Yorktown's climate zone, in plain terms
Muncie, IN runs a January average near 29°F and climbs to about 76°F by July, a swing that adds up to roughly 5,262 heating degree days most winters, with 1,172 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Yorktown, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Yorktown's specific load is what tells you whether beating that floor is worth the extra cost.
