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.
Lennox builds some of the most efficient, quietest furnaces on the market — a premium choice for long-term comfort.
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.
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.
Lennox furnaces are engineered for reliability and backed by strong manufacturer warranties when registered. A sound long-term investment for homeowners staying put.
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.
