The Direct Comfort GCSS96 Gas Furnace with single-stage gas valve and a multi-speed circulating blower provides efficient and economical performance. A single-stage gas furnace provides more consistent airflow through constant rotation. Energy efficiency is key to controlling the cost of heating your home. The 92% AFUE rating on this gas furnace means that 92 cents of every $1.00 of heating energy expense warms your home. Some older central heating systems are rated at 60% AFUE. The Department of Energy (DOE) established the AFUE, Annual Fuel Utilization Efficiency, system to calculate the annual operating cost of residential gas furnaces.
