How to read a price range

Every range here, as in the index on the Ontario Furnace Prices home page, describes the same job: a standard replacement in an existing detached home, with reusable ductwork and venting, before 13% HST. It is the band fair quotes for that job usually fall into, not a promise for yours.

Low end$4,000

A like-for-like swap: easy access, venting and ducts reused, an entry model, a quiet month.

Midpoint$5,250

A sensible budget figure before anyone has seen your house.

High end$6,500

Harder access, more labour, a better model within the tier, or a busy January week.

Extras such as new venting, ductwork changes or a gas line are priced on top of the range, not inside it.

Use the low end to spot a quote that leaves something out, the midpoint to set a budget and the high end to test a quote above it. A quote outside the range is not automatically wrong; ask what is different about your job.

What pushes a quote to the top of the range

The equipment sets the base price. The house sets most of the rest:

• Venting. A new vent run or a chimney liner adds $300 to $1,500.
• Ductwork. Transitions, a bigger return or reworked runs add $500 to $3,000+.
• Electrical. Heat pumps often need a new circuit ($500 to $2,500), sometimes a panel upgrade ($2,000 to $4,500).
• Access. Attics, crawlspaces and finished basements add labour hours.
• Tier. Staged burners, variable-speed equipment and premium lines sit at the top of each band.
• Timing. A January breakdown leaves little room to compare quotes.

Our price methodology explains where the ranges come from.

Questions people ask

Are these prices quotes?

No. They are typical 2026 installed ranges, compiled from publicly posted Ontario contractor pricing, list-price guidance and typical installation scopes. Only a written quote after an installer has seen your home is a firm number. See how we estimate prices.

Do the prices include HST?

No. Every range is before 13% HST, which applies to the whole job, equipment and labour. Multiply by 1.13 to compare with a quote that includes tax: a $6,000 job is $6,780 with HST.

Why is the heat pump range so much wider than the furnace range?

A heat pump's price depends on its capacity, its cold-climate rating, whether your panel and ducts can handle it, and whether a furnace stays as backup. A whole-home ducted system runs $9,000 to $18,000. See heat pump prices for the breakdown.

Which heating system is cheapest to install in Ontario?

A single-zone mini-split ($3,500 to $6,500) and a single-stage gas furnace ($4,000 to $6,500) have the lowest entry prices. Cheapest to install is not cheapest to run, so compare yearly costs with the heating cost calculator.
