Quick answer
Hurricane AC prep in Miami means checking that the condenser is anchored with code-rated tie-downs, installing surge protection, considering an elevated stand in flood-prone areas, and knowing how to shut down and safely restart the system around a storm. After a storm, a flooded or shifted unit should be inspected before it runs.

Atlantic hurricane season runs from June 1 to November 30, and South Florida sees the most activity from August through October. Most AC damage we see after storms falls into three groups: condensers that shifted or tipped because tie-downs were missing or rusted, units that sat in flood water, and compressors and boards damaged by power surges when the grid came back.
All three are preventable or at least reducible. The Florida Building Code requires outdoor units to be anchored against wind, but tie-downs rust, bolts loosen and pads crack over the years. Surge protectors at the disconnect cost little compared with a compressor. And in low-lying areas, raising the condenser keeps it above most flood water.
We do a hurricane check as its own visit or as part of a spring tune-up, and after a storm we inspect and restart systems safely before running them.
