With natural gas prices rising and GTA winters lasting five months or more, upgrading to a high-efficiency furnace is one of the smartest investments a homeowner can make. Modern furnaces with AFUE ratings of 96% or higher convert nearly every dollar of fuel into usable heat, dramatically reducing your energy bills.
Understanding AFUE Ratings
AFUE stands for Annual Fuel Utilization Efficiency. It measures how efficiently a furnace converts fuel to heat over a typical year. A furnace with 96% AFUE means 96 cents of every dollar spent on gas goes directly toward heating your home, with only 4 cents lost. Older furnaces often operate at just 60 to 80% AFUE.
How Much Can You Save?
Upgrading from an older 80% AFUE furnace to a new 96% AFUE model can reduce your heating costs by 20 to 40 percent. For the average GTA home spending $1,500 to $2,000 per winter on heating, that translates to savings of $300 to $800 annually. Over the 15 to 20 year lifespan of the furnace, you could save $5,000 to $15,000.
