A new high-efficiency furnace pays back through gas savings + rebate. The exact payback depends on what youre replacing and how much you heat.

Old unit: 80% AFUE atmospheric, $1,700/year gas. New unit: 96% AFUE two-stage, $1,400/year gas. Annual savings: $300. Install cost: $6,500 (after $500 rebate). Simple payback: 22 years (just on savings alone).
You were going to replace eventually anyway. The real comparison is "replace now" vs "replace in 3 years after another major repair":
Replace now: $6,500 + ($1,400 × 15 years gas) + $500 future repairs = $28,000 over 15 years.
Replace in 3 years: $1,500 current repair + $1,700 × 3 yrs gas + $6,500 install in year 4 + $1,400 × 12 yrs future gas + future repairs = ~$28,500. Replace-now wins slightly.
(1) Replacing oil heat with gas: saves $1,500-$3,000/year. Payback under 5 years. (2) Going from old 60-70% AFUE to 96%: saves $400-$600/year. Payback 8-12 years. (3) Pairing furnace replacement with insulation upgrades: combined savings 30%+.
(1) Replacing a 90% AFUE unit with 96% — only 6% gain. (2) Small home with low heating use. (3) Moving in 1-2 years.
For homes with high heating use, hybrid heat pump + gas furnace cuts gas use 60-80% while keeping cold-day reliability. Combined with FortisBC + BC Hydro rebates, can be cheaper than a pure furnace replacement. Worth quoting.

Metro Vancouver homes have specific requirements when it comes to furnaces, driven by climate, code, and the local housing stock. This page covers the essentials. A modern high-efficiency gas furnace in Metro Vancouver operates at 95-98% AFUE, modulating its burner output between 40% and 100% to match demand. Vancouver's mild climate means short, frequent run cycles, which favours variable-speed ECM blowers and two-stage or modulating gas valves.
Vancouver's mild winters (average lows above -5°C and rare deep cold snaps) shape equipment selection differently than colder Canadian cities. CANRO has worked with furnace systems across Metro Vancouver since 1999, including installations and service calls in Burnaby Heights, West End, Edgemont and Brighouse.
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.
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.
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.
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.
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.
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 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.
