Furnace Comparison
Lennox vs Trane Furnace: Which Is Right for Your Metro Vancouver Home?
Lennox's SLP99V (up to ~99% AFUE) is one of the highest-efficiency gas furnaces sold residentially, edging out Trane's S9V2 on peak published efficiency. Trane counters with a strong reputation for cabinet durability and long service life. For most Metro Vancouver homes the practical gap is small — CANRO sizes both properly and gives an honest comparison based on your ductwork and budget.

CANRO’s honest take
Lennox's SLP99V (up to ~99% AFUE) is one of the highest-efficiency gas furnaces sold residentially, edging out Trane's S9V2 on peak published efficiency. Trane counters with a strong reputation for cabinet durability and long service life. For most Metro Vancouver homes the practical gap is small — CANRO sizes both properly and gives an honest comparison based on your ductwork and budget.
Both Lennox and Trane are established, well-supported brands with strong residential furnace lineups — CANRO installs and services both across Metro Vancouver. Rather than declaring a universal "winner," we size your home properly and recommend the model (from either brand) that actually fits your ductwork, budget, and comfort goals.
Lennox vs Trane FAQs
Is Lennox or Trane better for a Metro Vancouver home?+
Both are well-supported, high-quality brands and CANRO installs and services both. The right choice usually comes down to your existing ductwork, budget, and whether you want to match an existing system rather than one brand being objectively "better" for every home.
Do Lennox and Trane qualify for the same rebates?+
Qualifying high-efficiency furnaces from both brands are generally eligible for the same CleanBC/BC Hydro/FortisBC programs — eligibility is based on the specific model’s efficiency rating, not the brand name. CANRO confirms eligibility before quoting.
Can CANRO install and service both Lennox and Trane?+
Yes — CANRO is a licensed installer and servicer for both brands (and most other major residential HVAC brands) across Metro Vancouver.
How do I decide between them for my home?+
CANRO performs a proper load calculation and reviews your existing ductwork/electrical/gas setup, then gives an honest recommendation and written quote for the model that best fits — rather than defaulting to one brand.

Frequently asked questions
How often should a furnace be serviced?
Annual servicing is recommended for gas furnaces, ideally before the start of the heating season in September or October. Service includes burner cleaning, heat exchanger inspection, ignition check, blower motor cleaning, gas pressure adjustment and a full safety test for carbon-monoxide leaks.
How long does a furnace last in Vancouver's climate?
High-efficiency gas furnaces typically last 15–20 years with annual maintenance. Vancouver's mild climate means lower run-times than colder Canadian cities, which extends life — but salt-air corrosion near the coast and high humidity can shorten it.
Why is my furnace blowing cold air?
Common causes are a thermostat set to "on" instead of "auto", a tripped flame sensor, a clogged condensate drain shutting down a high-efficiency unit, low gas pressure, or a failed ignitor. Most are repairable in a single service visit.
How much does a new furnace cost in Vancouver?
A typical residential high-efficiency gas furnace in Metro Vancouver costs $4,500–$8,500 installed depending on size, brand and venting requirements. Variable-speed and modulating models are at the upper end.
What is the most reliable furnace brand?
In our experience servicing Vancouver homes since 1999, Carrier, Lennox, Bryant and York have produced the most reliable mid-to-high-efficiency furnaces with the best parts availability. Goodman and Rheem offer strong value at lower price points.
