Lennox Furnace Installation Toronto & GTA

Lennox furnace installation across Toronto and the GTA — including the industry-leading Signature SLP99V at up to 99% AFUE. Installed by a licensed gas technician and TSSA registered contractor.

Why Homeowners Choose Lennox

Lennox builds some of the most efficient, quietest furnaces on the market — a premium choice for long-term comfort.

Industry-Leading Efficiency

The Signature SLP99V reaches up to 99% AFUE — the highest residential rating available — turning almost every dollar of gas into heat through Ontario's long winters.

Quiet, Even Comfort

Variable-speed and modulating operation runs longer, gentler cycles that hold a steady temperature and run remarkably quietly — no blasts of hot air, no temperature swings.

Premium Build & Warranty

Lennox furnaces are engineered for reliability and backed by strong manufacturer warranties when registered. A sound long-term investment for homeowners staying put.

The Lennox Furnace Lineup

Signature Collection (SLP99V): the flagship modulating, variable-speed furnace at up to 99% AFUE — the quietest, most efficient, most precise comfort Lennox offers. Best for larger homes or homeowners who want the absolute best.

Elite Series (EL296): a 96% AFUE two-stage furnace that balances efficiency, comfort, and value — the sweet spot for most GTA detached homes. Merit Series (ML196): a dependable 96% AFUE single-stage unit at the most accessible Lennox price point. We size every job with a load calculation and match you to the right tier — see our furnace replacement page for the full process.

Lennox Furnace Questions

Lennox sits at the premium end of the market, and for homeowners staying in their home long-term it usually pays off. The Signature SLP99V reaches up to 99% AFUE — the highest residential efficiency available — and its variable-speed operation is exceptionally quiet and even. If you value the lowest possible gas bills and the quietest comfort over Ontario's long heating season, Lennox is hard to beat. We'll tell you honestly whether the premium makes sense for your home and how long you plan to stay.
The Lennox Signature Collection SLP99V is the flagship — a modulating, variable-speed gas furnace rated up to 99% AFUE, meaning almost all the gas you pay for becomes heat. Below it, the Elite EL296 (96% AFUE, two-stage) and Merit ML196 (96% AFUE, single-stage) offer strong efficiency at lower price points. We size and recommend the right tier for your home and budget.
Installed Lennox furnace pricing in the GTA generally runs from about $4,500 for a Merit-series unit to $10,500 for a top-tier Signature SLP99V, depending on size, staging, and any venting changes. The quote includes equipment, labour, the gas permit, and TSSA inspection. You get a fixed written price before we start.
Both are premium brands we install and trust. Lennox edges ahead on peak efficiency (the SLP99V's 99% AFUE is the highest available), while Carrier's Infinity series is renowned for its modulating comfort and reliability. Honestly, for most homes the install quality and correct sizing matter more than the badge. We carry both and recommend based on your priorities and budget.
