What Middleburg's climate means for your Master-Bilt walk-in freezer
Summers on the First Coast run long and muggy, and a Master-Bilt walk-in freezer in Middleburg carries that load all season. 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 Middleburg repair we don't stop at the failed part — we check what the climate is quietly wearing next.
