why? two stage over single stage heat

[Dano]

I'm trying to get some feedback from both installers and consumers regarding the true benefits if any to two stage furnaces. If they run 40% longer at less gas consumption that's fine, but now i'm using 40% more electricity running the blower for these longer periods..correct? does the more even heating (longer cycles) yield a lower thermostat setting since it is suppose to provide a more consistent temp. from room to room? (this does not refer to variable speed ECM units, I got enough to decide) Thanks to all ..

Im a consumer, no pro, but here is what I have experienced. I removed a

110000 btu relic and put in a 2 stage 2 speed 75000 - 51000 lennox, with A.C. motor, the lower btu heats more evenly, not as fast. I was oversized before, to much heat to fast. But I never use high fire unless I have been away, and the house is cold. Mine just got totaled in a flood , so now I am looking into a variable speed DC motor which consumes 66 to 75% less elec. DC motors I hear dont last as long, I am looking at a carrier and getting a 10 yr warranty , The DC variable speed is suposed to up your air seer value by half of a full point or a full point, and remove more moisture in summer.Electric cost is a concern for me ,Check out the DC motors. I understand GE makes them for all brands and have recently redesigned them adressing the reliabilty issues, but the PROs will take it from here
