What Affects the Cost?
System Size
A properly sized system costs more upfront but saves on energy bills. Oversized units short-cycle and wear out faster.
Efficiency Rating
High-efficiency furnaces (96%+ AFUE) cost $1,000–$2,000 more than standard models but qualify for rebates and lower gas bills.
Ductwork Condition
If existing ductwork is undersized or leaking, you may need modifications that add $1,000–$3,000 to an installation.
Government Rebates
Utility and government rebate programs can offset part of the cost of qualifying high-efficiency systems. Programs open and close, so confirm current eligibility before you buy.
Licensing in Ontario
Gas-fired HVAC work in Ontario requires a TSSA (Technical Standards and Safety Authority) licence. Always verify your contractor is TSSA-registered for gas work.
Frequently Asked Questions
How long does a furnace last in Ontario?
A well-maintained furnace typically lasts 15–20 years. If yours is 15+ years old and needing frequent repairs, replacement is usually more cost-effective.
Should I repair or replace my furnace?
A common rule: if the repair costs more than 50% of a new system and the furnace is over 12 years old, replace it.
Do I need a TSSA-licensed contractor?
Yes, for any gas appliance work. TSSA licensing ensures the technician is certified for safe gas installation and repair.
Are heat pumps worth it in Ontario?
Heat pumps work well in southern Ontario’s climate and can reduce heating costs by 30–50%. They qualify for significant government rebates.
