Alright here's the question:
I've got a
2800 sq ft house 3 bdr
built in 2005
below ground basement
open floor plan/high ceilings
One stage furnace
Denver, CO

I have heard that I could get a 4 ton 13 seer unit with a 5 ton coil
(trane) or go with a 5 ton 13 seer(rheem) with a 5 ton coil.
Will I get better efficiency with the 4 ton/5 ton coil trane?

Way confused! Thanks
