Great forum. I have seen Trane listed many times as one of the many prefered heating systems. I am curious as to why I see Am Stanard listed rarely. Isn't it true they are both basically the same?

Also, I currently have two quotes. Both happen to be for American Standard and are within $100.00 of each other. One is for a 2-stage 60,000 btu unit(a heat loss was done with this quote) and a 2-stage 80,000btu unit. I live in Northern Indiana. Is it possible the 80,000 btu unit is overkill?

I also have a quote for a 2-stage 60,000 btu Rheem unit for $1000.00 less. Is there any reason I should not consider this unit?
