What Fleming Island's climate means for your Master-Bilt walk-in freezer
Living on the First Coast means months of heat and heavy humidity — and your Master-Bilt walk-in freezer works against both. Summer heat keeps the compressor cycling longer than the spec sheet assumes, and the humidity that comes with it feeds condensation inside the cabinet. So on a Fleming Island repair we don't stop at the failed part — we check what the climate is quietly wearing next.
