What St. Augustine's climate means for your Multiplex appliances
St. Augustine sees long stretches of heat and humidity most of the year, and that's exactly what wears on a Multiplex lineup. Salt in the coastal air corrodes exposed condenser coils and fan motors, while summer heat makes the compressor cycle harder to hold its temperature. Climate is one diagnostic consideration; it does not identify the failed component by itself.
