Whether your Port Coquitlam home is an older Lower Mary Hill bungalow or a newer build up toward Citadel Heights, replacing a combi boiler starts with the same honest assessment.

Quick answer
Replacing an IBC DC Series combi boiler in Port Coquitlam comes down to the heat exchanger's condition, how often the unit has needed repairs, and whether it still meets the home's hot water and heating demand. CANRO assesses the existing system on site in Port Coquitlam before recommending replacement, an upgrade, or simply another repair.

Corrosion or a persistent leak at the primary heat exchanger is the clearest signal that another repair no longer makes sense, since that part is expensive to replace on its own relative to the unit's overall value. Repeated, unrelated failures within a short window — an ignition fault this year, a diverter valve issue the next — are also worth weighing against replacement, particularly if hot water performance has been declining despite repairs.
In older Port Coquitlam neighbourhoods like Lower Mary Hill and Birchland Manor, where a fair number of post-war bungalows still run their original mechanical systems, an aging boiler is often paired with aging piping and venting, which changes what a straightforward replacement actually involves.
Port Coquitlam runs from flatter, older neighbourhoods near the Coquitlam River and the PoCo Trail up into newer hillside subdivisions toward Citadel Heights and Oxford Heights. On an older flat-lot bungalow, a replacement is usually a straightforward like-for-like swap once venting and gas supply are confirmed adequate. On a newer hillside property, access and the specific placement of the mechanical room relative to the exterior wall matter more for how the vent and condensate lines get run.
Because a combi boiler handles both space heating and domestic hot water, a household's actual hot water habits matter more here than they would for a heat-only boiler — added bathrooms, a growing family, or a basement suite are all worth discussing at the assessment rather than assuming the replacement should match the old unit exactly.
A diagnostic or assessment visit runs $90–$150, credited toward any work that follows. Boiler installation typically runs $6,500–$14,000 or more, and a full boiler replacement typically runs $7,500–$15,000 or more, both as a 2026 public-market ballpark, not a quote — the actual figure depends on the unit, venting changes, and any gas line or electrical work uncovered during the assessment. Any replacement requires a gas permit through the City of Port Coquitlam, which CANRO pulls and manages as part of the job.
Work is scheduled around permit timing and equipment availability rather than a promised turnaround. On the day itself, the old unit is disconnected and removed, the new equipment is set, piped, wired, and vented, the gas line is pressure-tested, and the system is commissioned with a combustion and condensate check before the job is handed back to you.
Safety note
If you ever smell gas, hear hissing near the boiler, or a carbon monoxide alarm sounds, leave the house first and call FortisBC's line at 1-800-663-9911 before doing anything else. Do not attempt to relight a gas appliance yourself. Gas boiler replacement in BC must be done under permit by a Technical Safety BC licensed gas fitter; CANRO holds gas licence LGA0043870 and boiler licence LBP0046450.
That depends on your home's current heating and hot water demand and how the existing venting and gas line fit a new unit — CANRO lays out both options honestly at the assessment rather than assuming a like-for-like swap is automatically right.
Sometimes — older Port Coquitlam homes occasionally have venting that predates current combi boiler requirements, which is exactly what the on-site assessment is meant to catch before a quote is finalized.
Yes, a gas permit through the City of Port Coquitlam is required for replacement, and CANRO handles pulling and closing it out as part of the job.
Timing depends on permit processing and equipment availability rather than a fixed promise, though the physical install itself is usually completed in a single day once everything is on site.
That's exactly what the assessment is for — measuring your household's actual hot water demand, including planned additions, rather than assuming the old unit's capacity still fits.
Yes — if a repair is the sound economic choice for your specific unit, that's what we'll recommend instead of pushing a replacement you don't need yet.
