How much does a new furnace installation cost in Toronto?

A new furnace installation in Toronto typically costs between $3,000 and $7,500 depending on the brand, model, efficiency rating, and any ductwork modifications required. A standard-efficiency (80% AFUE) furnace is on the lower end, while a high-efficiency modulating unit (96%+ AFUE) with a variable-speed blower is at the higher end. After rebates, your out-of-pocket cost can be significantly lower. See our furnace cost guide for a detailed breakdown.

How long does furnace installation take?

A standard furnace replacement is typically completed in one day, usually 4 to 8 hours. If your installation requires ductwork modifications, new venting, or electrical upgrades, it may extend to a second day. We confirm the expected timeline during your in-home assessment before any work begins.

What are the best furnace brands for Toronto homes?

The best brand depends on your budget and priorities. Carrier and Lennox are premium brands known for reliability and quiet operation. Goodman offers excellent value with strong warranties. Daikin and Trane are well-regarded for durability. Kepler is a newer brand gaining popularity for high-efficiency models at competitive prices. Our technicians will recommend the best fit based on your specific needs.

How do I know what size furnace I need?

Furnace sizing is based on a Manual J heat load calculation that considers your home's square footage, insulation levels, window quality, ceiling height, and local climate data. An oversized furnace short-cycles and wastes energy, while an undersized one cannot keep up in extreme cold. We never guess on sizing. Every installation includes a proper calculation to ensure optimal performance.

What rebates are available for a new furnace in Ontario?

Standard gas furnaces are not covered by current rebate programs — Ontario's Home Renovation Savings Program targets cold-climate heat pumps and heat-pump water heaters, not furnaces. If you are also considering a heat pump, a qualifying cold-climate unit may be eligible for up to $7,500, depending on your current heating fuel. Visit our rebates page for details, and confirm eligibility directly with the program.

Do you offer financing for furnace installation?

Yes. We offer multiple financing options including traditional financing with low monthly payments and our lease-to-own program with $0 down. The lease-to-own option includes installation, equipment, and ongoing maintenance coverage in one fixed monthly payment. We work with you to find a payment plan that fits your budget.

When to Replace Your Furnace

A furnace typically lasts 15 to 20 years with proper maintenance. However, age alone is not the only factor. Here are the most common signs that it is time to invest in a new furnace rather than continuing to repair your existing one:

Your furnace is 15 years old or older and efficiency has noticeably declined

A cracked heat exchanger has been diagnosed, which poses a carbon monoxide risk

Your system still uses R-22 refrigerant (phased out in Canada) or outdated components

Heating bills keep rising despite regular maintenance and repairs

You have needed two or more major repairs in the past two years

Rooms heat unevenly or the furnace struggles to maintain the set temperature

The furnace makes loud banging, rattling, or grinding noises during operation

Visible rust, corrosion, or cracks on the furnace body or flue pipes

Types of Furnaces We Install

Choosing the right furnace type depends on your home size, budget, and comfort preferences. We install all three major categories.

Single-Stage Furnace

Operates at one fixed output level, either fully on or off. These are the most affordable option upfront and work well for smaller homes or those on a tight budget. Typical AFUE ratings range from 80% to 92%.

Two-Stage Furnace

Runs at a lower output most of the time and ramps up to full capacity only when needed. This results in more consistent temperatures, quieter operation, and lower gas bills compared to single-stage models. AFUE ratings typically range from 92% to 96%.

Modulating Furnace

Continuously adjusts its flame and blower speed in small increments to maintain the exact temperature you set. This is the most efficient and comfortable option available, with AFUE ratings of 96% to 98%. Ideal for larger homes or homeowners who want the lowest possible energy bills.

Our Furnace Installation Process

In-Home Assessment and Sizing

A licensed technician visits your home to evaluate your existing system, ductwork, insulation, and square footage. Proper sizing is critical: an oversized furnace short-cycles and wastes energy, while an undersized unit cannot keep up on the coldest days. We perform a Manual J heat load calculation to determine the exact capacity your home needs.

Written Quote and Equipment Selection

You receive a detailed written quote that includes the furnace unit, all materials, labour, permits, and applicable rebates. We walk you through the options so you can make an informed decision. No pressure, no hidden fees.

Old Furnace Removal

On installation day, our team safely disconnects and removes your old furnace and any outdated components. We handle all disposal and recycling in accordance with Ontario regulations.

New Furnace Installation

Your new furnace is installed with proper gas line connections, electrical wiring, venting, and ductwork modifications as needed. We follow all TSSA codes and obtain the required permits for gas work in Ontario.

Testing and Commissioning

We run the furnace through multiple heating cycles, verify gas pressure, check for leaks, test the thermostat, and ensure every component operates within manufacturer specifications. You receive a full walkthrough of your new system before we leave.

Furnace Efficiency Ratings Explained

Furnace efficiency is measured by its Annual Fuel Utilization Efficiency (AFUE) rating, which tells you what percentage of gas is converted into usable heat. A higher AFUE means lower gas bills.

Standard Efficiency (80% AFUE)

20 cents of every dollar in gas is wasted
Lower upfront cost but higher monthly bills
Uses a chimney flue for exhaust venting
Does not qualify for most government rebates

High Efficiency (96%+ AFUE)

Only 4 cents or less of every dollar is wasted
Saves $300-$600+ per year on gas bills
Direct-vent (PVC pipe) exhaust, no chimney needed
Qualifies for government and manufacturer rebates

We recommend 96% AFUE or higher for most Toronto homeowners. The energy savings typically pay for the difference in upfront cost within 3 to 5 years, and you may qualify for significant rebates that further reduce the investment.
