What Is AFUE and Why Does It Matter?

AFUE (Annual Fuel Utilization Efficiency) measures what percentage of the gas your furnace burns actually heats your home for the full list of terms, see our HVAC glossary. A 60% AFUE furnace wastes 40 cents of every dollar you spend on gas. A 96% AFUE furnace wastes only 4 cents you can check your own unit's rating on the EnerGuide label for furnaces. In Ontario, where furnaces run 6–8 months per year, even small AFUE improvements translate into meaningful savings.

Is upgrading from 92% to 96% AFUE worth it in Canada?

Usually yes for long-term homeowners: expect $60–$120/year in savings, with a 5–8 year payback if rebates apply, or 10–15 years without them.

Check the yellow EnerGuide label on your furnace, or look up the model number online models from that era are covered in our furnace brands guide .most units installed before 2000 run 60–78% AFUE.

Not necessarily a $100–$200 annual tune-up can boost efficiency 5–10% without a full replacement. Not sure which route makes sense? Compare with our furnace maintenance guide.
