Furnace Installation in North York

$4,200 – $9,500 installed depending on efficiency tier, BTU, venting changes, and electrical scope. Most North York homes 1,500–2,500 sq ft land at $5,400 – $7,200 for a 96% AFUE 2-stage furnace. Free on-site Manual J assessment quotes the exact number.

TSSA G2 permit always (our gas-fitter partner pulls). ESA permit for the 120V tie-in. North York Building Permit if venting changes breach exterior wall. Simple like-for-like furnace swap (same fuel, same venting path) does NOT need a Building Permit, only TSSA + ESA.

In North York's climate the payback on the high-eff 96% AFUE is 6-9 years on fuel savings alone (gas $1.20-$1.50/m³ 2026 forecast). High-eff is also condensing (sealed combustion) — safer in tight homes and radon-zone basements. Mid-eff 80% is rarely the right choice for primary heating; we install it only for secondary suites, rental conversions, or where venting constraints prevent condensing.

Yes if the AC is < 8 years old and properly sized. Heat exchanger and blower coil compatibility is straightforward. Manual J checks airflow CFM and refrigerant compatibility (R-410A AC pairs with any new furnace; R-22 AC needs swap soon regardless). If AC is > 12 years old we discuss replacement bundling — installed together is $1,000-$2,000 cheaper than separately.

Indoor furnace swaps yes, with full permitting. Downtown North York postal codes (M5A, M5B, M5C, M5G, M5H, M5J, M5T, M5V) have limited Enbridge work windows May 1 – July 31 2026 during FIFA match windows. We can install on non-match days and complete commissioning the next business day. Plan for 2-3 day buffer in the downtown core during this window.

Manual J load calculation (ACCA standard). Rule-of-thumb (35-45 BTU/sq ft for typical North York detached) is acceptable for rough estimate; we always run a proper Manual J before ordering equipment. Oversized furnaces short-cycle, deliver lower comfort, and wear out faster. Right-size at install is free.

1 day for like-for-like swap (8-10 hours). 1.5-2 days if venting changes (condensing retrofit from mid-eff). 2-3 days if Enbridge gas-line upsize is required. Heat is off 4-6 hours mid-day during cutover; we coordinate to minimize disruption.

We haul away and recycle at MetalWorks North York (steel) / Enbridge meter-side recovery (gas valve). Refrigerant in any attached coil is recovered by ODP-certified tech (Ontario Reg 463/10). All in price.

10-year parts from the manufacturer (Lennox / Carrier / Trane / Bryant standard). 12-year heat exchanger from Trane / Carrier. 2-year RenoHouse labour warranty on the install. Lifetime warranty on the venting work.

Yes — three options. (1) Greener Homes Loan if part of deep retrofit (hybrid w/ heat pump). (2) North York HELP Loan if eligible (property tax repayment). (3) Standard financing through our partner Financeit at competitive rates — pre-approval in 24 hours, no early payoff penalty.

Yes, but most furnaces > 12 years old are not worth repair past $1,500. Common repairs: igniter ($280-$420), inducer motor ($580-$850), pressure switch ($320-$480), flame sensor cleaning ($180). Above $1,500 we recommend replacement quote. Diagnostic fee $180 (waived if we do the work).
