Energy Efficiency Rating System

The Government of Canada has implemented energy efficiency standards for some heating equipment and other energy-consuming appliances and products. Some provincial and territorial governments have also introduced energy efficiency standards. Generally, these standards establish the minimum acceptable energy efficiency level for specific types of heating equipment. After the standards are in place, non-complying models are no longer allowed on the market where the standard applies.

The Government of Canada and the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) have established a voluntary energy efficiency rating system for residential gas and propane forced-air furnaces to help consumers compare the energy efficiency of different products. The EnerGuide label with the furnace's annual fuel utilization efficiency (AFUE) rating is shown on the back page of manufacturers' brochures. Included on the EnerGuide label is a rating scale showing the range of efficiencies as well as a pointer showing the efficiency of the model in relation to others. There is a specific EnerGuide label for gas and propane furnaces and one for oil furnaces on the market.

Look for the EnerGuide Label

The higher the rating, the more efficient the model. Check where the EnerGuide rating is situated on the scale to see if the furnace you are considering is in the high-efficiency zone.

EnerGuide ratings are based on standard testing procedures established by accredited certification organizations.

The Heating, Refrigerating and Air Conditioning Institute of Canada (HRAI) administers and delivers the EnerGuide Rating System for HVAC equipment in all provinces except Quebec. In Quebec, the Corporation des maîtres mécaniciens en tuyauterie du Québec (CMMTQ) delivers the program.
