What Fleming Island's climate means for your Sub-Zero refrigerator
Summers on the First Coast run long and muggy, and a Sub-Zero refrigerator in Fleming Island carries that load all season. Long stretches of summer heat push the compressor and condenser to work overtime, and humid air feeds condensation and frost inside the cabinet. Knowing what Fleming Island's climate does to a Sub-Zero refrigerator is part of the job here — we check for it every visit.
