safely and effectively. Our
licensed and Red Seal-certified technicians are trained to

Signs of a Furnace Gas Leak
Natural gas is odorless, but
gas suppliers add a sulfur-like smell (rotten eggs) to help detect leaks. Here are key warning signs:
✔
Rotten Egg Smell – If you smell sulfur or rotten eggs near your furnace,
turn off the gas supply and leave the house immediately.
✔
Hissing or Whistling Sounds – A
leaking gas line or valve may produce a
hissing noise near the furnace.
✔
Unusual Furnace Flames – A
yellow or flickering pilot light instead of blue may indicate
incomplete combustion and a gas leak.
✔
Physical Symptoms – Exposure to
natural gas or carbon monoxide can cause
dizziness, headaches, nausea, and shortness of breath.
✔
Increased Gas Bills – A sudden spike in
gas consumption could mean your furnace is leaking gas.
✔
Dead or Dying Houseplants – Gas leaks
displace oxygen, which can cause
plants to wilt or die unexpectedly.
What to Do If You Suspect a Furnace Gas Leak
A
gas leak is an emergency—take these
immediate steps:
- Evacuate Everyone – Leave the house immediately without using electrical devices, light switches, or appliances.
- Shut Off the Gas Supply – If safe to do so, turn off the main gas valve to stop the leak.
- Do Not Ignite Flames – Avoid smoking, lighting candles, or using open flames.
- Call Emergency Services & CANRO Heating & Cooling – Contact FortisBC at 1-800-663-9911 and call CANRO Heating & Cooling at 604-359-1081 for emergency repair.
- Ventilate the Area – Open windows and doors to allow gas to disperse.
Common Causes of Furnace Gas Leaks
Gas leaks in furnaces are often caused by
wear and tear, poor maintenance, or faulty components. Here are the most common culprits:
1. Cracked Heat Exchanger
- The heat exchanger transfers heat to the air while keeping combustion gases separate.
- Cracks in the exchanger can cause gas leaks and carbon monoxide exposure.
2. Faulty Gas Valve or Gas Line Connection
- Loose or damaged gas valve fittings may leak natural gas into your home.
- Older gas lines can develop corrosion and cracks, leading to dangerous leaks.
3. Malfunctioning Pilot Light or Ignition System
- A weak or flickering pilot light could indicate gas flow issues.
- A failing ignition system may not properly control gas flow, increasing the risk of leaks.
4. Worn-Out Furnace Components
- Over time, gaskets, seals, and connectors wear out, leading to small gas leaks that worsen if left untreated.
5. Poor Furnace Installation
- Incorrectly installed gas lines, regulators, or vents can cause gas leaks and improper combustion.
- Always hire a certified HVAC contractor like CANRO Heating & Cooling to ensure safe furnace installation.

Expert insights: furnaces in Metro Vancouver
Selecting and servicing furnaces in Metro Vancouver involves several local factors — climate, available rebates, code requirements — covered below. 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.
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 furnace systems across Metro Vancouver since 1999, including installations and service calls in White Rock, Capitol Hill, Norgate and Lynn Valley.
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.
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

Furnace FAQs
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.
Do I really need annual furnace servicing in Vancouver?
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 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?
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?
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.
