   Here’s a simple formula to estimate the furnace size you need: Square Footage of Your Home x Climate Zone Heating Factor = Total BTUs Needed. For instance, if you have a 1,800-square-foot home in Toronto (Zone 4), and you use a heating factor of 50 BTUs per square foot, you’d calculate: 1,800 sq. ft. x 50 BTUs = 90,000 BTUs

   Does furnace efficiency matter?

   • Note: Furnace efficiency doesn’t matter here. An 80 AFUE furnace (with 100,000 BTU rating) and an efficient furnace (94 AFUE 100,000 BTU) will both produce 100,000 BTU of heating output. It’s just that an efficient furnace will need less fuel (propane, gas, electricity) to create this output.
