Frequently Asked Questions About Furnace Replacement in Ottawa, ON
How much does furnace replacement cost in Ottawa, ON?
Furnace replacement in Ottawa typically ranges from $2,500 to $6,500 installed, with an average around $4,200. High-efficiency 96+ AFUE models cost $3,500–$6,500 installed; standard 80 AFUE units run $2,500–$4,500. Variable-speed and two-stage models add $500–$1,000 but deliver better comfort and lower utility bills. Permit fees and any ductwork modifications are additional.
How long does a furnace last?
Gas furnaces last 15–20 years with regular maintenance. If your furnace is over 15 years old, needs a major repair (heat exchanger, inducer motor, or control board), or your heating bills have risen significantly, replacement is almost always the better financial decision. A licensed HVAC technician can inspect the heat exchanger — a cracked exchanger is a safety hazard and means immediate replacement.
What is AFUE and what rating should I look for?
AFUE (Annual Fuel Utilization Efficiency) measures what percentage of fuel is converted to heat. An 80 AFUE furnace loses 20% of fuel as exhaust; a 96 AFUE unit loses only 4%. For Ottawa, a 95–96 AFUE furnace delivers the best return — high-efficiency savings without the condensate and venting complexity of top-tier 98 AFUE units. Federal tax credits of up to $600 apply to qualifying high-efficiency furnaces through 2032.
Do I need a permit to replace a furnace in Ottawa?
Yes — furnace replacement requires a mechanical permit in virtually all ON jurisdictions. A licensed HVAC contractor pulls the permit, and the city inspects the completed installation. Unpermitted furnace replacement can void the equipment warranty, create issues with homeowner insurance claims, and create liability during a home sale. Always confirm your contractor is pulling permits.
