Furnaces are the most commonly used residential heating system in the United States. Running most often on gas, but sometimes on oil, propane, or electricity, furnaces deliver their heat through a duct system. Furnaces that have earned the ENERGY STAR have higher AFUE (Annual Fuel Utilization Efficiency) ratings.
