Leicester's climate zone, in plain terms
Worcester, MA runs a January average near 25°F and climbs to about 71°F by July, a swing that adds up to roughly 6,623 heating degree days most winters, with 502 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Leicester, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Leicester's specific load is what tells you whether beating that floor is worth the extra cost.
