AFUE (Annual Fuel Utilization Efficiency)
AFUE (Annual Fuel Utilization Efficiency) is a measurement that shows how well heating equipment uses fuel. Think of it like a score that tells you how much of the fuel actually turns into heat for a home versus how much is wasted. For example, an [[AFUE]] rating of 90% means 90% of the fuel becomes useful heat while 10% is lost. This term appears frequently in resumes of HVAC technicians and heating specialists who work with furnaces and boilers. Higher AFUE ratings indicate more efficient equipment, which is becoming increasingly important as energy costs rise and environmental concerns grow.
