Furnace replacement cost in Ontario after rebates (2026)

Last verified October 19, 2026 against official program pages. How we check

As of October 19, 2026, no program open today pays for a new gas furnace in Ontario. A new furnace typically costs $5,000 to $7,000 installed.

Replacing it with a cold-climate heat pump instead costs $10,000 to $19,000, and about $1,500 comes back if your home is heated by natural gas, so you’d pay about $8,500 to $17,500.

Every program here is listed on Ontario home energy rebates. The biggest typical amount comes from Home Renovation Savings Program. How programs combine is in our stacking guide.

Questions people ask

Standard gas furnace, installed: $5,000 to $7,000, from Green Venture, checked October 17, 2026. Your installer’s quote decides the real price.

Not in our data as of October 19, 2026. Programs in Ontario now pay to replace a furnace with a heat pump instead.

Often, but check the order of steps first. Some programs need approval or an energy assessment before work starts, and a rebate can be lost by installing first. The National Heat Pump Rebate is meant for homes replacing a failed or end-of-life system, but it isn’t open yet.

Yes. In Ontario, about $1,500 comes back if your home is heated by natural gas, through Home Renovation Savings Program.

It is announced but not open as of October 19, 2026, so we don’t count it. If it opens before you install, it adds $2,000. Programs open today don’t need to wait.

Home size, existing ducts, the electrical panel, the brand and whether the installer removes old equipment all change the price. Compare at least two written quotes for the same scope.
