HVAC, boiler and hot water services for high-rise, strata and multi-family buildings

A strata council doesn’t call a contractor the way a homeowner does. There’s a property manager in the loop, a budget line that has to clear an AGM or a special resolution, and two hundred units that all lose hot water at once if the plant goes down mid-repair.

That’s a different job than servicing a furnace in a detached house, and it needs a technician who has actually stood in a boiler room reading pressure gauges at 6 a.m. before residents start their showers, not someone quoting from a brochure.

HeatLand has worked on central plants and common systems across Metro Vancouver and the Fraser Valley since 1999. This page covers what that service actually involves, how the council decision process usually runs, and what a phased replacement looks like when the goal is zero surprise outages.

What multi-family HVAC service actually covers

In a single-family home you’re servicing one furnace and maybe one hot water tank. In a high-rise or a multi-building strata, the mechanical footprint is a boiler room, a network of distribution piping running to every unit or corridor, and a separate domestic hot water system that has nothing to do with space heating. Corridor heating, parkade ventilation, and make-up air units for common areas often run on their own controls, sometimes original to construction, sometimes retrofitted at some point without full documentation. Before any service call goes past a basic inspection, we walk the mechanical room and trace what’s actually connected to what — drawings on file don’t always match what’s been altered over twenty or thirty years. That audit step matters more here than almost anywhere else in residential-adjacent HVAC work, because a shutoff valve mislabeled on a drawing can mean shutting down heat to the wrong wing by mistake. Service on these buildings covers boiler plant maintenance and repair, common hot water system service, corridor and common-area heating, and the controls and pumps that circulate everything. It does not typically extend into individual unit HVAC (in-suite fan coils, baseboard heaters, or unit-level thermostats) unless that scope is explicitly part of the strata’s maintenance responsibility under the bylaws — check your strata’s specific responsibility schedule, since this varies building to building.

Central boiler plants: scale and redundancy change everything

A central boiler plant serving fifty, one hundred, or several hundred units is built around redundancy in a way a single-family system never is. Most plants run two or more boilers in a lead-lag configuration — one carries the base load, a second stages on during peak demand or covers if the first faults out. The point of that arrangement is that a single boiler failure shouldn’t mean no heat for the building; it means reduced capacity while the fault gets diagnosed and repaired. That only works, though, if the sequencing controls are actually configured and tested correctly, and if staff or the property manager know how to read a fault code well enough to call for service before a partial outage becomes a full one. We don’t guess at what a specific fault code means for your make and model — every manufacturer’s control panel documents its own codes, and the right move on an unfamiliar alarm is to check the panel manual or contact the manufacturer, not assume. What we do bring is diagnostic experience: pressure and temperature readings across the loop, checking for short-cycling, verifying combustion air supply hasn’t been compromised by other building work, and confirming the venting is still doing what it was designed to do. Plant age matters too — a system installed when the building went up may be well past the point where parts are easy to source, which is part of why replacement planning starts years before a failure, not after one.

Common hot water systems: separate from space heating, separate risks

Domestic hot water for a multi-family building is usually its own system — a dedicated water heater bank, a storage tank, or an indirect setup drawing off the boiler plant through a heat exchanger — and it fails on its own schedule, independent of space heating. Residents notice hot water problems immediately and loudly, because unlike a heating fault on a mild day, cold showers get reported the same morning. Recirculation loops are common in taller buildings so hot water doesn’t take five minutes to reach a top-floor unit; when that loop’s pump or balancing valves drift out of adjustment, some units run hot and others run lukewarm, which reads to residents like a bigger problem than it usually is. We check flow balance across risers, verify tank or heat exchanger temperatures are within a safe and sensible range, and inspect for the sediment and mineral buildup that shows up in any hot water system over years of operation — Metro Vancouver’s municipal water is soft, so what accumulates in a tank here is generally sludge and sediment settling out over time rather than hard-water scale, and the cleaning approach reflects that. We don’t make claims about what your specific tank warranty or your building’s insurance policy covers if a heat exchanger fails — that’s between your strata and the manufacturer or insurer, and the policy documents or manufacturer will have the actual answer. Our job is diagnosing the mechanical fault and giving you options in writing.

