Below is a CANRO technician's perspective on boilers as they apply in Metro Vancouver: what to look for, what to avoid, and what to expect. Carrier is American (founded 1915, invented modern A/C), best known for its Infinity 98 variable-speed modulating gas furnace and Greenspeed cold-climate heat pump. The brand's strengths are broad parts availability across Metro Vancouver, strong dealer training network, well-engineered combustion.
Vancouver's moderately hard tap water (around 60-100 ppm hardness in most of Metro Vancouver) affects tankless water heaters, combi boilers, and hot-water tanks — annual descaling is essential. CANRO has worked with Carrier systems across Metro Vancouver since 1999, from older retrofits in Guildford and Brentwood to new builds in Port Moody and Fleetwood. Carrier is generally a strong fit for mainstream Vancouver homes prioritising parts availability and balanced cost-vs-performance.
Sizing. Boiler sizing depends on heat-loss calculations (Manual J for the home + emitter capacity check). Oversized boilers short-cycle, which is the single biggest cause of premature heat-exchanger failure in Vancouver hydronic installs.
Lifespan. A well-maintained condensing boiler typically lasts 15-20 years in Vancouver. Cast-iron heritage boilers can run 30+ years, but their efficiency (60-75% AFUE) often makes replacement worthwhile after 20 years on energy savings alone.
Warning signs. A failing boiler typically shows kettling (banging or whistling at start-up), expansion-tank pressure loss requiring frequent top-ups, sooty combustion residue, persistent error codes, or radiators that no longer balance.
Over 25+ years of Carrier service calls across Metro Vancouver, the recurring issues we see are: pressure-switch faults on 90%+ models, inducer-motor failure at the 10-12 year mark, condensate-drain freeze in unconditioned spaces.
Parts availability. Carrier parts are stocked at multiple Lower Mainland wholesalers, so emergency repairs rarely wait more than a day.
Annual servicing is recommended for all residential boilers in Metro Vancouver. The service includes combustion analysis, heat-exchanger inspection, expansion-tank pressure check, condensate-trap cleaning, circulator pump check, and a full safety inspection. Annual maintenance is also required to keep most manufacturer warranties valid.
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 long-term investment because newer units run at 95%+ AFUE vs 75-82% for older models — paying back the difference in energy savings over 6-10 years. CANRO gives you both quotes and lets you decide.
A typical residential high-efficiency gas boiler installation in Metro Vancouver costs $7,500-$15,000 depending on size, brand, and whether the system is heating-only or a combi unit also handling domestic hot water. Premium European brands (Viessmann, Baxi) sit at the upper end; North American brands (Navien, IBC, Rinnai) at the lower-middle.
A heating-only boiler heats only the hydronic loop (radiators, in-floor radiant, air-handler coil); a separate hot-water tank handles domestic hot water. A combi (combination) boiler heats both — eliminating the tank but requiring a higher-BTU boiler to handle peak DHW demand. Combi installs work best for 1-3 bathroom homes; heating-only + tank is usually better for 4+ bathroom homes.
Pressure loss indicates either: an expansion tank that has lost its air charge, a leak somewhere in the loop (often a tiny pinhole behind a radiator or under flooring), a weeping pressure-relief valve, or a faulty automatic fill valve. CANRO uses pressure-decay testing and infrared imaging to locate hidden leaks.
Kettling is a banging or whistling sound caused by limescale build-up on the heat exchanger, which creates localised overheating spots. It will not always cause immediate failure but it shortens boiler life significantly and should be addressed within a few weeks by descaling and water-chemistry correction.

“Canro does an amazing job! Super professional and skilled with everything—boilers, furnaces, and AC. Always a pleasure working with them!”
“Five stars for Canro. We needed a replacement of a 30-year-old boiler. A new high-efficiency unit was installed—clean, professional work.”
“I can’t speak highly enough about George, who was recommended for a boiler service call for my parents’ home. George is excellent.”
