When To Replace Your Furnace in Toronto

Most gas furnaces in Toronto homes last 15 to 20 years. If yours is past 15, replacement usually costs less over five years than a string of repairs on a unit that’s running at 70% efficiency. Watch for these signs:

• Age 15+ years. Heat exchangers fatigue. Cracked exchangers leak carbon monoxide and force immediate red-tag shutdown by Enbridge.
• Rising gas bills with no usage change. An old 80% AFUE furnace burns roughly 20% more gas than a modern 96% unit to make the same heat. On a Toronto winter bill, that adds up fast.
• Uneven heat between floors. Single-stage burners and tired blowers can’t balance a two or three-storey home the way a variable-speed unit does.
• Yellow or flickering pilot flame. A healthy flame burns blue. Yellow means incomplete combustion and possible CO production.
• Frequent repair calls. If you’ve spent more than $1,500 on repairs in the last two seasons, you’re funding a furnace that owes you nothing.
• Loud bangs, rattles, or short cycling. Symptoms of a failing inducer motor, control board, or oversized unit cycling itself to death.

Not sure if you’re at the replacement point? Book a diagnostic and we’ll give you the honest read. Sometimes a furnace repair buys you another season or two.

Furnace Types We Install

Ontario building code requires new gas furnace installations to hit a minimum AFUE of 96%, so every furnace we install is high-efficiency by default. AFUE (Annual Fuel Utilization Efficiency) measures how much gas turns into usable heat: a 96% AFUE furnace converts 96 cents of every gas dollar into heat, with 4 cents lost up the flue.

• Single-stage 96% AFUE. Burner runs full blast or off. Strong choice for smaller Toronto bungalows and condos under 1,500 sq ft. Lowest equipment cost.
• Two-stage 96-97% AFUE. Runs at low fire about 80% of the time, kicks to high fire on the coldest nights. Quieter, more even temperatures, better humidity control. Our most popular pick for typical Toronto two-storey homes.
• Modulating + variable-speed 97-98.5% AFUE. Adjusts burner output in 1% increments and pairs with an ECM blower that ramps in fine steps. Highest comfort, lowest sound, biggest gas savings. Best fit for larger or open-concept Toronto homes, custom builds, and anyone planning to add a heat pump later.

How Much Does Furnace Installation Cost in Toronto?

Most Toronto furnace installations land between $4,500 and $9,000 installed, before rebates. That spread covers a lot of ground, so here’s what actually moves the price:

• BTU size. Toronto homes typically need 60,000 to 100,000 BTU. Larger homes or poorly insulated older properties in areas like the Annex or High Park can push higher.
• Efficiency tier. A single-stage 96% Goodman or KeepRite sits at the lower end. A modulating Lennox SLP99V variable-speed sits at the top.
• Brand. Lennox premium lines run higher than Goodman or Tempstar for similar BTU and AFUE ratings.
• Venting work. A high-efficiency furnace vents through PVC, not the old metal chimney. If we’re converting from mid-efficiency, expect added labour for new vent routing.
• Gas line and electrical. Older Toronto homes sometimes need a gas line upsize or a dedicated 120V circuit. Toronto Hydro permits the electrical tie-in.
• Permits. The City of Toronto requires a gas permit for any furnace install. We pull it for you and the cost is built into the quote.
• Add-ons. Smart thermostat, humidifier, HEPA filter, UV light, or a matching AC tie-in.

We provide same-day written quotes with all-in pricing. No surprise charges for venting, permits, or disposal of the old unit. Ask about our $0 down financing if you’d rather spread the cost.

Our Toronto Furnace Installation Process

1. Free in-home consultation. A licensed gas tech inspects your existing system, ductwork, gas line, and electrical.
2. Manual J load calculation. We size the furnace to your actual home, not a rule-of-thumb. Oversized furnaces short-cycle and waste gas.
3. Same-day written quote. All-in price with brand options and rebate estimates.
4. Permit and scheduling. We pull the City of Toronto gas permit and book your install, often within 48 hours.
5. Removal and install. Most installs take 4 to 8 hours. We protect floors, haul the old unit, and set the new furnace.
6. Commissioning. Combustion analysis, gas pressure check, safety verification, thermostat pairing, and a walk-through.
7. Warranty registration. We register your equipment so your manufacturer warranty starts the day of install.

Ontario Rebates and Financing

Several programs stack to bring your out-of-pocket Toronto furnace install down significantly. We file the paperwork on your behalf.

• Enbridge Gas Home Efficiency Rebate Plus (HER+). Up to several thousand dollars when you bundle a high-efficiency furnace with insulation, windows, or other envelope upgrades, with a pre and post energy audit. Often the largest rebate available to Toronto homeowners.
• Canada Greener Homes Grant / Loan. Interest-free loans up to $40,000 for eligible energy retrofits, including high-efficiency furnaces paired with envelope work. Application runs through the federal portal after the EnerGuide audit.
• Home Efficiency Rebate Plus (income-qualified stream). Increased rebate amounts for qualifying households. We confirm eligibility during the consult.
• Manufacturer rebates. Lennox, KeepRite, and Tempstar run seasonal cash-back promotions. We apply current offers to your quote automatically.
• 0% financing. Approved Toronto homeowners can spread the install over 12 to 60 months with no interest, subject to credit approval through our finance partners.

Frequently Asked Questions

How much does a new furnace cost in Toronto?

Installed prices typically run $4,500 to $9,000 before rebates, depending on BTU size, efficiency tier, brand, and venting requirements. A single-stage 96% AFUE unit for a smaller Toronto home sits at the lower end. A modulating variable-speed unit for a larger home sits at the top. We provide free written quotes with all-in pricing.

How long does a furnace installation take?

Most Toronto furnace installs take 4 to 8 hours from arrival to commissioning. Conversions from mid-efficiency to high-efficiency can run longer because we add new PVC venting and may reroute the gas line. We aim to finish same-day so you’re not without heat overnight.

What AFUE rating do I need in Ontario?

Ontario building code requires new gas furnace installations to meet a minimum 96% AFUE. AFUE measures the percentage of gas converted to usable heat. A 96% AFUE furnace burns about 20% less gas than an old 80% AFUE unit, which is the main reason replacing an aging furnace pays back fast on Toronto winter bills.

How do I know what BTU size furnace my Toronto home needs?

We run a Manual J load calculation that factors in square footage, insulation, window type, ceiling height, and air leakage. Most Toronto homes land between 60,000 and 100,000 BTU. Skip the square-foot rule of thumb: oversized furnaces short-cycle, run noisy, and waste gas. We size the unit to your actual home.

What rebates are available for a new furnace in Toronto?

The big three are the Enbridge Gas Home Efficiency Rebate Plus (HER+), the Canada Greener Homes Loan (interest-free up to $40,000), and seasonal manufacturer rebates from Lennox, KeepRite, Tempstar, and others. Bundling a furnace with insulation or window upgrades unlocks the largest combined incentives. We file the rebate paperwork for you.

Do you offer financing on furnace installations?

Yes. Approved Toronto homeowners can finance at 0% over 12 to 60 months with no down payment, subject to credit approval through our finance partners. Many customers pair financing with rebates so the monthly cost lands close to their existing gas savings.

What warranty comes with a new furnace?

Standard manufacturer coverage on the furnaces we install is 10 years on parts and a lifetime warranty on the heat exchanger for most premium models. We register your equipment at install so coverage starts on day one. Labour warranty terms vary by package and we spell them out clearly on the quote.
