Dual vs Single stage gas furnace

[sjohnson]

We are needing to replace our furnace and ac this season and we have looked at Gibson and Tempstar. The tempstar guy suggested a dual stage furnace for our 2 story 1300 sf (plus basemetn) home in Iowa. The Gibson guy thinks the extra cost in repairs down the road aren't worth bothering with. I've read some of the posts about Gibson/nordyne, but don't have a feel for Tempstar. Any advice appreciated, either about the difference in the stages or the brands.

You want the new furnace to keep your house as comfortable as possible? Buy dual stage equipment from someone that can explain to you how it does this instead of the guy that says they cost to much to fix.

He still has roll up windows in his car,because power windows still have too many parts to break.2 stage variable the way to go.

Go two stage for the best COMFORT.. An equipement that is sized right (Manual J) for the home, you should never feel cold in any parts of the home. Also make sure they put in a two stage T_stat. Two stage furnace dose not have that much more parts than a single stage. just a variable speed blower witch is also a big plus in quiet in 1st stage.

Don't be afraid to buy the 10 years parts and labor warranity.
