Hi everyone -

Just bought an older home, and the time has come to replace the circa-1966 American Standard forced-air gas furnace. The previous owners never added central AC, so we're doing that at the same time.

I've gotten estimates from a number of local reputable HVAC companies, and now am not sure which way to go. All are roughly the same price - so that's not the issue. (except the Bryant, which is almost double all the other quotes).

The house is approx 1700 square feet, 2-stories, with a finished basement and semi-finished attic. Ductwork is orignal galvanized steel, with supplies and returns in every room.

Here are my choices:

Comfortmaker
Furnace: C9MPN 100,000 btu/90% efficiency
AC: CAC4 36,000 btu/15 SEER

Goodman
Furnace: GMS9 90,000 btu/95% efficiency
AC: CLQ 36,000 btu/15 SEER

Trane
Furnace: XL90 100,000 btu/90% efficiency
AC: XL14i 36,000 btu/15 SEER

Bryant
Furnace: Plus90i 100,000 btu/94% efficiency
AC: 165A 36,000 btu/15 SEER

Assuming all the installers are equal, which equipment would you choose? I'm leaning towards the Trane - if only because the Bryant is so much more expensive.

Thoughts?
