Sorry Jeff.....My Bad
I have never printed the spec sheets so I turn my head and read sideways:wink:
You are correct, no B.
Did you ever say what size drive your existing furnace has? Since you have stepped your unit size down, I noticed that some of the VS 3 & 4 ton drives work with the 3636 coils.
Since you are keeping your existing furnace drive, you will never get a perfect system match, but now that you are in the 2.5 ton arena, it seems there are more options.
I have a Trane XV90 80,000 btu furnace. Dual stage burner, variable speed fan. It has dips witches for 2, 2.5, 3, 3.5 ton outdoor units.
Also dips for 350, 400, 450 CFM/TON.
So in theory if I set it to 3.5 TON and 450CFM/TON, the unit will try to do 1575 CFM...
I'm leaning towards the 2.5 ton 14SEER, and yes it is because of the coil more then anything. I think 2.5 Tons will be fine based on all my experiences thus far. I also plan to put in dampers and zone the house by turning off rooms we won't be in much, so 30,000 BTUs seems like it will be plenty..
