What zone 5A means for a Fishers window
Indianapolis-Carmel-Greenwood, IN runs a January average near 27°F and climbs to about 74°F by July, a swing that adds up to roughly 5,758 heating degree days most winters, with 920 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Fishers, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Fishers's specific load is what tells you whether beating that floor is worth the extra cost.
