Unlike conventional, single-stage furnace technology, Goodman’s DualSaver technology eliminates the temperature swings resulting from abrupt, high-stage stops-and-starts of the furnace by operating at a low heating state the majority of the time. This gas furnace has an AFUE rating of 80% which means that 80 cents of every $1.00 of heating energy expense warms your home.
