What the Lochinvar Crest Series Is

The Lochinvar Crest Series is a line of commercial-grade condensing boilers built around a stainless steel fire-tube heat exchanger. In Metro Vancouver you will typically find Crest boilers in the mechanical rooms of apartment and condominium buildings, stratas, schools, care facilities, recreation centres, churches and commercial properties — anywhere a hydronic heating plant needs serious output in a compact footprint. They are frequently installed in multiples, staged together by a building controller so the plant can match load as outdoor temperatures swing.

Crest boilers are high-efficiency condensing units in the mid-90s AFUE/thermal-efficiency class, with deep modulation that lets them turn down to a small fraction of full fire. That deep turndown matters in the Lower Mainland, where the heating season is long but usually mild: a boiler that can idle along at low fire during a damp 8°C November week, then ramp up during a January cold snap, runs more efficiently and cycles far less than an older atmospheric boiler ever could. Lochinvar's SMART TOUCH control platform provides on-board diagnostics, cascade sequencing for multi-boiler plants, and outdoor reset.

Because Crest units are larger commercial equipment, everything about them — gas piping, venting, combustion air, condensate handling, relief valves — is sized and permitted differently from a residential boiler. That is exactly why servicing them belongs with a licensed contractor, not a general handyman. CANRO's gasfitters carry Technical Safety BC gas licence LGA0043870 and boiler licence LBP0046450, and we pull the required permits for any regulated work on these systems.

Signs Your Crest Boiler Needs Attention

Commercial boiler plants rarely fail without warning. In the buildings we service around Greater Vancouver, these are the symptoms that most often precede a Crest breakdown:

• Lockouts or fault messages on the SMART TOUCH display, especially repeated ignition failures or flame-loss events
• Short cycling — the boiler firing and shutting down every few minutes instead of modulating smoothly
• Tenant or resident complaints of lukewarm heat or radiators that never quite get hot on cold mornings
• Rising gas bills without a matching change in weather or occupancy
• Water on the mechanical room floor — condensate line blockages, relief valve discharge, or pump seal leaks
• Unusual combustion noise: rumbling, whistling or banging at ignition
• One boiler in a cascade carrying the whole load because its partners are locked out
• Corrosion, scale or white mineral staining around fittings and the heat exchanger area

Any of these is a reason to book a diagnostic visit before a cold snap turns a nuisance into a no-heat emergency for an entire building.

Crest Boiler Repair & Diagnostics

Crest boilers are well instrumented, and a proper diagnosis starts with the control system: we pull the fault history from the SMART TOUCH display, check sensor readings against actual conditions, and run the unit through an ignition sequence while watching flame signal and combustion behaviour. From there we test the usual suspects in a methodical order — gas supply pressure, ignition components, condensate drainage, water-side flow, and the safety chain.

Common Crest fault behaviour we see in Metro Vancouver buildings includes ignition lockouts from worn ignitors or weak flame-sensing signals, blocked condensate traps shutting the unit down (very common here, where boilers condense heavily through our long damp season), pressure and temperature sensor drift, combustion air and vent restrictions, and low water flow from failing circulator pumps or fouled strainers. Rather than guessing at error-code meanings, our technicians verify each fault against the boiler's documentation and live readings before replacing anything.

We do not quote flat repair prices sight unseen, because on commercial equipment that guesswork always ends badly for someone. Instead: a diagnostic visit, a clear explanation of what failed and why, and a free written quote for the repair before any work proceeds. Property managers and strata councils get documentation they can take to their boards.

Parts Replacement for Crest Boilers

Most Crest repairs come down to a specific component, and part availability decides whether a building is back in heat the same day or waiting a week. Lochinvar is well represented in Western Canada, and CANRO sources Crest components through Metro Vancouver commercial HVAC distributors — many wear items are stocked locally, while larger assemblies may need to be ordered in. The components we replace most often:

• Ignitors and flame sensors — the most common wear items; weak flame signal is behind many nuisance lockouts
• Gas valves and gas train components — replaced and then combustion-tested and adjusted to spec
• Combustion fans and blower assemblies — bearing wear shows up as noise and inconsistent air-fuel mix
• Control boards and displays — SMART TOUCH modules and related wiring
• Temperature, pressure and flue sensors — drifting sensors cause phantom faults and poor modulation
• Circulator pumps — boiler and system pumps, seals and motors; low flow will fault a condensing boiler quickly
• Pressure relief valves (PRVs) — a dripping or seized relief valve is a safety device that must be replaced, never plugged
• Expansion tanks — waterlogged tanks cause pressure swings and relief valve discharge
• Condensate traps, neutralizers and drain components — critical in BC, where these boilers condense most of the year
• Heat exchanger components and gaskets — for major heat exchanger damage we assess honestly whether repair or replacement makes better financial sense

Every gas-side part replacement is followed by a combustion analysis and safety check — we never swap a gas valve or fan and walk away without verifying the burner is running clean and within specification. For parts work we quote the same way as repairs: diagnostic visit first, then a free written quote covering parts and labour.

