First, thanks to everyone who has helped me get to this point. Your knowledge and assistance has been extremely helpful!

I have narrowed it down to Trane or Bryant and would appreciate your thoughts on the 2 systems.

My hose is as follows:

1,500 s/f single-story ranch over a crawlspace.
Mid Missouri
3 ton condenser - 9 SEER
75,000 btu gas furnace

Trane contractor suggested the following:

XR15 2-ton single stage condenser - 16 SEER
XV95 2-stage, variable speed gas furnace
"matching coil"
TCONT thermostat

Bryant contractor suggested the following:

127A 3-ton two stage condenser - 16.5 SEER
96T 2-stage, variable speed gas furnace
CNPV*3717A** indoor coil
T6 Thermostat

As you can see the biggest difference I see if the condenser unit. Trane being 2 ton single stage and Bryant being 3 ton two stage. The Bryant contractor said a 3 ton two stage would serve me much better than a 2 ton single stage.....

As far as I know, they both did pretty much the same load calculations.

Any thoughts would be more than appreciated!
