One, for almost every house. Raise it only if the property genuinely runs more than one furnace, such as a duplex or a home with a separate system serving an addition.

Installed price, equipment and labour together. Efficiency is the variable the source says moves the price most.

Where these numbers come from

The base is the single-stage 80% AFUE installed range Custom Contracting publishes for Ontario, $3,500 to $5,000. The other two options are that page's own installed ranges for those furnace types, carried across as a multiple of the base. The page states its prices include equipment, labour, permits and removal of the old furnace, which is why this calculator adds no separate permit line.

How it compares against Ottawa figures

  • A second Ontario guide, compiling four independent 2026 contractor and industry sources, publishes an overall installed range of $3,500 to $10,000 or more, a provincial average around $6,800 before tax, and a narrower typical band of $4,000 to $6,500 for straightforward replacements. Its tiers are $3,500 to $5,500 single-stage, $5,000 to $7,500 two-stage and $7,000 to $10,000 or more modulating, within a few hundred dollars of the figures used here at every tier.

Checked against the source’s own examples

The cost source publishes total project costs for these builds. Entering them above reproduces its figures, which is how the encoding here is verified rather than asserted.

BuildPublished total
One single-stage 80% AFUE furnace$3,500 to $5,000
One two-stage 92 to 95% AFUE furnace$4,500 to $7,000
One modulating 96 to 98% AFUE furnace$6,000 to $10,000

What this does not know

  • This prints a range, not a quote. It also prints Ontario figures rather than Ottawa ones, because no Ottawa source with tier-by-tier installed pricing could be verified on 2026-08-28. Read it as the provincial picture.
  • There is no home-size control. Both sources publish cost by home size as well as by furnace type, and multiplying the two together would count efficiency twice. The second guide puts it plainly: a larger home mostly pushes you into the next efficiency tier rather than adding a linear amount inside the one you are in. Pick the tier, not the square footage.
  • The installed price covers equipment, labour, permits and removal of the old furnace, on the source's own statement. What it prices separately is not included here: ductwork modifications $500 to $3,000, flue or venting upgrades $300 to $1,200, gas line work $200 to $800, a smart thermostat $150 to $500, a CO detector $50 to $150, humidifier installation $400 to $900, and disposal of the old equipment $75 to $200.
  • Brand is left out on purpose. The same page prices premium brands at $400 to $1,500 above value brands, and that is a flat dollar premium rather than a percentage, so turning it into a multiplier would misstate it at the other two tiers, and it is left off the form instead.
  • Rebates are not deducted. The source names the Enbridge Home Efficiency Rebate Plus at up to $6,500 and the Canada Greener Homes Grant at up to $5,000, and says most programs need a pre-retrofit home energy assessment before work begins. The second guide, read the same day, states the federal Canada Greener Homes Grant closed to new applicants in January 2026. Check what is open before you count on either.
  • Timing carries a premium neither this form nor the base source applies: the second guide publishes 20 to 50 per cent more for an emergency mid-winter replacement than for the same job booked in spring or fall. It comes from a different page than the figures being multiplied, so it stays out of the arithmetic and in this list.
  • No business pays for a listing or for position on this directory, including the companies shown below this calculator.

Questions people ask

How much does a new furnace cost in Ontario in 2026?
Custom Contracting publishes $3,500 to $5,000 installed for a single-stage 80% AFUE furnace, $4,500 to $7,000 for a two-stage 92 to 95% model and $6,000 to $10,000 for a modulating 96 to 98% one, all including equipment, labour, permits and removal of the old unit. The Heating Guide, compiling four Ontario sources, lands within a few hundred dollars at every tier and puts the provincial average near $6,800 before tax. Both are Ontario-wide rather than Ottawa-specific.
Is a high-efficiency furnace worth the extra cost?
The source's own answer is yes in most cases. It puts a 96% AFUE furnace at $1,500 to $3,000 more upfront than an 80% model, saving $300 to $600 a year on gas in Ontario's climate, with payback typically four to seven years. The same page states $400 to $600 a year in a second place, so read the saving as a band rather than a figure. Rebates, where they are open, can cover most of the premium.
Does the price include the permit?
On this source's figures, yes. It states that all prices include equipment, labour, permits and removal of your old furnace, which is why this calculator adds no permit line. That is not universal: The Heating Guide lists municipal permits in Ontario at $200 to $500 as a separate item. Ask each bidder in writing whether the permit is inside their number.
Should I replace the furnace and the air conditioner at the same time?
The source says replacing both together saves 15 to 25 per cent on labour against doing them separately, and puts a combined furnace and air conditioner replacement in Ontario at $8,000 to $18,000 depending on efficiency and brand. That combined figure is not a multiple of the furnace tiers above, so this calculator does not offer it as an option.
Is this an estimate or a quote?
An estimate, and an Ontario one. It multiplies a published installed range by the number of furnaces you are replacing. Get the real number from a licensed contractor who has run a load calculation on your house rather than matched the BTU number on your old unit, and start with the companies listed below.
