Palm City, FL Climate Specs + Top-Rated Window Installers

Palm City's climate zone, in plain terms
Port St. Lucie, FL runs a January average near 65°F and climbs to about 83°F by July, a swing that adds up to roughly 256 heating degree days most winters, with 4,044 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Palm City, separate from anything a brochure claims.
Zone 2A's requirement is the floor; Palm City's specific load is what tells you whether beating that floor is worth the extra cost.
