Choosing the right furnace for your Ontario home is one of the most important decisions you’ll make as a homeowner.

Ontario Furnace Regulations & Requirements
Important: Since 2010, Ontario building codes require all new furnace installations to be high-efficiency with minimum 96% AFUE ratings. Standard efficiency furnaces (80% AFUE) are no longer permitted for new installations.
Ontario’s commitment to energy efficiency means homeowners benefit from:
- Lower energy bills with high-efficiency systems
- Reduced environmental impact through better fuel utilization
- Enhanced home value with modern, efficient heating systems
- Compliance with building codes for insurance and resale purposes
Understanding AFUE Ratings for Ontario Homes
AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts fuel to heat. For Ontario’s cold climate, here’s what you need to know:
| AFUE Rating | Efficiency Level | Fuel Waste | Ontario Status |
|---|---|---|---|
| 80% AFUE | Standard Efficiency | 20% wasted | Not permitted for new installations |
| 90-95% AFUE | High Efficiency | 5-10% wasted | Permitted but less common |
| 96-98.5% AFUE | Premium High Efficiency | 1.5-4% wasted | Required for new installations |
Ontario Climate Consideration: With heating seasons lasting 5-7 months in most Ontario regions, the difference between 90% and 96% AFUE can mean hundreds of dollars in annual savings.
Proper Furnace Sizing for Ontario Homes
Getting the right size furnace is crucial for efficiency and comfort. An oversized furnace will short-cycle, while an undersized one will struggle in cold snaps.
Manual J Calculation Factors for Ontario:
- Home square footage and layout
- Insulation quality and window efficiency
- Local climate data for your specific region
- Number of occupants and lifestyle patterns
- Home orientation and sun exposure
