How does living near the ocean in Boca shorten an AC's life?
Salt is the problem. On the barrier island and in the neighborhoods along the Intracoastal, onshore wind carries a fine salt mist that settles on the outdoor condenser. The thin aluminum fins on the coil corrode and flake away, which cuts how much heat the unit can reject, so it runs longer and pulls more power. Salt also eats at electrical connections and the contactor, which is a common cause of a unit that hums but won't start. A coastal unit can wear out years before the same model a few miles inland. Regular rinsing with fresh water, coil cleaning, a coastal coating on new equipment and checking connections twice a year all slow it down.

What should condo owners in Boca know before replacing an AC?
Start with your association. Most Boca condo buildings have written rules on contractor insurance, working hours, elevator use and where outdoor units can sit, whether that's a rooftop, a balcony or a ground-level pad. Many also require a certificate of insurance before a crew can enter the building, so it pays to request approval early. The air handler usually lives in a tight closet, which limits what fits, and the drain line often ties into a shared stack, so a clogged drain can become a neighbor's leak. A careful contractor measures the closet, confirms the drain path and handles the paperwork before any equipment is ordered.
