The Snowbird's AC Shutdown Checklist Before You Head North

Leaving an Englewood home for five to seven months takes more than just turning the thermostat up, and doing it wrong is how owners come back to mold instead of a clean house.

The Snowbird's AC Shutdown Checklist Before You Head North

Don't Shut the System Off Completely

The instinct to save money by turning the AC off entirely while you're away is the single most common mistake owners make before heading north. A closed-up Florida house with no cooling running builds interior humidity fast, and within weeks that moisture shows up as mold on walls, in closets, and inside cabinets. Instead, set the thermostat to hold around 78 to 80 degrees and, more importantly, make sure it's also controlling humidity, not just temperature. A system that runs occasionally to hold humidity under 60 percent protects the house far better than one that's off.

Set Up Remote Monitoring Before You Leave

A Wi-Fi thermostat lets you check in on temperature and humidity from wherever you're spending the season, and most models send an alert if the reading climbs outside a range you set. That alert is often the only warning you get if the system trips offline, a breaker pops, or a leak starts, giving you time to call a local contact before a small problem turns into a return-trip disaster. If your thermostat isn't smart-capable, this is worth having installed before you leave rather than after.

The Walk-Through Before You Lock Up

Replace the filter right before you leave so it's clean for the entire time you're gone, not already loaded with a season of use. Clear anything blocking supply and return vents. Confirm the condensate drain line is clear so a slow clog doesn't back up over months with nobody home to notice. Leave a local contact's number, a property manager, neighbor, or your HVAC contractor, with clear instructions on what to do if they get an alert or notice water. Arriving to a flooded pan and a soaked ceiling after six months away is far more expensive than a five-minute check before you go.
