What Fleming Island's climate means for your Master-Bilt walk-in cooler
Fleming Island'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. It's why we inspect the corrosion- and heat-prone parts on every Fleming Island visit, not only the one that failed.
