Q: What does efficiency on a furnace mean?
A: If you have a furnace that is 80% AFUE, that means that you are getting 80% of the heat produced in real heat, and if it is 90%AFUE, that means that you are getting 90% of the heat produced.The remaining amount is lost through your furnace vent. If your furnace has a pilot light that is burning constantly, your furnace is probably less than 80%.
