Traverse City's climate zone, in plain terms
Traverse City, MI runs a January average near 23°F and climbs to about 70°F by July, a swing that adds up to roughly 7,104 heating degree days most winters, with 534 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Traverse City, separate from anything a brochure claims.
Zone 6A's requirement is the floor; Traverse City's specific load is what tells you whether beating that floor is worth the extra cost.
