What St. Augustine's climate means for your Sub-Zero refrigerator
Living on the First Coast means months of heat and heavy humidity — and your Sub-Zero refrigerator 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. On a St. Augustine job we look at the wear this environment causes, so the fix holds past the next heat wave.
