Free furnace quote tools and HVAC cost calculators
Estimate a price before anyone visits, check a quote once you have one, and line up two or three side by side. All three tools use the same typical Ontario ranges, run in your browser and send nothing to us.
Three tools, one set of numbers
Each tool answers one question, from the same typical Ontario ranges as the FurnaceQuotes.ca home page. Pick the one that matches where you are in the process.
Which tool to use, and when
Most homeowners use all three in this order: a budget first, then a check on each quote, then a side-by-side comparison.
Before the estimate: furnace price estimator
Answer three questions about home size, fuel and efficiency to get a typical installed range for your home, before HST. Use it to set a budget and to spot a number that is far off before anyone visits. Estimate a furnace price
After you get a quote: quote checker
Type in the system, efficiency, home size, price and the extras listed on the quote. You get a verdict (fair, a bit high, well above typical or low), the range it used and the reasons. Check a quote
With two or three quotes: comparison worksheet
Put each quote on the same rows: price, model number, efficiency, warranty years, venting, permits and removal. Gaps show up fast, and the sheet prints cleanly for the kitchen table. Compare quotes side by side

Typical Ontario prices in CAD, before 13% HST. Reviewed October 2026. Ranges, not quotes.
We built these ranges from Ontario contractors' published prices, manufacturer and distributor list-price guidance and the scope of a typical install, and checked them in October 2026. Your own quote will still depend on the house, access, venting, ductwork, brand choice and time of year. Read our methodology
Private by design
The tools run in your browser. Nothing you type is sent to us or to any company, and there are no cookies or tracking scripts. The comparison worksheet saves on this device only, and one button clears it.
Common questions
Straight answers. If yours is not here, the company can answer it during your free estimate.
How accurate are these furnace cost calculators?
As accurate as a typical range can be. Each tool uses Ontario installed prices for a standard replacement, reviewed October 2026, and adjusts for the details you enter. None of them can see your venting, ducts or access, so treat the result as a sanity check. A written quote after an in-home estimate is the only real price.
Do the tools save or send what I type?
Nothing you type leaves your browser. The estimator and the quote checker work it out on your device and send nothing anywhere. The comparison worksheet keeps your entries on this device only, so you can come back to them, and one button clears them. The site uses no analytics, tracking pixels or cookies.
Are the prices before or after HST?
Before 13% HST unless a tool says otherwise. The quote checker has a box to tick if your price already includes HST, and it takes the tax out before comparing. To add HST to any range yourself, multiply by 1.13: $8,000 before tax is $9,040 with HST.
Skip the math, get a real number
Answer a few quick questions. A participating local HVAC company confirms the details, visits for a free in-home estimate and gives you a written quote to check.
