What moves the price in Ottawa
- Stage: two-stage adds roughly $1,000 to $2,500 over single-stage in these lists; modulating more again.
- Venting: converting a chimney-vented furnace to PVC venting adds $200 to $500 (Gas Man Ottawa).
- Ductwork: $1,000 to $3,000 when the ducts need real work, not just a transition (Colair).
- Furnace and AC together: $8,000 to $15,000 (Oria Heating & Cooling).
- Permits and removal: included in Colair’s prices; check every quote.
Permits and who can do the work
We did not find a published Ottawa fee for a stand-alone furnace permit to quote here. The contractor price pages we checked either include the permit or list $100 to $400 for it. Ask whether a permit is being pulled and whether it is in the price.
Only a TSSA-registered contractor with a certified gas technician should disconnect and connect a gas furnace. Ask for the registration number on the quote.
Rebates in 2026: what is real
There is no Ontario rebate for a new gas furnace in 2026. The Home Renovation Savings Program pays for heat pumps, not furnaces, and Enbridge’s Home Efficiency Rebate ended intake on January 27, 2025. Be wary of any quote that promises a furnace rebate.
- Home heated with natural gas: a cold-climate air-source heat pump earns $500 per ton, up to $2,000; ground-source $3,000.
- Home heated with electricity, oil, propane or wood: $1,250 per ton, up to $7,500; ground-source $2,000 per ton, up to $12,000.
- Federal: on October 8, 2026 Ottawa announced a heat pump rebate of up to $10,000 for households below the median income and $2,000 for other eligible homeowners, for cold-climate air-source heat pumps.
If you are replacing a furnace anyway, price a heat pump or a dual-fuel setup at the same time: heat pump cost in Ontario and heat pump rebates.
How to get a fair Ottawa quote
- Get two or three quotes on the same written scope: furnace model and efficiency, stage (single, two-stage or modulating), venting, duct changes, permit, removal and warranty.
- Ask for HST shown as a separate line.
- Ask whether the price includes a load calculation or just matches the old furnace size. See HVAC sizing mistakes.
