.
System Flush & Clean
Cleaning burners, flushing the system to remove sediment, checking expansion tank pre-charge, and topping up inhibitor to prevent corrosion.
Boiler Service FAQ
A well-maintained boiler typically lasts 15–20 years. However, efficiency declines after 10–12 years, so upgrading to a modern condensing boiler can significantly reduce your energy bills even if your current unit is still functional. We can assess your boiler's condition and help you decide whether repair or replacement is the better investment.
Common warning signs include strange noises (banging, whistling, gurgling), uneven heating or radiators not getting hot, frequent pressure drops, the pilot light going out repeatedly, visible leaks or corrosion, and a yellow or orange flame instead of blue. If you notice any of these signs, call us promptly to prevent a complete breakdown.
Minor boiler repairs typically range from $200–$600, while major component replacements (heat exchanger, control board) can cost $800–$2,000+. We provide upfront written quotes before starting any work so there are no surprises. Our technicians carry common replacement parts on their trucks to complete most repairs in a single visit.
If your boiler is over 15 years old, requires frequent repairs, or your energy bills are steadily increasing, replacement is usually more cost-effective. A new high-efficiency condensing boiler can reduce fuel costs by 20–30% and may qualify for BC energy rebates. We'll give you an honest recommendation based on your boiler's age, condition, and repair history.
For most North Vancouver homes, combi boilers are excellent for smaller properties as they provide hot water on demand without a storage tank. System boilers suit larger homes with multiple bathrooms. We assess your home's hot water demands, number of bathrooms, existing infrastructure, and available space to recommend the ideal boiler type and size.
