Hurricane season runs June 1 through November 30. The work to do is in May. Here is the short list, in priority order.
Whole-home surge protector at the panel. Under $500 installed. Catches the spike that fries refrigerators, garage door openers, and pool pumps when power comes back on after an outage. This is the single highest-value upgrade most homes can make.
A transfer switch or interlock kit. If you own a portable generator, plugging it directly into an outlet is a code violation and a back-feed hazard for line workers. A $400 interlock kit lets you safely power your essentials from the panel.
Whole-home standby generator. $9,000 to $15,000 installed for a typical Brevard home. Worth it if you have medical equipment, work from home, or simply do not want to spend a week in 95-degree heat with no AC after a storm.
GFCI and AFCI breakers in older homes. Required by current code in wet locations and bedrooms. Cheap to retrofit and dramatically reduces fire and shock risk.
Tree trimming around your service drop. Not strictly electrical, but the most common cause of post-storm outages is a branch on the line from the pole to the house. The utility company will not touch the homeowner side of the service.
A pre-season inspection in May is the cheapest way to find out which of these your panel actually needs.
