What does AFUE stand for?

AFUE stands for Annual Fuel Utilization Efficiency. It is a measure used to evaluate the efficiency of gas-powered heating appliances, particularly furnaces and boilers. AFUE expresses the percentage of fuel that is converted into usable heat over the course of a year. A higher AFUE rating indicates a more efficient appliance, meaning that it uses less fuel to produce the same amount of heat, which can lead to lower energy costs for the consumer and reduced environmental impact.

Understanding AFUE is essential for HVAC professionals as it helps them recommend energy-efficient equipment to clients, optimizing not only performance but also operational costs in the long run. Recognizing the importance of this metric allows technicians to make informed decisions regarding the installation and maintenance of heating systems.
