How Venice weather works your HVAC system
Fog tends to sit in through midday most of the year, so real cooling demand shows up only on the afternoons when the marine layer burns off early rather than across a long stretch of summer. Salt air off the beach is the bigger long-term factor for equipment here, so coated coils and a regular freshwater rinse do more for a system's lifespan than anything else we spec. That is baked into how we scope every smart thermostat visit. Heat load, dust, and how long the system runs day to day all get checked against the conditions of beach community homes and canal-adjacent properties before we start.
