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. These conditions can affect components differently, so the exact fault still requires diagnosis.