Corridor heating and make-up air

Corridors, stairwells, and parkades in a multi-family building are usually conditioned by systems separate from both the boiler plant and the domestic hot water system — electric or hydronic corridor heaters, and make-up air units that bring in and temper outside air to replace what’s exhausted by suite fans, dryer vents, and parkade ventilation. These systems get less attention than in-suite comfort because no single resident is watching them closely, but they matter for two practical reasons. First, undersized or malfunctioning make-up air can create negative pressure in a building, which shows up as doors that are hard to open, whistling around window frames, or smells traveling between units that shouldn’t be sharing air. Second, corridor heating failures in a coastal winter climate can let unheated common areas run cold and damp long enough to contribute to condensation and mildew on walls and ceilings, which becomes a maintenance issue well beyond HVAC. Service on these systems means checking that dampers are actually opening and closing as designed, that heating elements or hydronic coils are functioning across the full run of corridor, and that controls haven’t drifted out of the sequence they were commissioned to run. In older buildings, some of this equipment predates current building code ventilation standards; we’ll flag where equipment looks original to a 1980s or 1990s build so your strata can weigh repair against eventual code-driven replacement.

How the strata council decision process usually works

Getting mechanical work approved in a strata is procedural in a way it isn’t for a homeowner, and the process shapes how we scope and quote the job. Routine maintenance and small repairs usually fall within a council’s or property manager’s existing spending authority and can move quickly. Anything larger — a boiler replacement, a hot water system overhaul, major corridor heating repair — typically needs council approval first, then often a resolution at an annual or special general meeting if the expenditure crosses the threshold set in the Strata Property Act or the strata’s own bylaws, and owners will want to see how it’s funded: contingency reserve fund, a special levy, or financing. We provide the kind of written scope and cost-factor breakdown that a council can actually bring to an AGM — what’s being replaced, why, the sequence of work, and the disruption residents should expect — rather than a vague verbal estimate that doesn’t hold up to owner questions. If your building has had a depreciation report or reserve fund study done, that document usually already flags mechanical system age and expected replacement windows; we’re glad to review it alongside our own inspection findings so the council isn’t working from two disconnected sets of numbers. Property managers are often the day-to-day point of contact, but final authority sits with the council and, for larger spends, the ownership — we build our proposals to move cleanly through that chain rather than needing rework at each stage.

Phased replacement: avoiding a building-wide shutdown

Replacing a central boiler plant or a domestic hot water system in an occupied building is not a single-day job, and treating it like one is how you end up with two hundred angry residents and no hot water for a week. The standard approach is phasing: bring in temporary or partial capacity if the plant design allows it, replace one boiler in a multi-boiler plant while the others carry the load, or schedule the cutover for a low-demand period and complete it in a compressed window with backup heat staged and ready. For hot water systems, that can mean installing and commissioning a new tank or heat exchanger in parallel with the old one before switching over, so there’s no gap at all. None of this happens without real planning — confirming crane or hoisting access if equipment has to move through a mechanical room door that’s smaller than the new unit, checking gas line capacity if load is increasing, and coordinating with the building’s own maintenance staff or the property manager on notice to residents. We build a written schedule for the strata that shows what’s happening on which day, what services (if any) are interrupted and for how long, and what the fallback plan is if something takes longer than expected. Council and property managers use that document to communicate with owners directly, which cuts down enormously on the phone calls asking what’s going on halfway through a project.

Maintenance contracts versus reactive service

A lot of multi-family buildings run on reactive service by default — nobody calls until something fails — and that works fine right up until a plant failure lands in the middle of a cold snap with residents in every unit affected at once. A standing maintenance agreement changes the math: scheduled inspections catch a failing pump seal, a drifting control setpoint, or early corrosion on a heat exchanger while it’s still a planned repair instead of an emergency call. For a council weighing the cost of a contract against the cost of reactive calls, the honest answer is that it depends on the building’s equipment age, size, and history — a newer plant with a strong service record needs less frequent attention than a system already fifteen years into a twenty-year expected lifespan. We’re upfront about that rather than pushing a maintenance plan as a blanket recommendation for every building. What we can say generally is that a documented maintenance history is useful beyond just catching faults early — it’s something future councils, buyers doing due diligence, and insurers may ask to see, and a building with gaps in that record is harder to make decisions about later. If your strata already has a maintenance provider and just needs a second opinion on a specific fault or an upcoming replacement decision, that’s a normal ask and doesn’t require displacing an existing contract.

