How to Clean the Burners on a High-Efficiency Furnace

High-efficacy furnaces have an annual fuel utilization efficiency (AFUE) of 90 to 97 percent. They also have a sealed combustion chamber and a second heat exchanger that aids efficiency, according to the U.S. Department of Energy. Cleaning the burners on a high-efficacy furnace keeps it working efficiently all winter long. Dust and dirt can clog the burners on a furnace and make it not work as well. Bi-annual cleaning, once in the spring and once in the fall, keeps that from happening.
