Furnace manufacturers are required to post a unit’s energy efficiency information, including the AFUE, on a yellow sticker on the side of the unit. The EnergyGuide label outlines the estimated annual operating cost of the furnace, its energy efficiency level, as well as how it compares with similar units.
It is important to remember that furnaces, like any other appliances, become less efficient as they age. Routine self-maintenance and an annual checkup by a professional will help extend the life and efficiency of your furnace as well as reduce your repair costs and ensure that your manufacturer’s warranty remains valid.
