What St. Augustine's climate means for your Sub-Zero freezer
Living on the First Coast means months of heat and heavy humidity — and your Sub-Zero freezer works against both. The coastal air's salt content works on condenser coils and exposed metal, and summer heat alone makes the compressor run longer cycles to keep up. These conditions can affect components differently, so the exact fault still requires diagnosis.
