Carrollton's climate zone, in plain terms
Atlanta-Sandy Springs-Roswell, GA runs a January average near 43°F and climbs to about 79°F by July, a swing that adds up to roughly 2,992 heating degree days most winters, with 1,688 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Carrollton, separate from anything a brochure claims.
Zone 3A's requirement is the floor; Carrollton's specific load is what tells you whether beating that floor is worth the extra cost.
