Unlike conventional, single-stage furnace technology, our technology helps eliminate 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 up to 96%, which means that up to 96 cents of every $1.00 of heating energy expense warms your home.
