What Fleming Island's climate means for your Sub-Zero freezer
Between the heat and the humidity, Fleming Island is a tough climate for a Sub-Zero freezer to age gracefully in. Summer heat keeps the compressor cycling longer than the spec sheet assumes, and the humidity that comes with it feeds condensation inside the cabinet. Knowing what Fleming Island's climate does to a Sub-Zero freezer is part of the job here — we check for it every visit.
