Fort Myers's climate zone, in plain terms
Cape Coral-Fort Myers, FL runs a January average near 65°F and climbs to about 83°F by July, a swing that adds up to roughly 252 heating degree days most winters, with 4,046 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Fort Myers, separate from anything a brochure claims.
Zone 2A's requirement is the floor; Fort Myers's specific load is what tells you whether beating that floor is worth the extra cost.
