Local conditions

What St. Johns's climate means for your Sub-Zero freezer

St. Johns's long, muggy summers put steady, year-round strain on anything that runs a motor or holds a temperature. Long stretches of summer heat push the compressor and condenser to work overtime, and humid air feeds condensation and frost inside the cabinet. Climate is one diagnostic consideration; it does not identify the failed component by itself.
