How Venice weather wears on your system
Fog holds into midday for much of the year here, so cooling demand concentrates into the handful of afternoons when the marine layer clears early rather than spreading across a long season. Salt blowing off the sand is the dominant maintenance factor, pitting uncoated coils and cabinet fasteners, so coated coils and a freshwater rinse schedule decide how long an outdoor unit survives. That is the starting point for a heating maintenance visit here, the checklist accounts for heat load, dust, and run time the way Venice and the Los Angeles coastline actually sees them, not a generic average.
