Quick Answer
In Toronto, furnace repair makes sense when the unit is under 12 years old and the repair costs less than about 30% of replacement. If it’s 15 years or older or breaking down repeatedly, replacement is usually smarter. New installations in Jefferson County average $2,635–$5,610, offering quieter operation and stronger energy savings.
Why It Matters in Toronto
Toronto’s riverfront location brings damp, icy air each winter, which pushes older gas furnaces to their limits. Many homes along Franklin Street, River Avenue, and the downtown hillsides were built before 1980 with basic duct layouts that struggle in sustained cold. With Columbia Gas service and frequent January inversions, homeowners need reliable heat and a clear plan when equipment starts failing.
When Repair Is Still Reasonable
If your furnace is younger than 12 years and otherwise maintained, a small fix—ignitor, sensor, control board, or blower capacitor—often restores full function. Typical local repairs cost $150–$1,000. Homes in newer subdivisions near Toronto Junior High usually benefit from quick part swaps and clean airflow. A technician should always verify heat exchanger safety before approving continued use, especially in older brick homes with narrow vent paths.
When Replacement Makes Financial Sense
After 15 years, corrosion, motor fatigue, and repeated part failures become common. Modern high-efficiency furnaces improve comfort and lower gas use by 20–30%. Installation in the $2,635–$5,610 range includes proper venting, labor warranty, and sealed combustion safety. For hillside homes above Ridge Avenue, variable-speed furnaces also even out airflow between floors, reducing the “cold upstairs, hot downstairs” problem that older units can’t solve.
FAQs
Do riverfront homes wear out furnaces faster?
Yes. Moist basement air and iron dust from nearby rail lines accelerate rusting. Annual cleaning helps extend service life.
How long does a furnace install take in Toronto?
Usually one day, but older masonry vents may require liner work or flue resizing to meet modern codes.
