Overview for Goodman GDH81005CX

Unlike conventional, single-stage furnace technology, Goodman's Dual$aver 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. 

Please note that this product is regulated by DOE Efficiency Standards.
