What Jacksonville's climate means for your Sub-Zero freezer
Jacksonville's long, muggy summers put steady, year-round strain on anything that runs a motor or holds a temperature. Summer heat keeps the compressor cycling longer than the spec sheet assumes, and the humidity that comes with it feeds condensation inside the cabinet. It's routine on a Jacksonville call: check what the environment wears first, then confirm the actual fault.
