Understanding Key Lennox Furnace Components and Common Issues
Lennox furnaces are engineered for top performance, but like all HVAC systems, certain parts may experience wear and tear over time. Let’s take a closer look at these key components and the role each plays in your furnace’s operation:
1. Lennox Furnace Draft Inducer Motor
The draft inducer motor is responsible for creating negative pressure in the heat exchanger, which allows the safe and efficient venting of combustion gases. It ensures that gas is drawn away from the furnace and vented outdoors, preventing carbon monoxide buildup inside your home.
- Common Issues: A worn-out or noisy draft inducer motor may cause operational inefficiencies or prevent the furnace from igniting.
- Signs of Problems: If you hear unusual noises, experience ignition delays, or notice reduced heating efficiency, the inducer motor may need attention.
2. Lennox Furnace Exhaust Fan Motor
The exhaust fan motor works alongside the inducer motor to expel combustion gases from the furnace, ensuring proper airflow through the heating system. This component is critical for both safety and efficiency, as it prevents harmful gases from lingering within the system.
- Common Issues: Exhaust fan motors can wear out or become blocked, impacting furnace efficiency and potentially causing dangerous gas buildup.
- Signs of Problems: Poor air circulation, increased energy bills, or a burning smell can indicate issues with the exhaust fan motor.
3. Lennox Furnace Heat Exchanger
The heat exchanger is responsible for transferring heat from combustion gases to the air that circulates through your home. It keeps dangerous gases contained while allowing heat to disperse into the living space safely.
- Common Issues: Cracks in the heat exchanger can lead to carbon monoxide leaks, posing serious health risks.
- Signs of Problems: Rattling noises, soot buildup, or a yellow furnace flame are signs of potential heat exchanger issues.
4. Lennox Furnace Inducer Motor
The inducer motor is essential for starting the heating cycle, as it removes any leftover combustion gases and ensures a clean and safe environment for the next ignition cycle. This motor creates draft pressure to push gases out through the vent system.
- Common Issues: If the inducer motor fails, the furnace may not start, and carbon monoxide buildup may occur.
- Signs of Problems: Loud noises at startup, ignition failures, or error codes can signal inducer motor problems.

Expert insights: Lennox boilers in Metro Vancouver
Metro Vancouver homes have specific requirements when it comes to boilers, driven by climate, code, and the local housing stock. This page covers the essentials. 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.
Vancouver's moderately hard tap water (around 60-100 ppm hardness in most of Metro Vancouver) affects tankless water heaters, combi boilers, and hot-water tanks — annual descaling is essential. CANRO has worked with Lennox systems across Metro Vancouver since 1999, from older retrofits in Norgate and Maillardville to new builds in Thompson and Metrotown. Lennox is generally a strong fit for mid-to-upper Vancouver homes wanting maximum efficiency and the quietest possible system.
Technical considerations for boilers in Metro Vancouver
Sizing. Boiler sizing depends on heat-loss calculations (Manual J for the home + emitter capacity check). Oversized boilers short-cycle, which is the single biggest cause of premature heat-exchanger failure in Vancouver hydronic installs.
Lifespan. A well-maintained condensing boiler typically lasts 15-20 years in Vancouver. Cast-iron heritage boilers can run 30+ years, but their efficiency (60-75% AFUE) often makes replacement worthwhile after 20 years on energy savings alone.
Warning signs. A failing boiler typically shows kettling (banging or whistling at start-up), expansion-tank pressure loss requiring frequent top-ups, sooty combustion residue, persistent error codes, or radiators that no longer balance.
Common Lennox boiler 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 boiler service
- Combustion analysis at low fire and high fire
- Heat-exchanger inspection (scale, soot)
- Expansion-tank pressure check and pre-charge
- Pressure-relief valve operation
- Circulator pump amp draw and bearing check
- Condensate trap and neutraliser inspection
- Gas-valve modulation test
- Igniter and flame-rod inspection
- Air separator and check valves
- System fill-pressure and air-purge

Lennox Boiler FAQs
My boiler keeps losing pressure — what's wrong?
Pressure loss indicates either: an expansion tank that has lost its air charge, a leak somewhere in the loop (often a tiny pinhole behind a radiator or under flooring), a weeping pressure-relief valve, or a faulty automatic fill valve. CANRO uses pressure-decay testing and infrared imaging to locate hidden leaks.
What is kettling — that banging sound from my boiler?
Kettling is a banging or whistling sound caused by limescale build-up on the heat exchanger, which creates localised overheating spots. It will not always cause immediate failure but it shortens boiler life significantly and should be addressed within a few weeks by descaling and water-chemistry correction.
How often should a boiler be serviced?
Annual servicing is recommended for all residential boilers in Metro Vancouver. The service includes combustion analysis, heat-exchanger inspection, expansion-tank pressure check, condensate-trap cleaning, circulator pump check, and a full safety inspection. Annual maintenance is also required to keep most manufacturer warranties valid.
Should I repair or replace my 15-year-old boiler?
A useful rule: if the boiler is more than 15 years old and the repair cost is more than 50% of replacement, replacement is the better long-term investment because newer units run at 95%+ AFUE vs 75-82% for older models — paying back the difference in energy savings over 6-10 years. CANRO gives you both quotes and lets you decide.
How much does a new boiler cost in Metro Vancouver (Lennox)?
A typical residential high-efficiency gas boiler installation in Metro Vancouver costs $7,500-$15,000 depending on size, brand, and whether the system is heating-only or a combi unit also handling domestic hot water. Premium European brands (Viessmann, Baxi) sit at the upper end; North American brands (Navien, IBC, Rinnai) at the lower-middle.
What's the difference between a heating-only boiler and a combi?
A heating-only boiler heats only the hydronic loop (radiators, in-floor radiant, air-handler coil); a separate hot-water tank handles domestic hot water. A combi (combination) boiler heats both — eliminating the tank but requiring a higher-BTU boiler to handle peak DHW demand. Combi installs work best for 1-3 bathroom homes; heating-only + tank is usually better for 4+ bathroom homes.
