When Should You Schedule Furnace Maintenance?
To keep your Lennox furnace in top condition, it’s recommended to schedule professional maintenance at least once a year. Ideally, this should be done in the fall before the heating season begins, ensuring your system is ready to handle the demands of winter.

Expert insights: Lennox furnaces in Metro Vancouver
What follows is the practical information CANRO shares with Metro Vancouver homeowners about furnaces 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 Eagle Ridge and Edgemont to new builds in Yaletown and Guildford. Lennox is generally a strong fit for mid-to-upper Vancouver homes wanting maximum efficiency and the quietest possible system.
Technical considerations for furnaces in Metro Vancouver
Sizing. Proper furnace sizing requires a Manual J load calculation — most Vancouver homes need 50,000-90,000 BTU, but oversized furnaces short-cycle, accelerate component wear and produce uneven temperatures.
Lifespan. A well-maintained high-efficiency gas furnace lasts 15-20 years in Vancouver. The single biggest factor in lifespan is annual professional servicing — combustion analysis, condensate trap cleaning, and igniter inspection prevent 80% of mid-life failures.
Warning signs. A failing furnace usually announces itself: short-cycling, yellow flame (should be blue), rising gas bills, uneven heating between rooms, banging on startup, or persistent error codes on the control board.
Common Lennox furnace 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 furnace service
- Combustion analysis (CO, CO2, O2, stack temperature)
- Heat-exchanger inspection (cracks, corrosion)
- Flame sensor cleaning
- Hot-surface ignitor test
- Gas pressure verification (inlet + manifold)
- Condensate trap and drain clearing
- Blower motor amp draw and bearing check
- Filter replacement and airflow verification
- Limit switch and rollout safety test
- Thermostat calibration and response check

Lennox Furnace FAQs
Do I really need annual furnace servicing in Vancouver (Lennox)?
Yes. Annual professional servicing catches 80% of mid-life failures before they cause a no-heat call. It also keeps manufacturer warranties valid — most are voided by missing scheduled maintenance. The service includes combustion analysis, heat-exchanger inspection, flame-sensor cleaning, blower-motor check, condensate-trap clearing, and a full safety test for carbon monoxide.
What AFUE rating should I look for in a new Vancouver (Lennox) furnace?
For Metro Vancouver homes, 95-97% AFUE is the sweet spot — high enough to qualify for FortisBC rebates and capture nearly all available efficiency gains, but without paying a premium for the very last 1-2% from 98% AFUE modulating units. ENERGY STAR-certified models above 95% AFUE are required for current rebate programs.
Two-stage vs modulating gas furnace — what's right for Vancouver (Lennox)?
Two-stage furnaces (high/low burner) are a good fit for most Vancouver homes — they cut short-cycling and run quieter than single-stage units. Modulating furnaces (continuously variable burner output) are worth the premium in larger homes (3,000+ sq ft), homes with significant temperature zones, or homes prioritising the absolute quietest operation.
How much does furnace installation cost in Metro Vancouver (Lennox)?
A typical residential high-efficiency gas furnace installation in Metro Vancouver costs $4,500-$8,500 including the equipment, venting, gas-line work, permit, electrical, and removal of the old unit. Variable-speed and modulating models are at the upper end. CANRO provides three quote tiers (good/better/best) so you can choose the right balance for your home and budget.
Can I install a heat pump and skip the furnace altogether?
Yes — for most Metro Vancouver homes, a cold-climate heat pump alone provides 100% of heating needs down to -10°C. Some homeowners choose a dual-fuel setup (heat pump + small gas furnace as back-up for the rare deep cold snap), but this is rarely necessary in our climate.
Why does my furnace short-cycle (turn on and off rapidly)?
Short-cycling typically indicates one of: an over-sized furnace for the home, a dirty flame sensor, a clogged condensate drain triggering shutdown, low gas pressure, a failing limit switch, or a thermostat located in a non-representative spot (in direct sunlight, near a vent). All are diagnosed quickly during a service call.
