What zone 2A means for a Dunedin window
Tampa-St. Petersburg-Clearwater, FL runs a January average near 60°F and climbs to about 83°F by July, a swing that adds up to roughly 589 heating degree days most winters, with 3,486 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Dunedin, separate from anything a brochure claims.
Zone 2A's requirement is the floor; Dunedin's specific load is what tells you whether beating that floor is worth the extra cost.
