Just found this posting. I have to buy a new Furnace ASAP as my 25 year old furnace is no longer safe without $1,000 worth of repairs.
I have a 100 year old, 3 floors, 2300 sq foot house with bad insulation on 3rd floor.
I have got numerous quotes for a new furnace. Most sales people suggested I needed a 80 K BTU furnace (my old one was 100 K but mid eff) but that is where the consensus ends. Some suggested that I get a modulating furnace (Carrier 98 Infinity comes up most often) while some say I would be better with a two stage variable motor furnace (Carrier Infinity 96 or Trane VX95). I have read many forums and am more confused as there also seems to be differing opinions. Given the price between the modulating and two stage variable is only around $350 (and the modulating comes with Infinity wi-fi thermostat vs having to buy one ) I am strongly leaning towards the infinity 98.
I do have the following questions:
1. Putting aside price, given the age and bad insulation in my house, would the modulating be the better option to get heat to cold places places like my 3rd floor?
2. If i go in this direction, is Trane XC95 any better then Infinity 98 (which is cheaper and comes with the wifi remote where I have only been offered a non wifi more basic trane Thermostat)
3. If I am better instead with a two stage variable then is the Infinity 96 or Trane VC95 a better option (as they are a similar price)?
4. If go with a two stage furnace do I need an infinity/trane thermostat or can i simply buy a decent programmable thermostat?
Thanks in advance.

This may help you make a decision,
1. - If your thermostat is anywhere other then the 3rd floor then no not really. if its in the middle floor then it will keep the middle floor at whatever temp you set it at however the top floor may be a few degrees colder.
2. - Always heard Trane is high quality, however cant tell you if one is better then the other. you would want to compare the specs of both units side by side.
3. - See #2
4. - I'm pretty sure you can use any brand thermostat you want and it should work.
