How Long Do AC Units Last in Naples?

Plan on roughly eight to twelve years here rather than the longer lifespans quoted for inland climates, with homes closest to salt water sitting at the lower end. Salt in coastal air corrodes the aluminum and copper of the outdoor condenser coil, and once corrosion opens a leak path the repair is rarely worth doing on older equipment. Cooling season in Naples also never truly stops, so a system logs far more running hours per year than one up north. Maintenance genuinely buys time. Rinsing the condenser, keeping the drain line clear and catching a low charge early all add years back. Admiral Heating and Cooling of Naples treats every one of these numbers as a range and never as a guarantee.
