Lennox Furnace Installed Prices in Canada — Quick Answer
Prices verified August 2026. All figures are installed costs in CAD and include equipment, labour, standard venting, Ontario TSSA permit, and removal of the old furnace. Homes requiring gas line work, chimney liner replacement, or significant ductwork modification will see higher totals.
What Affects the Installed Cost of a Lennox Furnace?
No two furnace installations are identical. These are the main variables that move the installed price up or down:
Merit vs. Elite vs. Signature — Which Lennox Line Is Right for You?
Lennox Merit ML196E — Entry-Level, 96% AFUE
The ML196E is Lennox’s entry-level high-efficiency gas furnace. It runs at 96% AFUE in single or two-stage operation using a constant-torque PSC blower motor. Available in 30,000–120,000 BTU configurations. It meets Ontario’s minimum 95% AFUE requirement and earns ENERGY STAR certification. Installer note: the ML196E is reliable and straightforward to service. It’s the right call for rental properties, older homes with decent insulation, or any situation where the budget is the primary constraint. It’s not the right call for a 2,500 sq ft home where the homeowner will notice uneven temperature distribution or blower noise.
Lennox Elite EL296E / EL297V — Mid-Range, 96–97% AFUE
The EL296E runs at 96% AFUE with two-stage heat and a constant-torque blower. The EL297V steps up to 97% AFUE with a variable-speed ECM blower motor that ramps output up or down continuously based on demand — significantly reducing blower noise and improving comfort. Both are two-stage on the heating side. Installer note: the EL297V is the most common furnace we install in GTA detached homes. The variable-speed blower is quieter, distributes heat more evenly, and runs more efficiently at partial load. For most homeowners choosing between the EL296E and EL297V, the EL297V is worth the modest price difference.
Lennox Signature SLP99V — Premium, Up to 99% AFUE
The SLP99V is the top of the Lennox Signature Collection. It runs at up to 99% AFUE — the highest AFUE rating in the Lennox residential furnace lineup. The modulating gas valve adjusts the burner in increments as small as 1% of full capacity. Combined with a fully variable-speed ECM blower, it is the quietest, most efficient Lennox furnace available. It integrates natively with the Lennox iComfort S30 smart thermostat for zoning and remote monitoring. Installer note: the SLP99V is genuinely the best Lennox furnace for homes over 2,000 sq ft where comfort and quiet operation matter. The higher installed cost is real — [TEAM TO ADD INSTALLER NOTES HERE] — but the long-term operating cost savings are also real in homes that run the furnace hard through a GTA winter.
Two-Stage and Variable-Speed Furnaces Explained
Single-stage furnaces are either fully on or fully off. When the thermostat calls for heat, the burner fires at 100% and the blower runs at full speed. This creates the “blast of hot air” effect most GTA homeowners are familiar with from older systems.
A Lennox 2-stage furnace (EL296E, EL297V) has two firing rates: a low stage (typically 65–70% of full output) and a high stage (100%). On most GTA days, the furnace runs in low stage — longer, quieter cycles that distribute heat more evenly. High stage only kicks in during the coldest stretches.
A Lennox variable-speed furnace (SLP99V) uses a modulating burner that adjusts output continuously, combined with a variable-speed blower that does the same. The result is near-silent operation at partial load, the most even heat distribution, and the lowest operating cost. The SLP99V rarely runs at full capacity except on the coldest January nights.
When the upgrade is worth it: if you have a home over 1,800 sq ft, multiple zones, or you notice uneven temperatures or blower noise from your current furnace, a two-stage or variable-speed model will make a noticeable difference. For a 900 sq ft condo or small bungalow, the single-stage ML196E does the job.
Our Verdict as Lennox Installers
Lennox furnaces are well-engineered, well-warranted, and well-supported through the dealer network. As an authorized Lennox Premier Dealer, we install all three lines regularly and see the long-term performance across different GTA home types.
Ontario Furnace Rebates — What’s Actually Available in 2026
There is currently no Ontario government rebate for gas furnace replacement. The Canada Greener Homes Grant closed to new applications in 2024 and did not cover gas furnace-only replacements. The Home Renovation Savings Program covers some heat pump and insulation work but not standalone gas furnace installations.

If you’re considering pairing a new furnace with a Lennox heat pump, that combination may qualify for available incentives — ask us during your quote visit.

Frequently Asked Questions
How much does a Lennox furnace cost installed in Canada?
Installed costs in Canada (CAD) typically range from approximately $5,500 to $11,000+ depending on the model line and site conditions. The Merit ML196E sits at the lower end; the Signature SLP99V sits at the upper end. These are fully installed prices covering equipment, labour, Ontario TSSA permit, standard venting, and removal of the old furnace. Exact pricing requires a free in-home assessment.
Which Lennox furnace model is best?
For most GTA homes between 1,500 and 2,500 sq ft, the Lennox Elite EL297V (97% AFUE, variable-speed) is our most recommended model. It balances installed cost, long-term efficiency, and comfort. Larger homes or homeowners prioritising maximum efficiency should consider the SLP99V. Smaller homes or budget replacements are well-served by the ML196E.
Are Lennox furnaces reliable?
Yes. As a Lennox Premier Dealer we service the equipment we install. Lennox furnaces have a strong reliability record across all three lines when professionally installed and maintained annually. The heat exchanger warranty — lifetime on the SLP99V, 20 years on other models — reflects Lennox’s confidence in the core component.
What’s the difference between Merit, Elite and Signature?
Merit is single or two-stage, 96% AFUE, constant-torque blower — entry level. Elite is two-stage with either constant-torque (EL296E) or variable-speed (EL297V) at 96–97% AFUE — mid range. Signature (SLP99V) is fully modulating with a variable-speed blower at up to 99% AFUE — premium. Each step up improves comfort, reduces operating cost, and increases installed price.
Are these Canadian prices?
Yes. Every price reference in this article is in Canadian dollars (CAD) and reflects GTA installed costs as of August 2026. We do not use US pricing or equipment-only figures. Installed cost includes equipment, labour, Ontario TSSA permit, standard venting, and removal of your old furnace.
