CANRO Heating & Cooling – Greater Vancouver’s trusted HVAC experts! Expert insights: Lennox HVAC systems in Metro Vancouver
What follows is the practical information CANRO shares with Metro Vancouver homeowners about HVAC systems during in-home consultations. Lennox is American (Iowa, 1895), best known for its SLP99V variable-capacity gas furnace (up to 99% AFUE) and the XC25 air conditioner. The brand's strengths are industry-leading variable-capacity modulation, premium build quality, top-rated for quiet operation.
Heat-pump rebates from BC Hydro, FortisBC and the federal Greener Homes program stack to as much as $11,000+ for eligible Metro Vancouver households, dramatically changing the install-cost math vs. a conventional system. CANRO has worked with Lennox systems across Metro Vancouver since 1999, from older retrofits in Ladner and Capitol Hill to new builds in Pitt Meadows and South Surrey. Lennox is generally a strong fit for mid-to-upper Vancouver homes wanting maximum efficiency and the quietest possible system.
Technical considerations for HVAC systems in Metro Vancouver
Sizing. Right-sized HVAC equipment delivers comfort, efficiency, and long lifespan. Over-sized equipment short-cycles; under-sized equipment runs constantly and fails early.
Lifespan. Most modern HVAC equipment lasts 12-20 years in Vancouver's mild climate. Annual maintenance is the single biggest factor in extending lifespan and preventing emergency failures.
Warning signs. Common HVAC warning signs: rising energy bills, uneven heating/cooling, unusual noises, persistent error codes, frequent on-off cycling, or visible condensation on registers.
Common Lennox HVAC system issues CANRO diagnoses
Over 25+ years of Lennox service calls across Metro Vancouver, the recurring issues we see are: flame-sensor fouling on older units, control-board failures on iComfort thermostats, blower-wheel ECM motor failures.
Parts availability. Lennox parts are dealer-network only — independent shops often struggle to source within 48 hours, but CANRO maintains a Lennox parts pipeline.
What CANRO checks during a HVAC system service
- Full system safety inspection
- Annual maintenance per equipment type

Lennox Hvac system FAQs
Are your technicians licensed and insured?
Yes. CANRO holds a TSBC Class-A gas-fitting licence, our technicians are Red Seal certified for HVAC, and we carry full liability insurance plus WorkSafeBC coverage.
How often should HVAC equipment be serviced?
Annual servicing is recommended for every gas-fired appliance (furnace, boiler, hot-water tank, fireplace) and every cooling system (A/C, heat pump). Annual maintenance is also required to keep most manufacturer warranties valid.
How long does HVAC equipment last in Metro Vancouver (Lennox)?
Typical service life with annual maintenance: gas furnace 15-20 years, gas boiler 15-20 years (cast-iron 25-30), heat pump 15-20 years, central A/C 12-15 years, hot-water tank 8-12 years, tankless water heater 18-22 years, gas fireplace 20-30 years.
What HVAC services do you offer?
CANRO provides installation, repair, annual servicing and parts replacement for boilers, gas furnaces, heat pumps, hot-water tanks, tankless water heaters, gas fireplaces, central air conditioning, ductless mini-splits and gas-fitting services across Metro Vancouver.
How do I know when to repair vs replace HVAC equipment?
General rule: if the equipment is more than 75% of its expected life AND the repair cost is more than 50% of replacement, replacement is usually the better investment because new high-efficiency equipment pays back the difference in energy savings over 5-10 years.
Do you service strata buildings and condos in Vancouver (Lennox)?
Yes. CANRO works with stratas across Metro Vancouver on common-area HVAC (boilers, makeup-air units, A/C towers) and in-suite systems. We provide signed work orders and detailed invoicing suitable for strata reporting and reserve-fund planning.
