Lochinvar and Laars are both established North American boiler manufacturers whose residential lines span standard-efficiency and condensing models, so the better fit usually comes down to your home's venting layout and a technician's local familiarity with the specific line.

Quick answer
Both Lochinvar and Laars build a range of gas-fired boilers that cover conventional atmospheric designs as well as higher-efficiency condensing models, so neither brand can be called the automatic choice for every home. The more useful comparison is how each line handles heat exchanger material, venting requirements, and whether a technician working in the Lower Mainland services that specific series regularly. A licensed gas fitter who inspects your existing venting, gas supply, and mechanical room space will generally give you a more reliable answer than a spec sheet comparison alone.

Lochinvar has a long history supplying gas-fired boilers across North America, with model lines that span standard-efficiency atmospheric designs and higher-efficiency condensing units built around stainless steel heat exchangers. The stainless construction in the condensing tier is commonly documented as more resistant to the mildly acidic condensate that high-efficiency combustion produces, though the exact alloy and warranty terms vary by specific model and should be verified against the manual and certificate for the unit installed.
Laars has a long-standing presence on the West Coast, including British Columbia, with a lineup that similarly covers both conventional and condensing designs. Where Laars tends to differ in practice is in how its lineup has historically leaned toward straightforward mechanical room installations, which some technicians find easier to retrofit into an existing venting configuration without major changes to the flue run.
Condensing models from either brand extract additional heat from the flue gases before they exit the home, which generally means a lower flue-gas temperature and, correspondingly, a plastic or stainless venting material rather than a traditional metal chimney liner. Non-condensing or standard-efficiency models from both manufacturers typically still rely on a conventional metal vent or an existing masonry chimney, which matters a great deal if your home already has one in place.
Because efficiency tier changes the venting requirement more than the brand name does, the real decision point for a lot of Metro Vancouver homeowners is whether they want to keep an existing chimney in service or convert to sidewall venting during the swap. That conversion is a mechanical decision a licensed technician needs to walk through on-site, not something a brand comparison alone can settle.
| Factor | Lochinvar | Laars |
|---|---|---|
| Efficiency range offered | Standard-efficiency through condensing | Standard-efficiency through condensing |
| Condensing heat exchanger material | Commonly documented as stainless steel | Varies by series, verify against manual |
| Typical venting fit | Depends on model tier | Often suited to simpler retrofit venting |
| Local parts familiarity | Common among Lower Mainland wholesalers | Long-standing West Coast presence |
| Best general fit | Homes wanting a wide model range | Homes prioritizing simpler mechanical retrofits |
A hillside home on the North Shore often has a mechanical room tucked into a daylight basement with a longer run to an exterior wall or an existing chimney chase built into the original construction. In that layout, whichever brand's condensing model uses a venting configuration compatible with the existing chase, without expensive rerouting, is usually the more practical choice, and that's a site-specific answer rather than a brand-wide one.
Homes on a slope also tend to have more exposed exterior wall for a sidewall vent termination, which can make a condensing conversion from either brand more straightforward than in a rowhouse with limited exterior wall access. A technician who has actually walked the mechanical room can tell you which brand's vent kit fits that specific chase or wall run with the least modification.
Both brands offer wall-hung and floor-standing configurations depending on the model, so mechanical room floor space versus wall space available should be measured before comparing brands at all. A floor-standing unit from either manufacturer generally needs more clearance around the base for service access, while a wall-hung condensing unit can free up floor space in a tight utility room.
Gas line sizing and combustion air supply also need to be checked against the specific model's input rating, since a larger-capacity unit from either brand may require a larger gas line or dedicated combustion air intake than an older, smaller boiler being replaced. This is part of the load calculation a licensed technician performs before recommending either brand.
Lochinvar's distribution through HVAC wholesalers across the Lower Mainland means technicians who work on the brand regularly can typically source common parts without long delays, though lead times for less common components can still vary by season and supplier stock.
Laars parts availability locally tends to depend on how long the specific unit has been in service and whether the exact series is still in active production, so an older Laars boiler may need a technician to check parts availability before committing to a repair versus a full replacement. Warranty terms are set entirely by the manufacturer and should be confirmed against the certificate issued at installation, not assumed from the brand name.
Annual maintenance on either brand typically includes a combustion analysis, a check of the heat exchanger and venting for corrosion or blockage, a condensate drain inspection on condensing models, and a review of the safety controls and ignition system. A technician who documents these checks over successive years, regardless of brand, is what actually protects you against a surprise mid-winter failure, not the manufacturer's name on the jacket.
When a boiler from either brand is more than a decade old and starts needing repeat repairs, particularly around the heat exchanger or ignition system, a licensed technician can walk you through whether continuing to repair the existing unit still makes sense or whether replacement is the better long-term value. Boiler replacement in the Lower Mainland generally runs in the $7,500 to $15,000-plus range as a ballpark, not a quote, with the final number depending on venting changes, gas line work, and the specific model selected.
Safety note
If you ever smell gas near a boiler, hear it hissing, or a carbon monoxide alarm sounds, leave the home immediately and call FortisBC at 1-800-663-9911 from outside before doing anything else. Any gas boiler work, including swapping brands, must be done by a Technical Safety BC licensed gas fitter.
Both brands have a long-standing presence in the region, and local availability tends to depend more on which wholesalers a given contractor works with than on one brand being universally more common than the other.
Sometimes, but it depends on whether the existing vent material and diameter are compatible with the new unit's efficiency tier. A licensed technician needs to inspect the existing venting before confirming this.
Yes. Condensing boilers from any manufacturer produce acidic condensate that needs a proper drain, and in some cases a neutralizer, which should be part of the installation plan regardless of brand.
Warranty terms are set by each manufacturer and can change by model year, so this should be verified against the certificate issued for your specific unit rather than assumed from general brand reputation.
Price is one factor, but venting compatibility, mechanical room space, and a technician's familiarity with the specific line usually matter more for long-term reliability than the sticker price difference between two comparable models.
