Need advice on which Trane components are better.

Hey Guys,

I am getting a new complete residential AC system installed in the next few weeks and I received two different quotes both for 3.5 Ton Trane systems. Both quotes are from competant and established companies so I'm not worried about the quality of the installation from either company but there is almost a $**** difference in pricing between the two quotes and as you can see below the condensor model is the same but the coil and furnaces models are slightly different. I'm trying to understand if there is any major difference in the components that are being used to justify the huge pricing difference. Between the two options below is one better than the other? Any assistance would be greatly appreciated.



Company A:
Furnace - S8B1B060M4PS
Coil: 4TXCB004
Condensor: XR14 (model 4TTR4042)

Company B:
Furnace - S8X1B060M4PS
Coil: 4MXCB006
Condensor: XR14 (model 4TTR4042)

Thanks,
Zak