Coastal Lower Mainland factors that affect these systems

Buildings here deal with a specific set of conditions that inland climates don’t. Damp coastal winters mean mechanical rooms and rooftop equipment enclosures are exposed to sustained moisture for months at a stretch, and any building within a few kilometres of salt water — which covers a lot of Metro Vancouver’s waterfront strata developments — sees accelerated corrosion on exposed metal components, fasteners, and venting compared to the same equipment inland. That’s a maintenance planning factor, not a reason to avoid particular equipment, but it does mean inspection intervals for corrosion-prone components are worth taking seriously in these locations. Older Lower Mainland housing stock is another factor: a lot of the region’s mid-rise stratas were built in the 1970s through 1990s, often with mechanical systems designed to codes and standards that have since changed, and boiler rooms sized for equipment that’s smaller and more efficient than what was standard at the time of construction — which sometimes constrains what can physically be installed as a replacement without room modifications. Strata rules and municipal permits add another layer: outdoor equipment like exterior make-up air intakes or any rooftop unit replacement often needs to account for strata bylaw restrictions on rooftop access, noise limits tied to municipal bylaws, and the relevant municipality’s permit requirements before work starts. We factor all of this into scoping rather than treating it as a surprise partway through a project.

Permits, TSBC gas certification, and working with property managers

Any gas-fired boiler or water heating equipment in a strata building falls under the same TSBC (Technical Safety BC) gas certification requirements as residential gas work, and for equipment at the scale of a central plant, that oversight is not optional paperwork to skip — it’s the standard your strata’s insurer and the municipality both expect to see documented. We carry that certification and pull the permits required for boiler and gas water heater work; a strata council or property manager asking to see proof of that before work starts is asking a reasonable question, and we provide it without friction. Municipal permitting requirements vary by city across the Lower Mainland, and larger mechanical replacements typically need sign-off beyond just the gas permit — mechanical and sometimes electrical permits depending on scope. Property managers are usually the ones coordinating permit applications, building access for contractors, and resident notices, so a clean working relationship with the management company speeds up a project considerably; a fragmented one where every access request has to go through three people slows it down just as much. If you smell gas anywhere in a building — a suite, a corridor, or the mechanical room — the standing safety rule applies regardless of building type: leave the area, get others out, and call the gas utility and a licensed gas technician from outside the building. That’s not a judgment call to make on-site.

What a site assessment involves and when to call

For a strata considering repair versus replacement, or just wanting a clear picture of where the plant and hot water system actually stand, the starting point is a site visit rather than a phone estimate. That means walking the mechanical room, checking equipment nameplates and install dates against what documentation the strata has on file, testing operating pressures and temperatures against manufacturer specifications, and looking at venting, combustion air, and general condition — corrosion, leaks, signs of past repairs that may not have been logged anywhere. For hot water systems specifically, that includes checking recirculation balance and tank or heat exchanger condition. We put findings in writing: what’s functioning normally, what’s showing early wear worth watching, and what needs action now, each with enough detail that a council can bring it to a board meeting or an AGM without needing us there to explain it verbally. No pricing gets quoted off a phone call for work at this scale — costs depend on what’s actually found, access conditions, and current equipment availability, so we don’t put a number on anything sight unseen. If your building already has a depreciation report flagging mechanical system age, bring it to the site visit; it saves time and lets us confirm or update those projections against current condition rather than working from two separate assessments that might not agree.

Quick Checklist

• Confirm whether HVAC/hot water/corridor heating falls under strata or individual owner responsibility in your bylaws
• Pull any existing depreciation report or reserve fund study before the site visit
• Ask the property manager for whatever mechanical drawings or service history the strata has on file
• Get a written scope and cost-factor breakdown before bringing a project to an AGM or special resolution
• Confirm the contractor holds current TSBC gas certification for any gas-fired equipment
• Ask specifically how a proposed repair or replacement will be phased to avoid a full building outage
• Check access constraints early — mechanical room door sizes, crane or hoisting needs, parkade clearance
• Confirm which municipal permits apply to the scope before work is scheduled
• Build a resident notice plan alongside the contractor’s work schedule, not after it’s finalized
• Review corrosion and moisture exposure risk if the building is near open water or exposed rooftop equipment
