The benefit of a two stage furnace comes from the fact that it can run longer while putting out fewer BTU's to keep the house a more constant temperature. While it runs for a longer period of time it uses about the same or a little less energy than a single stage furnace. The monetary benefits of a two stage furnace are minimal at best. There is a higher initial cost along with the possibility of higher repair costs, with little energy saving ability. http://ths.gardenweb.com/forums/load/hvac/msg1021450611847.html http://www.warrenheating.com/prod01.htm Bottom line is that it is a comfort issue. If money is not the option a two-stage, variable speed furnace will give you the best comfort. If you want minimal upfront cost, go with a single stage furnace. If you don't mind a much larger upfront cost, but want long term saving, go with geo-thermal. There are obviously variable to consider, but the 10 year savings of a geo-thermal system can be substantial. http://www.eere.energy.gov/RE/geothermal.html Thanks!
