Before you leave your Florida home for the summer, set the AC to hold humidity below 60 percent, shut off the main water supply, clean out the fridge, seal food against pests, hold or forward your mail, arm security, and arrange for someone local to check the house on a schedule. Each of those matters, and the order is roughly the order things go wrong.

Amelia Island in July is not the island you left. It's hot, the humidity sits high for months, and the afternoon storms roll through on their own timetable. A house that's fine when you're in it every day behaves differently when it's closed and empty for four or five months. This is the walkthrough we'd run before you lock the door and head north.

Start two weeks out, not the morning you leave

The worst version of this is doing it all in the last hour. You forget things, you leave in a hurry, and the small stuff that prevents big problems gets skipped. Give yourself two weeks. That's enough time to schedule any service calls, get a pest treatment on the books, and confirm your insurance situation before you're gone.

Do a slow walk through every room with a notepad. You're looking for anything that's already a little wrong: a slow drip under a sink, a window that doesn't seal, a soft spot on a ceiling. Those are the things that turn into real damage over a long absence. Fix them now, while you're here to let a plumber or handyman in.

Water is the risk nobody sees coming

A burst supply line or a failed water heater in an occupied house is an annoyance. In an empty house it can run for weeks. The Insurance Information Institute lists undetected water leaks and burst pipes as one of the top risks for homes left unoccupied, and it's the failure that does the most damage before anyone notices.

Shut off the main water supply if you can. If a full shutoff isn't practical because of an irrigation system or an ice maker you want running, at least close the valves to the washing machine, and consider a smart leak sensor near the water heater and under sinks. Drain nothing you don't understand, but do know where your main shutoff is and confirm it actually turns.

AC and humidity: leave it running

The instinct is to turn the AC off to save money. In Florida that's the fastest way to grow mold. The EPA is direct about this: the key to mold control is moisture control, and indoor humidity should stay below 60 percent, ideally between 30 and 50 percent. A closed, un-cooled house here climbs past that within days.

So leave the AC on. The Department of Energy recommends keeping the house warmer than normal when you're away, not shutting the system off, and a moderate setpoint around 78°F with the fan doing its job holds both temperature and humidity in range. We wrote a full breakdown in what temperature to set your AC when away in Florida, and the companion piece on how to prevent mold in a closed-up Florida home covers the humidity side in more depth.

The refrigerator and the pantry

Decide early whether the fridge stays on or off. If it stays on, clear out anything perishable and anything that can spoil into a smell you'll regret in October. If it goes off, empty it completely, clean it, and prop both doors open so it doesn't grow its own science project in the dark.

The pantry is where pests get their invitation. Anything in a cardboard box or a bag is fair game. Move dry goods into sealed containers or take them with you. An empty, sealed pantry gives ants and pantry moths nothing to work with.

Pests find an empty house

Bugs and rodents don't wait for you to leave, but they get bolder when the house goes quiet. Get a pest treatment done before you go and, ideally, keep a service on a schedule through the summer. Seal gaps around pipe penetrations and dryer vents, because those are the doors you didn't know you left open.

Outside, cut back anything touching the house. Branches and shrubs against the siding are a bridge, and standing water in saucers, gutters, and clogged drains is a breeding site. A clean, dry perimeter is half the battle.

Mail, packages, and the "nobody's home" signal

A pile of mail, a stack of packages on the porch, and newspapers in the driveway all announce an empty house. Put mail on hold with the Postal Service or forward it. Stop recurring deliveries. Ask a neighbor to grab anything that slips through.

Small automations help. A couple of lights on timers, a car in the driveway if you can arrange it, and a landscaper who keeps the yard looking lived-in all raise the cost of a house looking abandoned for months.

Security and the alarm

Arm your system and confirm it's actually communicating. Test the sensors before you go, update the emergency contact list, and make sure the monitoring company has a local name to call. An alarm that dials a homeowner five states away and gets voicemail doesn't do much. This is exactly what a local keyholder is for: someone nearby who responds when a sensor trips at 2 a.m., checks the house, and tells you what they found.

Also handle the insurance side before you go. The Florida Department of Financial Services notes that a standard homeowners policy does not cover flood damage, and long vacancies can affect coverage in other ways too. It's worth a call to your agent, and we go deeper in does home insurance cover a vacant house.

Who actually checks on it

Every item above degrades over time. The AC can trip a breaker. A leak can start the week after you leave. A storm can drop a limb. A checklist is a snapshot, and a closed house needs a moving picture. That's the case for regular home watch visits: interior and exterior checks on a schedule, with a report after each one, so a small problem gets caught while it's still small.

For owners in condo and single-family communities like Amelia Island Plantation, where a lot of homes sit empty through the summer at once, having someone physically walk the property is the difference between finding a leak in week two and finding it in October. Lock the door with a plan for who opens it next, and the summer takes care of itself.
