Well, I think I have narrowed down my choice in replacing the upstairs unit with a 3 ton Trane 13 Seer and Furnace
The model numbers are:
4TTX5036a1 or 4TXCB036BC (not sure which one is the 13 SEER)
My question is another vendor quoted me an 80k BTU as opposed to the 60K BTU. Does that make a difference in what I am looking for? I essentially have 4 rooms upstairs I am trying to keep cool, but am clueless as to the importance of BTU's. Most of the people in my neighborhood have 3 tons for the upstairs as well and are happy, but they all have no idea how many BTU's they got.
Any help is appreciated.
