Hoover's climate zone, in plain terms
Birmingham, AL runs a January average near 45°F and climbs to about 82°F by July, a swing that adds up to roughly 2,542 heating degree days most winters, with 2,186 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Hoover, separate from anything a brochure claims.
Zone 3A's requirement is the floor; Hoover's specific load is what tells you whether beating that floor is worth the extra cost.
