Aspen Aire provides a wide array of furnaces. These furnaces use gas to provide warm, comfortable heat for your home. You can compare efficiencies of different furnace models by checking the AFUE (Annual Fuel Utilization Efficiency) ratings. The published ratings provide a standardized method for comparing how much heating performance you get for the gas you use. For more information, check the PDF's attached to each furnace.
