How Much Does Furnace Installation Cost in Toronto in 2026?

What Drives the Price Up or Down
- Efficiency rating (AFUE) — high-efficiency condensing furnaces (96%+ AFUE) cost more upfront but cut gas bills for 15–20 years.
- Size (BTUs) — the unit must be matched to your home’s heat load; oversized or undersized both waste money.
- Brand and model — we install Lennox, Bosch, Amana, and Midea across a range of price points.
- Installation complexity — venting changes, gas line work, or ductwork modifications add to the job.
- Existing setup — a straight swap costs less than converting from another heating type.

Repair or Replace? The 50% Rule
HVAC pros use a simple guideline: if your furnace is over 15 years old and a repair would cost more than 50% of a new unit, replacement is usually the better investment — you’ll gain efficiency, reliability, and warranty coverage. If the unit is younger and the fix is minor, repair almost always wins.

How to Get the Best Value
- Get the size right — a proper heat-load calculation beats rule-of-thumb sizing every time.
- Compare total cost, not just the sticker — a 96%+ AFUE unit can save hundreds per year on gas.
- Ask what’s included — permits, venting, thermostat, and old-unit removal should be itemized.
- Check the warranty — ours covers workmanship on top of the manufacturer’s warranty.
