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
The Canada Greener Homes program and Enbridge rebates can offset $2,000–$5,000 on qualifying high-efficiency systems.
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.
