A short pre-trip check can reduce the chance of returning to an avoidable problem.
Water
Look for active leaks around sinks, toilets, appliances, and the water heater.
HVAC
Don't shut down heating or cooling in a way that creates temperature or humidity problems for the house. Choose an appropriate setting for the season, home, and equipment.
Appliances
Follow manufacturer guidance for appliances that will remain operating.
Doors and windows
Confirm they're secured.
Exterior
Check for obvious conditions that could create problems while you're away.
Smart leak detectors
Remote water sensors can provide useful alerts while nobody is home.
Trusted contact
For longer trips, having someone who can access the house may be useful if a problem occurs.
