Furnace replacement cost calculator
Replacing a furnace is one of the bigger jobs in the home, and the price swings a lot depending on the fuel type, the efficiency rating, the size of your house and how much ductwork has to change. Set the options below for a realistic Canadian ballpark, supplied and installed, before you call around for quotes.
Price up a furnace replacement
Gas furnaces are the most common; electric runs cheaper to install, oil costs more.
Higher AFUE means lower running costs but a higher up-front price.
A larger home needs a higher-capacity furnace and more labour.
Reusing existing ducts is cheapest; new or modified ductwork adds materials and labour.
A Canadian supply-and-install ballpark, not a fixed quote. Most furnace replacements land around 3,000 to 6,500 dollars installed depending on size, efficiency and fuel. Get an in-home estimate from a licensed HVAC contractor for an exact price.

What goes into the price
A furnace replacement quote is really two things added together: the furnace itself and the labor to install it. A straight like-for-like swap with existing ductwork is the cheapest and quickest job. The price climbs when you move to a high-efficiency model, when the home is larger and needs more heating capacity, or when the installer has to add or modify ductwork.
Choose your fuel type and efficiency rating, set your home size, and say whether you are reusing existing ducts or adding new ductwork.
See a low-to-high cost estimate and a typical mid-point, so you know the ballpark to budget for and what a fair quote looks like.
Use your range to brief two or three licensed HVAC contractors and ask each to do an in-home estimate and quote in writing.

Estimate = base furnace and install + fuel type + efficiency + home size + ductwork Why two quotes for the same furnace look so different
The job is rarely the same twice
Two homes with the same furnace can be a thousand dollars apart. An easy basement swap is cheap labor, an awkward attic install with modified ductwork is not. The fuel type, the efficiency rating you choose, your home size, and how much ductwork has to change all move the number, which is why a range is more honest than a single figure.
The job goes to the contractor who answers
Most homeowners call three or four contractors and book the first good one who actually picks up. The ones who miss the call lose the job to whoever answered. Hey Jodie answers every call 24/7 for HVAC and plumbing firms, takes the details and books the visit - so quotes do not slip away while the technician is in a crawlspace. It books jobs and captures inquiries; it does not give out prices.
Frequently asked questions
How much does a furnace replacement cost in Canada? +
For most homes a furnace supplied and installed lands somewhere around 3,000 to 6,500 dollars. A straight like-for-like gas swap with existing ductwork is at the lower end, while a high-efficiency model, a larger home, an oil furnace or new ductwork pushes it higher. Set the options above for a ballpark closer to your own home.
What affects the price of a furnace replacement? +
The main drivers are the fuel type (gas, electric or oil), the efficiency rating you choose, the size and heating capacity you need for your home, and how much ductwork has to change. A like-for-like swap using existing ducts is cheapest; a high-efficiency model, a larger home, or new and modified ductwork all add to both parts and labour.
Is a high-efficiency furnace worth the extra cost? +
A high-efficiency furnace (95 percent AFUE or higher) costs more up front than a standard 80 percent model, usually several hundred to a couple thousand dollars more installed, but burns less fuel and can lower your heating bills over time. In a cold Canadian climate the savings add up faster. A good contractor can walk you through the difference for your home.
Is this furnace cost estimate accurate? +
It is a realistic Canadian ballpark based on typical 2026 supply-and-install prices, meant for budgeting and for sense-checking the quotes you get. It is not a fixed quote. Your real price depends on your exact furnace, your home and the condition of your existing system and ductwork, so treat the range as a guide and get an in-home estimate before you commit.
How do I get an exact quote for a furnace replacement? +
Use the range here to set your budget, then ask two or three licensed HVAC contractors to do an in-home estimate and quote in writing. A proper quote should list the furnace make and model, the AFUE rating, the warranty, the labour, and any extras like ductwork, a new thermostat or permits. Compare like for like rather than just picking the lowest headline number.
Does the estimate include removing the old furnace? +
Yes - the base figure assumes a standard installation that includes taking out and disposing of your old furnace and installing the new one in the same place using existing ductwork. Extras that are not always included, such as new or modified ductwork, an oil-to-gas conversion or major venting changes, sit on top, which is why the higher end of the range exists.
