Performance and Time‐Tested Durability Delivered Quietly and Efficiently

Goodman's GHS80403AX energy‐efficient 40,000 BTU gas furnace with two‐stage heating and a circulating blower provides efficient and economical performance. Unlike single‐stage gas furnaces that operate "all on" or "all off," a Goodman brand multi‐speed ECM gas furnace typically runs up to 90% of the time in the low‐speed capacity on most days. But when the temperature outside is frightfully cold, this furnace quietly ramps up to high‐speed capacity to deliver all the warm, comfortable heat your home needs. This self‐adjusting feature works without an outdoor temperature sensor. When operating at low‐speed levels, your Goodman gas furnace consumes less energy to keep your home comfortable. In addition, the 80% AFUE rating on this gas furnace means that 80 cents of every $1 of heating energy expense warms your home.
