Three Questions That Actually Matter
A furnace installation is a bigger decision than a repair, you’re picking equipment that will run your home for the next 15 to 20 years, so getting the sizing, the fuel type, and the quote itself right the first time saves real money over that whole lifespan.
In our experience, the single most common mistake homeowners make is comparing quotes on price alone without checking whether each quote includes the same scope of work, see the checklist further down before you sign anything. A properly matched installation also means increased energy efficiency, safer operation, better indoor air quality, and more even heating throughout the home.
Repair or Replace
When Does a Furnace Need Replacing, Not Repairing?
A furnace earns a replacement recommendation when several of these line up at once, not just one.
Age Past 15–20 Years
Most gas furnaces are designed for that lifespan, and repair parts get harder to source as a unit ages out of production.
Repeated Repairs, One Season
More than one repair call in the last 12 months means the unit is telling you something a single fix won’t solve.
Rising Bills, Same Usage
A sign the unit is losing efficiency faster than a repair can recover.
Never Sized Correctly
Common in older Burlington and Hamilton housing with finished basements or additions. Repair after repair on a mis-sized unit just delays the same conversation.
Repair Quote > Half of New Install
At that point the math almost always favours replacement.
No Surprises
How Much Does Furnace Installation Cost in Ontario?
Installed pricing runs $3,500 to $9,000, with most homeowners landing between $4,500 and $7,000. Fuel type is the biggest driver.
| Furnace Type | Estimated Cost |
|---|---|
| Electric Furnace | $2,500 – $6,000 |
| Standard-Efficiency Gas Furnace | $3,500 – $6,500 |
| High-Efficiency Gas Furnace (95%+ AFUE) | $5,500 – $9,000 |
| Oil Furnace | $6,000 – $10,000 |
A high-efficiency furnace costs more upfront but typically pays some of that back through lower monthly gas bills. Ductwork modifications, an electrical panel upgrade, or converting from oil to gas each add cost on top of the numbers above, your quote should call these out separately.