Crest Boiler Installation & Replacement

When a Crest boiler — or the older boiler it would replace — reaches end of life, CANRO handles the full replacement project: heat-loss and load review, boiler selection and staging strategy, removal of the old unit, gas piping, venting, condensate design, pumps and controls, commissioning, and the Technical Safety BC permit and inspection process.

Replacement projects in Lower Mainland mechanical rooms come with local realities we plan for up front: rooftop or sidewall venting routes in older buildings that were never designed for condensing flue gas, condensate neutralization and drainage to code, seismic restraint, and combustion air in tight rooms. Because Crest boilers modulate deeply, we also look hard at whether the existing plant is oversized — it often is — and whether a smaller or differently staged plant would serve the building better.

As a reference point, residential-scale boiler installation in our market typically runs $6,500–$14,000+ and replacement $7,500–$15,000+. Commercial Crest projects are scoped individually — mechanical room condition, venting, controls and building size drive the number — so we provide a free written quote after a site visit rather than a generic figure. CANRO is an independent licensed contractor, not a manufacturer's sales arm, so our recommendation is based on what fits your building, not a quota.

Annual Maintenance & Tune-Ups

Condensing commercial boilers are not install-and-forget equipment. Lochinvar's warranty terms and Technical Safety BC's expectations both assume regular professional maintenance, and in practice an annual service is the single cheapest thing a building can do to avoid mid-winter downtime. A CANRO maintenance visit on a Crest boiler includes:

• Combustion analysis at high and low fire, with burner adjustment to specification
• Inspection and cleaning of the burner and heat exchanger surfaces as needed
• Ignitor and flame sensor inspection or replacement
• Condensate trap and neutralizer cleaning — the most neglected item in BC mechanical rooms
• Venting and combustion-air inspection
• Water-side checks: system pressure, expansion tank charge, pump operation, glycol or water quality where applicable
• Safety chain verification: relief valve, high limits, low-water cutoff where fitted
• Control review: fault history, cascade sequencing, outdoor reset curve, and firmware-level settings
• A written condition report for your records, board or property manager

For multi-boiler plants we schedule maintenance before the heating season so any parts lead time lands in September, not December. Buildings on a maintenance relationship with us also get priority when cold-snap demand stacks up.

Same-Day & After-Hours Service

A locked-out heating plant in a 60-unit building is not a wait-until-Monday problem. CANRO offers same-day and after-hours service across Greater Vancouver — Burnaby, Vancouver, New Westminster, Coquitlam, Richmond, Surrey, North Vancouver, West Vancouver, the Tri-Cities and surrounding communities. Being based in Burnaby puts us within a short drive of most Metro Vancouver mechanical rooms, which matters when a cold snap has every heating contractor's phone ringing.

Call (604) 359-1081 and you will speak with someone who can dispatch a licensed gasfitter, not a call centre reading a script.

Cost Guidance, Rebates & Financing

For repairs, parts replacement and maintenance on Crest boilers we do not publish flat dollar figures — commercial repair scope varies too much for that to be honest. Our process is a diagnostic visit followed by a free written quote, approved before work begins. For installation and replacement, residential-scale work runs $6,500–$14,000+ (installation) and $7,500–$15,000+ (replacement); commercial Crest plants are quoted per project after a site visit.

On the incentive side: the Canada Greener Homes Grant closed to new applicants in 2024, but the Greener Homes Loan program continues to offer interest-free financing for eligible home energy upgrades, and CleanBC and FortisBC run rebate programs for qualifying high-efficiency equipment — including offerings aimed at commercial and multi-unit residential buildings. Eligibility rules and amounts change, so we confirm what your specific building and equipment qualify for at quote time rather than promising numbers that may be out of date. Financing options are available for larger projects; ask when you call.
