A » AFUE stands for Annual Fuel Utilization Efficiency, a metric used in HVAC systems to measure the efficiency of gas and oil furnaces. It represents the percentage of fuel converted into usable heat over a typical year. A higher AFUE rating indicates a more efficient furnace, leading to lower energy costs and reduced environmental impact. For example, an AFUE of 90% means 90% of the fuel becomes heat, while the remaining 10% is lost.
