Belton's climate zone, in plain terms
Killeen-Temple, TX runs a January average near 48°F and climbs to about 84°F by July, a swing that adds up to roughly 2,032 heating degree days most winters, with 2,630 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Belton, separate from anything a brochure claims.
Zone 2A's requirement is the floor; Belton's specific load is what tells you whether beating that floor is worth the extra cost.
