How Venice weather works your system
A Venice system that seems to underperform in July is often fine, since fog holds in through midday most of the year and real cooling need only shows up on the rare afternoon when that fog clears out ahead of schedule, which is why calls about weak cooling often resolve on their own by evening. The bigger repeat repair here is refrigerant and electrical parts pitted by salt air off the beach, and coated coils with a regular freshwater rinse are what keep those parts from failing years ahead of schedule. That is baked into how we scope every heating installation visit, heat load, dust, and run time all get checked against what actually happens in Venice and surrounding communities, not a generic average.
