Everything you need to know about furnace prices, installation costs, brand comparisons, and available rebates in the Greater Toronto Area.
A new furnace in Toronto costs between $3,000 and $7,500 installed in 2026, depending on efficiency, brand, and home size. With available Ontario rebates, your out-of-pocket cost could be as low as $1,500–$3,000.
Mid-Efficiency
$3,000–$5,000
80% AFUE, installed
High-Efficiency
$4,500–$7,500
96%+ AFUE, installed
Modulating
$5,500–$8,500
Variable speed, installed
Furnace prices vary significantly based on efficiency rating. Higher-efficiency models cost more upfront but save hundreds per year on natural gas bills. All prices below include professional installation in the Toronto area.
| Furnace Type | Efficiency (AFUE) | Installed Cost | Best For |
|---|---|---|---|
| Mid-Efficiency | 80% AFUE | $3,000–$5,000 | Budget-conscious, rental properties |
| High-Efficiency | 96%+ AFUE | $4,500–$7,500 | Most homeowners, rebate eligible |
| Modulating / Variable Speed | 97%–98% AFUE | $5,500–$8,500 | Maximum comfort, quietest operation |
Note: Mid-efficiency (80% AFUE) furnaces are being phased out across Canada. Most new installations in Ontario use high-efficiency models, which also qualify for government rebates.

No two furnace installations are identical. Several factors determine your final price beyond the cost of the unit itself. Understanding these variables helps you budget accurately.
Larger homes need higher-BTU furnaces. A 1,200 sq ft bungalow may only need a 60,000 BTU unit, while a 3,000 sq ft two-storey home could require 100,000+ BTUs. Bigger units cost more.
If your existing ductwork is undersized, damaged, or poorly sealed, modifications may be needed. Duct repairs or upgrades can add $500–$2,000 to the installation cost.
Higher AFUE means more of every dollar of gas is converted to heat. A 96% AFUE furnace costs more upfront than an 80% model, but saves $300–$600 annually on heating bills.
Premium brands like Lennox and Carrier cost more but offer better warranties and quieter operation. Features like variable-speed blowers and modulating gas valves add to the price.
Switching from mid-efficiency to high-efficiency requires new PVC venting. Difficult access, gas line upgrades, or electrical work can increase labour costs by $300–$1,000.
The City of Toronto requires permits for furnace installations. Permit fees typically run $150–$300. A reputable installer handles the permit process for you.
Not every furnace issue requires a full replacement. Here is how to determine whether a furnace repair makes more sense than investing in a new unit.
Not sure which option is right for you? Our technicians provide honest assessments. We will never recommend a replacement when a repair will do. Book a diagnostic appointment and we will give you a straightforward recommendation.
Ontario homeowners can significantly reduce the cost of a new furnace through federal and provincial rebate programs. Here are the programs available in 2026.
Up to $5,000
The federal Home Efficiency Rebate Plus (HER+) program offers rebates for energy-efficient home upgrades, including high-efficiency furnace installations. Requires a pre- and post-retrofit EnerGuide home energy audit. High-efficiency furnaces (96%+ AFUE) qualify.
Up to $5,000+
Provincial programs and utility-sponsored incentives provide additional rebates for energy-efficient heating upgrades. Enbridge Gas and local utility companies often offer seasonal rebates that can be stacked with federal programs. Check our rebates page for current availability.
$200 – $1,000+
Carrier, Lennox, Trane, and other manufacturers run seasonal promotions offering instant rebates or extended warranties on qualifying models. These can be combined with government rebates for maximum savings.
6 Months Free + Up to $750 Cashback

Learn MoreProper sizing is critical. An undersized furnace will struggle to heat your home on the coldest Toronto winter days, while an oversized unit will short-cycle, wasting energy and wearing out components faster. Here are general guidelines based on home size.
| Home Size (sq ft) | Recommended BTUs | Typical Cost (Installed) |
|---|---|---|
| 800 – 1,200 sq ft | 40,000 – 60,000 BTU | $3,000 – $5,000 |
| 1,200 – 1,800 sq ft | 60,000 – 80,000 BTU | $3,500 – $6,000 |
| 1,800 – 2,500 sq ft | 80,000 – 100,000 BTU | $4,500 – $7,000 |
| 2,500 – 3,500+ sq ft | 100,000 – 120,000+ BTU | $5,500 – $8,500 |
