Two-Stage Gas FurnacesTraditionally, gas furnaces simply turned on and off, running a single fan speed to distribute heat. Later, as technology improved two-stage furnaces were developed to allow the furnace to operate at high speed when demand was greatest, and lower speeds when less heat was required. This improved comfort and save energy.
Three-Stage and Fully Modulating Gas Furnace TechnologyToday, furnaces can deliver heat with an additional third fan stage or even fully variable speed, providing greater comfort and improved efficiency. Instead of stop-and-go heating of yesterday, today's furnaces are able to finesse the exact amount of heat needed to keep your home at the perfect temperature while operating quieter and using the lowest amount of fuel.
