Despite looking like the noise a sneeze makes, AFUE is a very important measurement in home comfort. AFUE, or Annual Fuel Utilization Efficiency, measures how efficiently a furnace converts energy from the fuel it uses to warm your home.

Think of it as miles-per-gallon for home heating.

The higher the AFUE, the better your furnace is at efficiently heating your home. For instance, our YP9C modulating gas furnace has an AFUE rating of 98%. That means 98% of every BTU (a measurement of a fuel's heat content) used to run the furnace comes back as heat for your home - and that's very, very efficient.
