Natural gas and propane
Gas furnaces are common where utility service exists. Propane provides similar equipment options in rural locations but requires on-site storage and delivery planning. Both need combustion air, approved venting, condensate management on condensing models and carbon-monoxide protection.
Oil heating
Oil furnaces remain in parts of Atlantic Canada and in rural properties. Ownership includes tank condition, delivery access, spill prevention, chimney or vent condition and specialized service. A replacement decision should consider the whole system, not just the furnace cabinet.
Electric furnaces
Electric resistance furnaces avoid combustion and onsite fuel storage but can have high operating costs depending on local electricity rates and winter load. They still require correct electrical capacity, airflow and professional installation.
Compare the home, not just AFUE
Fuel price, utility availability, electrical service, duct condition, heat loss, backup needs and local contractor support can matter more than a single efficiency number. Request a heat-loss calculation and lifecycle comparison before selecting equipment.
- What changed immediately before the problem?
- Does the issue affect airflow, heat production or both?
- Is there an error code, odour, leak or repeated shutdown?
