What about the trane S9X2 two stage gas furnace, would you recommend it for someone that is looking for long term replacement?

Roger......what determines which speed taps are used on the 2 stage furnace?

[@the-bu3lb]

if u have a 2 stage installed from the start why would u have a single in its replacement makes no sense correct expecialy if you added an addition within then 24 yrs right

Single stage is less expensive. That is why some choose to do so.

Maybe living in an area with very low heating needs.
